Not Able To Use All Of Installed Memory


I have recently did a fresh install of windows 7 64-bit. I upgraded from windows vista 32-bit edition. Here's the problem.

Before i upgraded i had all my current hardware running on my vista os with no problems with the memory. I had 3gb and was able to access and use 3gb. After i installed windows 7 my memory was still fine. It showed 3gb and didn't not report that any less was only usable. This morning i log onto world of warcraft and notice everything running slow. After i installed windows 7 it was lightning fast and looked great. Now i only have 1gb of memory available to use.

I have read as many things about this problem (as i could stand) before deciding to post this. Everything is the same except is a 64-bit os and a newer edition of windows. If my bios was not a problem in vista why would it be in windows 7.

I have ran the memtest. I have prowled the bios for any way to better control the memory. I'm left with believing that the problems originates from windows 7 and i hope there is a fix for it soon. I'm gonna try restoring windows to about a week ago and see if my memory returns.

Installed Memory Versus Available Memory

I have installed windows 7 64 bit as a clean install on a second disk in a system with windows vista 32-bit running on the 1st disk. The install went fine, and the system is running well. However, when i check the system resources i am told that there is 4 gb of memory installed but only 3. 49 gb available. Is this because i have the windows vista disk in the system. The mbr shows both systems are bootable, and the windows boot file and winload.exe are located on the vista disk drive.

This leads me to believe that i have inherited the 32-bit memory restriction on windows vista. On another system, a new laptop that came with windows 7 64bit pre- installed, also with 4 gb memory, the system resources show that there is 4 gb of memory, without any restriction on what is available.

Nvidia Chipset Installed With 1 Stick Memory Only

I have an abit nf2s  "405 geforce 6100" onbrd video set at 256mb enable if no other mother board and i have always had to install vista 32 with 1 stick and shut down install 2nd stick boot into safe mode and msconfig it to check memory box to 1532mb of the total 2048 1gig each stick and check permanent boot box okok and restart. Then i can install the nvidia 15. 76 driver shutdown install nvidia vga card nvidia 7600gs and windows would recognize and unistall onbrd videoo and restart and i would install the driver for 7600gs card 195. ? And good to go i ran for a year and installed to sp2 worked good. I have to do the same for windows 7.

Abit is no longer around and i have the newest bios and tried different memory ran memtest for a month, and msconfig was the only thing that stopped bsod and corruption and windows update failures if it would install by turning memory down and all memory options off, but i was wondering how to do a bcedit and if this would be more correct.

Cmd
Bcdedit
Bootcfg /raw /burnmemory=512 /a /id1

I dont have it quite right for the commands, but if i new how to set this then i could remove my msconfig portion and the shares video memory part would be corrected, maybe and would i still have to install with 1 stick of memmory and then do the cmd bootcfg with the second stick from safe mode setting. Its like the shared 256mb of the on-brd video was never set correctly for shared memory with both sticks. I have always had to double this 2048-512=1532mb and i could boot into windows and not crash i even got a exchanged new brd 3 or 4 years ago same thing too.

I could never use any thing from windows disc after that need to get dvd burner to create a new repair recovery new boot disc. But it recovers just fine from windows restore point side. Just dont restore from the first 4 or 5 restore points until completely installed to the 7600gs video card.

Dell Netbook - Installed Memory 2gb (1gb Usable)

Windows 7 on dell netbook - installed memory 2gb (1gb usable) - why can i only use 1gb of ram? How can i make all 2gb usable? I have a dell inspiron mini 10v netbook. It came with 1gb ram and windows 7 starter. I upgraded to windows 7 ultimate and like it much better. Since memory was only 1gb i installed a 2gb chip instead. The computer/bios is happy with it but windows 7 will only use 1gb of it.

Win 7 Do Not Show Full 4gb Ram Memory Installed

Windows 7 home premium & ultimate both do not show full 4gb ram memory installed. I have been running vista 32 bit on my sony laptop, hp dv6000 (bought a year ago). Intel core 2 cpu t5300 @ 1. 73
In vista, i was using full 4gb of memory installed. And it was fast. I disabled everything for "best appearance" and it was just a stripped down xp, running decent fast (as compared to win 7 after installation).

