Asus 4770 Issues

[kaesin]

Seems to run alright, however... whenever my wife starts playing WoW it plays fine for about 5 minutes and then the PC restarts. Every time. Upgraded from an X700 and well, I didn't have these issues with it on her PC. Any help on why it's doing that? Faulty card, or?

What power supply is in there? The 4770 doesnt require a ton of power but it requires significantly more than an x700 and that may be the source of the issue.

PSU is the OCZ Stealth X Stream 700W.
