For the past couple of weeks have been getting random restarts on one of my PC's Dell Optiplex 745 SFF XP Home 2gb RAm OnBoard Video Ran chkdsk and found 1 error, it was fixed. Checked memory and it passed memtest. Updated the graphic card driver. Ran SFC/scannow. Still get the reboots
couple Dell at work started doing this too. Right after the last 3 security updates from windows update., hrmm.