I tried to install first the 64 bit win ultimate, the result was slow and sluggish. I noticed that i was only using 2. 99 gb of 4. 0gb memory installed. Which is weird since i upgraded, why did i loose my 1gb memory. I then installed 32 bit win home premium on a partition, the result is again slow and sluggish. And now again i am only showing 2. 99 gb usable, instead of the 4. 0 gb installed in the control panel>system and security> system. How can i regain my lost 1gb back. We can cross out the possibility of an old os, since it was running 4gb with win vista at a comparable very fast speed than the win 7. Thanks .

Repartition Memory Stick / Memory Card

How to repartition a memory stick or a memory card? So, i bought an 8 gb memory card and figured i could create a couple or a few partitions on it; perhaps exfat and fat32 ones. I fired up the disk management program only to find out that the flash memory disk has the shrink/extend/delete volume controls greyed out. I did manage to shrink the volume using the disk-part command line program but couldn't use it either for creating new volumes.

Where does this seemingly ridiculous and pointless restriction stem from? I only found a couple of instructions on how to partition a memory stick using some shady third party programs.

Upgrade From Xp - Do I Need To Have Xp Installed ?

If i buy a windows 7 upgrade, and upgrade from xp to windows 7 do i need to have windows xp installed, because i currently have a virus and can not get into that hard drive, is it possible to present a old cd during the installation? Xp home edition to windows 7 home premium, currently i have a corrupt version of windows xp on it, would that be sufficient, is it possible to run the upgrade from the boot disk, even when i have a corrupt installation because of the virus.

No Device Installed

I recently completed an os install. I went from xp pro to windows 7. It appears that everything installed correctly and it was even able to update a few drivers. That being said i am having one major issue and i'm seeing a lot of redundant and incorrect information on the net. I'd like to post in respect to what i've done and see if perhaps i have missed something. Before we start here a few important stats about my machine:

Os: windows 7
Motherboard: asus sk8v
Chipset: k8t800

My sound card:
sound blaster live! (Wdm)
Model: sb0200

This issue is:

The speaker icon on the bottom right of the tool bar has a red x indicating the following under the "playback tab": "no audio devices are installed".

 Under the "recording tab":
"Microphone"
"Logitech"
"Microphone (pro 4000)"
Default device:there is a green circle with a check mark beside the microphone icon.

My headset is the logictech pro 4000. It is a headset and microphone all-in-one. It is powered by usb. If i plug the device in my playback shows this headset as my sound. There is no option to change to another sound device because windows 7 does not recoginize the sound card. When i look in device manager under sound it just shows the headset. I've tried removing the headset driver then rebooting with the headset unplugged. It simply puts the driver back on. I've tried downloading several sound blaster drivers, the problem is when you try to install these drivers the install stops because it reports there is no sound blaster device on the machine. I've also tried running a driver from windows vista, no go. What i need to figure out is how to make the device manager recognize the sound card. I think it's coming up under the heading of: 
Other devices-
                      -Multimedia audio controller
                      -Pci input device

I think that is my card because:
1. It clearly states it is an audio controller
2. It is plugged in via a pci slot

So again my question would be how do i make the device manager or windows 7 recognize the multimedia audio controller recognized as sound blaster? If i can get the system to recognize the card as sb then i am sure i can get the drivers to do their job. Windows compatibility page states there are no drivers for this device, and the solution is to go out and get a sound card that is compatible with windows 7.

This card ran flawlessly on windows xp. As a matter of fact i had multiple sound options installed. I used the logitech headset with microphone for online use with ventrilo. I used the sound card separately with a different set of headphones and an actual microphone for doing voice i created a "karoke like" player where people could sing along with songs from a host of different applications like itunes, limewire, jukebox etc. So i know the sound the card works. I just need to make windows 7 recognize it.

Where Is Xp Mode Installed?

Windows 7 ultimate x64. I ran the installation for xp mode. At the end of the installation there was a check-box to run xp mode on exiting the installer. I unchecked as i had some other things to do. I am now trying to find how to start xp mode. There isn't anything on the start menu for xp mode so how do i start it the first time?

On a side note - why is the installation package so dumb about where to uncompress its files to?  The installation package was on an internal sata drive with almost 300 gb free in the partition. The c: drive is on a sata drive with 183 gb free in the partition. So where does the install uncompress to - to my x: drive which is an external usb drive. Needless to say the file copying was a bit long.

