Windows 7 PC crashes after being locked a few minutes
- by White Island
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. :)
