So when you run a second copy your PC just reboots?

Windows XP defaults to rebooting for a lot of crashes, but you can re-enable the "blue screen of death" instead, which may give more detailed information allowing you to home in on the problem.

Right-click "My Computer" -> properties -> advanced -> startup and recovery -> uncheck "automatically restart".

(not sure about other flavours of Windows).

Next time you get the problem you'll probably see the blue screen instead of just a reboot - something near the top in amongst all the tech gobbeldy-gook might give a clue as to the problem area - seeing that you've replaced RAM I'd suspect graphics card/drivers, or maybe motherboard.
i have already done uncheck on reboot for windows errors, and it still jumps to the reboot
