Dvd Drive Disappears From My Computer After Sleep


On windows 7, running on an hp pavilion p6020a desktop pc, after waking from 'sleep', my dvd drive no longer appears (disappears from) 'my computer'. The drive still opens/closes, but will not launch autorun or be accessed via explorer or a command prompt.

I have already removed the upper/lower value registry items when running vista (and they are no longer appearing when viewed with regedit either).

Cd/dvd Drive Disappears / Reappears

I seldom shut my pc down, usually put it to sleep. I'm running windows 7 - 64 bit on a gateway pc. Since installing win7, my dvd drive often does not show up on "my computer". I have to reboot, sometime a couple of times, in order to get it to show up again. The drive may show up and, when the pc comes back from sleep, it's gone. I read a couple of other posts about this that sounded
A bit different, i will appreciate knowing how to fix this issue other than having to reboot.

Cd-dvd Drive Missing Or Not Visible In Computer

Latest version of cdrom.sys driver is correctly installed and detected in "device manager". Reinstalling is not helping. High-low filters solution does not apply. Filter are not present. When opening the key with regedit. Window 7 automatic troubleshooter detect the problem with the statement "the drive is not assigned a drive letter" but cannot assign a new letter.

"Computer management" detects the cd drive but the drive letter is missing and the assignment a new one is not allowed: when trying to assign a new drive letter manually, the new letter assigned shows in the screen for about one second and immediately disappears again. Different drive letters have been tried in case standard "e" could be somehow locked by some other software or virtual disk.

Using "computer management" i can mount the cd drive it in a folder in other hard drive and explore/operate cd contents without problem. I am using this for the time being as a temporary solution for having access to information in my cds/dvds. This is happening in asus k52jr laptop with windows 7 home premium-64. Dvd-cd driver is a hitachi hl-dt. St dvdram gt30n.

Dvd Drive Disappeared When I Rebooted Computer

My dvd drive disappeared when i rebooted computer after removing suggested programs before i upgrade to windows 7 64 from vista 64. Now i can't launch the dvd? The upgrade advisor suggested i uninstall itunes, intel proset/wireless, and bluetooth stack for windows by toshiba. It also had me upgrade the driver for my panasonic mfstation scan. After i completed those items, the installer had me reboot computer. Now, i am unable to open the dvd as the drive is no longer visible, and the dvd does not automatically start when i insert it into the drive.

Flash Drive Is Recognized Then Disappears

I bought a lexar twistturn flash drive in december. It has functioned wonderfully with windows xp and vista, but my computer with windows 7 on it has given me problems. The computer is a compaq that came with windows 7 pre-installed. When i plug the flash drive into any of the usb ports, it is recognized and autoplay starts, but about ten seconds after the autoplay window opens, it closes and the flash drive is no longer recognized. This continues in a cycle for as long as i leave
The flash drive plugged in.

I have googled this problem to death, and have found no solution. I also contacted lexar tech support and was told that the problem is likely being caused by the pre-installed drivers. I have checked that my the os is up to date (it is), as well as trying to find drivers to re-install on the manufacturer's website. They may be there somewhere, but i have been unable to find them.
I'm pretty much at the end of my rope with this problem: please help?

Computer Sleep

I set my computer to sleep after 30 minutes. It did go to sleep. When i moved the mouse to wake it up, only the wallpaper loaded up. No icons at all. I had to turn it off by the on and off button on the tower. Not a good idea, but that was the only way i could restart my computer, after it turned on again all my icons were there and i was able to resume all the functions again. Any ideas how to set it to sleep without this problem? This is a new windows 7 computer. Hp pavillion elite 137c

Computer Wont Come Out Of Sleep Mode

My computer wont come out of sleep mode. Screen will go black after some time. Than using the mouse and keyboard wont wake it up. The screen stays black. Yet the light on the monitor stays green instead of orange (it has signal but nothing is there) i have to hold the power button and kill it than reboot to get the screen back. I never had any hardware problems in xp but im new to windows7 and still getting familiar with it. Figured somebody would ask some system specs.
I just installed windows the other day and downloaded newest drivers for everything. Also got all automatic updates.

In power settings turn off the display is set to 10 minutes, and sleep mode is set to never so im guessing its not really going into sleep mode. I now went in and looked at some settings and made some changes. In advanced settings i turned off hybrid sleep (i dont know what it does) i saw selective usb suspend setting that was enabled (dont know what it means) could that be turning off my mouse and keyboard thus why i cant wake it up? I turned off all sleep mode features now. And disabled all hibernate/turn off display features. And am going to let it sit for awhile and see if it does it again. I will report back if this works.

Computer Won't Sleep Properly

My computer generally works and sleeps ok (when i manually put it to sleep) . However, once a day or so it fails to go to sleep on its own . And i find it powered on, but non-responsive. Pressing the power button (for under a second) causes the computer to power off. And then when powering back up (with the power button), it does a full boot (not a resume).computer is windows 7 professional 64-bit on an intel core i5 with 4 gb memory, latest bios and drivers.

How do i go about fixing/debugging this problem? I will copy the "powercfg -energy" report . It may help you note a specific problem that i can fix.

Computer Shuts Down After Awake From Sleep Mode

I just built a new computer with an asus p7p55d premium motherboard. When i try to wake the computer from sleep mode (i've tried both s1 and s3 sleep modes in the bios), the fans start to run and the motherboard leds turn on, but then the computer just powers off. I then have to turn the computer back on, wait for the bios to load, and then i get the "windows was shut down unexpectedly. Start windows normally or safe mode?" Prompt.

