I have a problem with an Optiplex 755 PC running (32-bit) Windows 7 Professional. I just installed the operating system last week, and ever since, it seems to crash when I lock the screen. It doesn't happen immediately; it's usually after I walk away, so a few minutes (but I'm not sure exactly how many).
I have this non-specific error in the Event log. I've run a chkdsk, thinking it might be hard drive-related, but that didn't help. Any ideas on what to check and how are appreciated.

This question will most likely be voted to be moved to SuperUser, which is a better forum for problems a single user is having with a single personal computer. Don't double-post this question there; it will be moved automatically when enough people vote for the move. – mfinni – 2010-11-17T21:03:39.607