Using Un-installed Fonts

I use a graphics program, paint shop pro, to create a many types of graphics. I have collected a large number of fonts (close to 50, 000)over the years which i use in creating the graphics. I do not install these fonts, i simply save them in a folder and then retrieve them as needed. In all prior windows operating systems, i was able to open an un-installed font, minimize it to the taskbar, and the font would show up in the list of fonts available in my graphics program, then when done with the font, i closed it.

Other programs also worked on this premise in using uninstalled fonts. This allowed me to have extreme flexibility in selecting and using fonts from my collection without the necessity of installing extra fonts into the system. This option seems not to be available in windows7, i open a font i want to use, minimize it to the taskbar, but it does not show up in the list of available fonts in my graphics program. Is there a way around this without having to install and use a font management program?

Memory Used Up

I have a dell mini 9 with 7. 07 gb capacity. I need to reload mc afee and there is not enough room. I am using 6. 95gb with 121 mb free. A lot of the usage is for 2 items - microsoft.net framework2. O, service pack 2 (183 mb) and framework 3. 0 using 179 mb. There are only 3 games on there using very little space - even if i deleted them, the mcafee wouldn't have enough room. Is there some way to reduce the size of these files, delete them, or do something so i can reload mcafee? I have cleaned, defragged, everything else i could find to help. Any more suggestions?

Print Driver Is Not Installed

Driver doesn't work with my laserjet 2100. During the driver install, i used "windows update", it then locates the driver, and seemingly installs. Afterwards, when the printer is accessed, it errors. When i go into the printer console, it tells me ". Print driver is not installed. " I go back to device manager, and the driver is named, and seems that it is installed. Very frustrating. (I'm connecting to a printserver via wireless across to my local network to a print server). I have several other pc's running 2000, xp, and vista with no problems.

So in summary, after the driver is "installed", i get an error accessing the printer, and subsequently get an ". Driver not installed. " Error message during the troubleshooting period. Windows "troubleshooter" did not find any issues. Also, the printserver has a static ip address and i used that address in setting up the printer port. Now what?

2.7 Out Of 3.00 Installed Ram Usable

I'm running windows 7 ultimate 32-bit and have 3 gb of ram installed in my computer. 32-bit editions of windows are supposed to be able to use up to 3. 2 gb of ram or something like that. However, when i look at a detailed performance report, it says that only 2. 70 gb of my 3. 00 gb installed ram is usable. Why is this?

Another Program Is Being Installed. Please Wait

Windows 7 professional: "another program is being installed. Please wait until that installation is complete, and then try installing this software again.

I upgraded this compaq cq50z-100 from vista home basic in a 2-step process:windows 7 home premium upgrade windows 7 professional upgradeonce i had upgraded to home premium, i started getting this message.

Thinking i may resolve by proceeding with the win 7 pro upgrade, i proceeded with the upgrade (success, no issues). However, the problem persists. I tried performing a 'clean boot' and then 'normal startup - load all device drivers and services' and i still get this error. Need advice on what to do to resolve this issue. Short of recovery to the original vista home basic image saved via norton ghost 15.

Installed Vs Usable Ram

I had a quick look at some other threads which talks about usable ram being shown less than installed ram. Mine is also same case. In my case, my windows 7 x64 ultimate box shows: installed memory (ram): 4. 00 gb (3. 75 gb usable). I understand that . 25 is gone, due to other devices/motherboard etc. Now my question to experts: considering that there are no hardware changes and if i add 4gb more ram (making total 8gb of physical ram), then what will be the value of my usable ram?

Windows Cannot Be Installed To This Disk

"windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's bios menu. ". I encountered this error after somehow magically overcoming the cd/dvd drive device driver error that's killing like half of the microsoft windows community, i swear. I'm trying to install win7 onto a 80gb hdd, after using the raid tool featured on my sata controller to format it to clear the way for this install.
Thoughts? Ideas?

Wrong Language Installed

Somehow while i was installing win 7 i ended up getting ukrainian installed. It only was visible on the calendar. All the rest of the screens and dialogue are displayed in english. I changed the calendar settings and now everything is in english.

Here is my problem. When i try to install office 2007 the dialogue window is in ukrainian. How do i fix this?

