I'm past my ability here sure could use some help. My problem is on starup (or rather restart). System is a few YEARS old ASUS MB, P4, 512RAM, ATI Vid, WIN XP SP2. When trying to restart (have always had occasional problem with ATI driver crashing) XP will get to 'Loading personal settings' then the mouse will stop RESPONDING vertically, the screen will go black, then go to the BSOD (or its XP equivilant) I think (onlyabout a third of the characters are rendered) but I can see the 1 to 100 counter checking the drive. Then it restarts in an endless loop.
I can get it to START in safe mode. I have tried to revert to previous working versions. Run an AVG virus scan. Tried to install the latested and greatest ATI driver (to no avail, I think because some install driver does not load in safe mode) (I could not update AVG for the same reason). I tried to reinstall XP SP2 (my slipstreamed version of XP and SP2) it HUNG up on the last restart and when I restarted manually, back to the loop. I tried Trend Micro's house call on line virus scan but just came up with a long list of 'vulnerabilities that could...'Have you tried removing that card and re-seating it ? ?
Check the contacts for crud as well. Clean them with Q-Tips and alcohol.

Might not be the problem but it won't hurt either...
