I thought I might try here first since I know a lot of people around here have been using Windows 7 for awhile now, and so have I. My OS has developed a highly annoying issue recently, at some point when the computer enters sleep mode or standby, it simply shuts off. This issues is less than a week old as I downloaded Star Trek Online over night with no issues on the 12th and it was sleeping when I woke up and recovered just fine.
The only thing that I have done fairly recently was install an All in One Epson Printer, it's wireless and came with a Fax Utility (all of which is Win 7 compatible according to Epson). I just can't figure out what this issue is. I forced my computer to sleep for a few minutes and it woke up after that. But if I say walk away for as little as 30 minutes and come back, it's shut down again. If I am using it, nothing happens so I just don't know how to figure this out.
Some other forums have suggested something is overheating, but that doesn't make sense to me because I can play a game for hours and not have this issue. It's only happening when the computer goes idle and I am pretty sure when it is in standby or sleep mode. Short of telling my computer never to enter sleep mode again, any ideas?
Oh in addition to the printer, there was also a couple of updates to Adobe's Reader, some Security Updates from Windows and I think an nVidia driver I updated. I also know the exact time it stopped working because a backup was in process.
