What does the BSOD say?
It usually reboots quicker than I can get all the info...I'd have to find the dumps to get all of it.
...and exactly what have you done lately?
It started after the most recent updates for Win7. Like I said, I re-installed Win7, and let it update. The only other program on the HD was System Mechanic Professional. I didn't really give it a chance to see if it would happen without the updates, which is why I was going to try a re-install again since I'm pretty much fresh.
However, yesterday I ran System Mechanic's registry fix and it found 399 errors! It fixed them all according to the program. I haven't experienced one since then, but I've not done much on here since then either. I guess I'll wait and see. The 399 errors really surprised me though...
