I've updated every driver for everything on my computer. The only thing that I have not updated is the BIOS only because I don't have a floppy drive yet.
I'll look into running memtest86 tonight.
I don't know if this only is happening on everquest 2 because I don't have any other intensive programs to test it on.
The game only crashes straight to the desktop. There are no error messages or blue screens. However, before I turned it off, it used to ask to send the error to Microsoft each time.
