Computer Restarts if when using bigger amoung of memory

[CountDraco]

HEY every time I play a video game or run a video my computer restarts on me........
Windows brought me to this page once http://support.microsoft.com/?kbid=322205

and when I open up the error message it gives me theses files
C:\DOCUME~1\James\LOCALS~1\Temp\WER4c4e.dir00\Mini070207-02.dmp
C:\DOCUME~1\James\LOCALS~1\Temp\WER4c4e.dir00\sysdata.xml


If you know what might be causing this I would like to know.... Thank you

Do you only get the crashes when using newly added RAM?
Are you certain the new RAM matches the specifications of the RAM that was already in your computer, and/or that your motherboard supports mixed RAM types?

Well the last Ram I bought was a year ago......Here's what happened:
I was running Windows 2k for almost two years when I ran into a virus that I could not get rid of. Well I decided it was time for a change so I wiped my C drive and installed Windows XP Pro. Well I reinstalled everything (Drivers and Programs) and well I tried to play SWG (Star Wars Galaxies) and the Computer rebooted almost instancely. Well I have tried reinstalling the drivers, reinstalling most of the programs, removing each memory card one at a time checking to see if a bad sector on one, I use a program called speedfan to check my harddrives and all of them say running at 78% or better...I know my computer CPU runs hot Pentium D's run at 150+ Degrees F, but I bought a new CPU Fan and it runs 100F regularly and 110F when in use of a SWG...I am not sure what may be causing the problem....
