On sleep resume, computer powers off

[ryan29121]

On occasion I am having a problem. When my computer is in sleep mode, sometimes on wake up the computer will just power off. Then I have to power it on. Most of the time it works fine, but about every 5th time it will power off. What would be causing this? Thanks in advance for your help on this subject.

Sometimes this is caused by a outdated or corrupt video driver. Try updating to the latest 8800 driver for Windows 7 64-bit from Nvidia's website, and see if the problem stops