I've tried changing all of the settings i can think of in the windows 7 power options, as well as in the asus bios menu. A friend of mine said it might have to do with acpi settings, but it doesn't seem to change anything when i enable or disable them in the bios.could it possibly be a physical hardware problem? Does anyone have any ideas?

Windows 7 was installed on my pc . The dvd-cd-rom icon doesn't show up when i click on my computer. I only see the c-drive and the floppy disc drive. How do i trouble=shoot this? I tried the microsoft diagnostic tool in network/security on the control panel. The icon temporarily showed up, then disappeared.

Hard Drive Full After Sleep Mode

Problem occurred after upgrading from vista to windows 7.coming out of sleep mode, or logging in after computer left running unattended for several hours, c drive is full. Going into sleep mode/log off, c drive has 377/456 available. Have changed to dynamic drive and eliminated other partitions. Did not fix problem. No error codes. Restart clears up the problem and c drive goes back to normal space available.

Some additional information:

If computer left running and in lock-up problem occurs over time.

Normal steps taken to fix: defrag, minimized services, ran troubleshooter etc. Have run virus scans/spyware scans etc. Have searched forums for similar issue. Found something in vista forum regarding system restore taking up available drive space. So i have set maximum shadow storage to 10gb. Won't know for a while whether this fixed the problem. I doubt it though, because default max shadow storage was set to 30% = '40gb and problem was consuming 377gb.

I traced the offending files to the pc tools application internet security and/or registry mechanic in the common files subdirectory. There was an xmlfile in there that grew until all available drive space was consumed. I tried to get support from pc tools but all they suggested was downloading the current application versions, which i did, but to no avail.

I was at first unable to delete the file because it is in use when the apps are running in background. However, by changing the settings to turn them off at bootup, and using the disk cleanup application below, i was able to delete it.

External Drive Disconnects After Sleep Mode

Twice in the past month i have awakened my computer from the sleep state to find that the external drive was no longer recognized. I had to disconnect the fire-wire cable and reconnect it for the drive to be recognized. At the same time my bluetooth phone lost its connection with the bluetooth adapter on my computer. I did nothing differently as far as i know on these two occasions than on any other similar occasions. Does anybody have any thoughts on what might be happening?

Readyboost Issue: Computer Won't Display Physical And Virtual Dvd Drives

After some nasty bsod and a clean reinstall of windows to resolve that problem i've noticed that sometimes after startup the computer won't display correctly the physical and virtual dvd drives. And the system is too slow. I tried in several times to restart it to see if the problem will disappear but the restart process was taking ages to complete. Till i've disconnected the 4gb sdhc card which was dedicated to readyboost. I tried restarting the computer without the sdhc card in it. Went fine. Everything was ok till i inserted back the card then suddenly the computer slows dramatically stops responding and the problem mentioned above reappears!

My question :is it really a readyboost issue or  some tech fault from my computer? And what can i do to fix it. Now i'm using the computer without the sdhc card and the readyboost function.

My pc config is: toshiba satellite  a 300 intel core2duo centrino 1, 83 ghz 4gb ram
And the driver for the card reader is from o2 and it is the latest one!

Usb Hitachi Deskstar Drive Won't Sleep

Old title: hitachi deskstar hds722020 won't sleep the drive is an internal deskstar sata drive which is connected to my externally to my computer via caddy / usb. The problem is that the drive will not go to sleep. I have win7 configured for the hard drive to sleep after 60 minutes and it refuses to do so. Perhaps the win7 configuration relates only to the primary c: drive?  Additionally, i have another external seagate drive which respects the win7 configuration of 60 minutes.

Downloading Of Software Disappears

For the past few months whenever i go to download software from the internet or download a pdf file, they never show up. I get the download status window and it tells me that it is complete, but i always either download to my desktop or my documents and nothing ever shows up. I even do a search for the file and windows vista tells me it does not exist. This is getting very irritating and hoping that coming to this forum helps. I am not sure if it is a some setting that has changed or what. Looking forward to any help.

Usb Fails / Disappears From Explorer And Cannot Be Reconnected

I have just installed the formal release, having played with the release candidate for several months. I had, and still have a problem with usb. When trying to copy to a usb disk, the system hangs after a very short time. The usb device in question disappears from windows explorer and cannot be reconnected. Switching to a different usb port results in the system failing to load a driver for the device saying it is not recognized.

The only option is a close down and reboot. As well as usb disks, i have this problem with an archos mp4 and an ipod. It makes the system quite unusable i'm afraid. I'm running on an intel quad system and apart from the above, and a missing co-processor driver, everything seems ok.

Minimize, Maximize And Close Button Disappears

For some reason the minimize, maximize and close buttons disappear on top of my windows. This is so for all applications. The buttons are not visible, but they still work. For instance, if i click in the top right corner of the application, the application will close.
 
I don't know what causing this. Sometimes it happens just after i started my pc. Sometimes it doesn't occur for over an hour. I've tried to detect the reason, but i wasn't able.
 
I've surfed the internet trying to find a solution, but couldn't find anything that works (they speak of nvidia drivers often, but there isn't a nvidia driver in my laptop. ) Does anyone have a solution for this problem?
