computer can't go into sleep mode (crashes if left alone)

I've had my computer for a little bit over a year now and it has worked fine. But now when I select sleep mode, the computer turns off the monitor but the fans are still going, it shows no sign of actually sleeping. Most of the time I can't get back to the login screen because the monitor remains black, so I have to force shutdown. If I leave the computer alone, it will eventually crash, so when I turn it back on it says the computer has recovered from blue screen.

I have read several threads but none managed to solve my problem. Some threads said video cards seem to be the problem but when I disabled my video card, the computer still couldn't sleep.

Sometimes, the computer does manage to go into sleep mode but its completely random.

Windows 7 Home Premium SP1 x64 (OEM)

Security Software: ??? Make sure to install security software. I recommend either of these:

• Microsoft Security Essentials - Free Antivirus for Windows coupled with Malwarebytes. Do not start the free trial of Malwarebytes. Just use the standalone version, update it, and scan your computer once a week with Malwarebytes and with Microsoft Security Essentials.
  
  
• Good and Free system security combination.

After installing your security software, update it, and then run full scans today with each program. Report back the results of the scans.

I do see remnants of ESET NOD32; is it still installed? It is not running...

Are the above intentional? If so, please provide an explanation so we can understand your troubleshooting steps.


Your crashes were old, but may still be helpful. The .dmp indicates graphics card related problems. I do notice an ATI overclocking utility installed that will not work with Windows 7 and may cause instability. Graphics card related problems can be caused by your DirectX/graphics card. DirectX comes installed with Windows, so this may indicate Windows corruption. It may also be that you have corrupted drivers or a graphics card hardware problem.

• If you are overclocking any hardware, please stop.
  
  
• Check Windows for corruption. Run SFC /SCANNOW Command - System File Checker up to three times to fix all errors with a restart in between each. Post back if it continues to show errors after a fourth run or if the first run comes back with no integrity violations. Use OPTION THREE of SFC /SCANNOW Command - System File Checker to provide us with the sfcdetails.txt file if errors occur.

Follow the steps for Diagnosing basic problems with DirectX. To re-install your display card drivers as outlined in the DirectX link, use the following steps.

1. Download the drivers you want for your display card(s)
2. Click Start Menu
3. Click Control Panel
4. Click Uninstall a program
5. For NVIDIA:
   • Uninstall the NVIDIA Graphics Driver (this should uninstall all NVIDIA software and drivers)
   • Restart your computer
   • Make sure NVIDIA 3D Vision Driver, NVIDIA 3D Vision Video Player, NVIDIA HD Audio Driver, and NVIDIA PhysX System Software are not still listed under Uninstall a program through Control Panel
   • If any remain of the above, uninstall one at a time
   • If asked to restart after uninstalling any of the above, do so, and continue uninstalling any remaining NVIDIA items until all are removed
6. Restart your computer after uninstalling drivers for all display cards
7. Install the driver you selected for the display cards once Windows starts

Remember to try multiple versions of the graphics drivers, download them fresh, and install the freshly downloaded drivers.

Great news! Let us know how things go with the next sleep cycle.

Try to do the sleep cycles that normally make the system crash, and upload any new reports if you do crash. Best of luck it is solved!

No go, the computer did the same thing when I put it into sleep. Monitor went black, fans kept running. It shows that the Power and Wifi lights are on but nothing else. After 15-20 minutes it shuts down; when I turn it back on, it gives me the options to boot into safe mode.

When I logged in this was the error message:
Windows has recovered from an unexpected shutdown.

Hmm, certainly explains why the wifi light is still on. I'll give it a try when I get home.

You're welcome. Let us know if you need any help finding a suitable driver. If you cannot find one through ASUS, I have a few other sources for your wireless device from other laptop manufacturers.
