I have recently bought an NVidia GTX470 and when i first tried it, it booted fine, then the PC wouldn't come back on, after fiddling around i got 5 fast beeps, then it powered down as soon as i powered it on, now after taking it out, and putting it back in making sure all the wires are fitted it comes on, first time it froze at the windows welcome screen (horizontal line) now it's booted fine and been on 10 mins, the drivers are working and i'm getting basic 3D graphics.
I am assuming it is my crappy 800w winfast power supply, but i need ur advice
