Well.... I read on the back of my Graphics card box that the card i have needed a min of 300w power and i looked at my PSU and it only had 250w MAX, so i went out and get myself a "Hiper Power Low Noise 350w" PSU fitted myself! But since ive got my new PSU i have found my games (Black and White 2 and Oblivion) have started to freeze and reset the computer! Didnt have them two games before i got my new PSU! Does anyone think is MAY be the PSU or not? My system is: Pentium 4 2.8ghz 1gb ram 256mb GeForce 6600 Which is enough is run both them games fine!! Thanks!!!
