I recently upgraded to a Athlon 64 with the Epox 9npja ultra board. If I leave the computer for an hour and then try to switch to a user in XP it crashes with Stop code 0x50. I tried reinstalling Windows and I still get the error.

Most things I find say it is caused by a bad driver but I have not been able to find out which one. The dump file does not say which driver caused the error.

The BugCheckParameter3 is always the same value, 80505bbd. Even after my reinstall of windows.

Here is the dump:

Yea a did a full reinstall etc.

After playing the uninstall some app, wait a day, retry game. I found that it was caused by Pivot Pro' ">http://personalcomputing.portr...ducts/pp_overview.html which comes with my monitor.
