My friend recently completed his comp, and put in a Radeon 9700...Only problem is, the whole system seems to die after Windows XP loads (everything just shuts off...). I took a look and thought that his Power Supply was kind of dorky (250). So I got him a 350 watt. Still the whole system dies. We tried putting in a Geforce 4 4600 and it worked fine for both of the power supply units. Now I think his 9700 is a defect. Still, the power supply part bothers me, since I have a radeon 9700 in a 250 PSU. Should I be concerned about that?
