I just installed an Nvidia GT 620 in my system. My Power supply is 450 watts and am running Windows 7 64 bit. While the card is in the system (even without drivers installed), it will freeze and then need to be restarted at random times (even during POST!).

It's not a driver issue because the old drivers were uninstalled and the new are not in yet. The card is brand new so I can't imagine it being defective. The minimum wattage required on a PSU is 350 watts and I have a more than adequete PSU.

Can anybody help me?