Since writing this i have checked region and language account settings. In advanced/copy settings i found ukrainian in welcome screen options. I changed everything to english and restarted. The issue is still there.

The opening dialogue box for office 2007 is still in ukrainian.

No Sound Device Installed

I have upgraded from vista 32bit to windows 7 ultimate 64bit, i have not made any hardware changes, apart from formatting my hard drive and then clean installing windows 7. It i saying that i don't have a sound card, which i do, i have a creative t9700, i cannot find drivers for it and when i troubleshoot it to let it find its own drivers it returns without any drivers. I have installed windows 7 as a present for my father who hates me going anywhere near his stuff because i am cursed with this unlucky streak of if it can go wrong it will.

Os Installed In Wrong Partition

I've recently installed windows xp home edition to my pc. It was only after a few days i've noticed my os was installed to my last partition (g:), which is only 4 gigabytes, when it supposed to be on drive (c:). I made 5 partitions by the way. Does this also contributed to the reason my monitor turns to power saving mode few minutes after playing games? I wanna know what should i do to fix this? My knowledge on computer systems are near to none by the way.

I have a feeling copy and paste to drive (c:) ain't gonna work, probably one of the dumbest ideas i have right now. I'm really hoping there's a way to fix this without having to format my pc.

I've tried everything. I've uninstalled and reinstalled the drivers i've resumed factory settings and when i did that everything worked fine until the updates installed themselves last night while i was running a virus and spyware scan. Is there any way besides trial and error to figure out which update screwed up my sound?

Memory Issues

I have a dell e510, 3. 0g ht processor, geforce 8400 video, . I had to install win 7 64 with just 2gigs of ram. After the install i added in another 2g of ram. It booted up and is working fine except its showing 4gigs with 3. 25 usable. I installed another gig of memory for a total of 5gig, (which my bios shows properly), but win 7 wont boot with the extra gig. So the 2 questions are, why is it only showing 3. 25 usable? Is that a vid card memory thing? And 2, why won't it take the other gig of memory when the bios recognizes it fine?

Memory Leak

Hi guys, ok so for the last few weeks i've been trying to fix this but i cant and now im all out of ideas so im hoping someone here will be able to. The problem occurs when im installing a game, after a minute or two while its installing my memory usage will start increasing and it does this all the way up to 99% where it will sit until i reboot my pc.

Now this only happens when i install a game, i can do anything else and its fine ie play games, encode videos, move files etc etc all fine. Right, things ive tried so far. First thing i did was open task manager and see what was using up the memory unfortunately there wasn't anything there that was using it even so i still shut down every single process and it still was at 99% memory usage (btw this takes forever to do when your memory is maxed out).

I tried running sfc/scannow (nothing wrong), next thing i did was run memtest 86+ all night (10 hours) no errors. After that i ran prime95 blend test all night (10 hours) no errors, then i ran disk doctor on all my hdds and fixed any problems it found. After all that didn't help i decided to format my pc and start afresh so i reinstalled vista 64 thinking this has got to fix it, but no it didn't. This all just happened out of the blue after my system was running fine for nearly a year.

Missing Memory

Where is my missing 1gb of ram? I have just purchased an acer asipre r3610 4gb ram with windows 7 home premium 64 bit os. I have read on the web that on a 64 bit os i should get the full 4gb of ram is this correct? Msinfo32 advises me i have installed physical memory (ram) 4gb but then says total physical memory is 3gb. I have spent numerous hours reading the web looking for answers.

My bios correctly reports i have 4096 mb of ram. Msconfig "advanced options" the "maximum memory" is unticked. After checking in resource monitor, i found that 1025mb of ram was "hardware or bios reserved". My inbuilt video card nvidia ion (latest drivers 195. 62), nvidia graphics utility tells me it has 256mb dedicated video memory, 64 mb system memory and 1215 mb shared memory.

I can only assume that this 1025mb ram that is "hardware or bios reserved" is part of the 1215 mb that my graphics card reports is being shared. How can i stop my graphics card from reserving 1025mb ram. Is this something to do with my bios or the way windows 7 handles/assigns memory?

I have read on the web that on a 64 bit os i should get the full 4gb of ram is this correct? I also believe that http://www.microsoft.com/whdc/device/display/graphicsmemory. Mspx says that turning it off shared mvideo memory in the bios doesnt disable the windows feature. Is this correct?
