I recently built a pc with a X800GTO for my gpu
I have-
530W hiper PSU
dfi nf-4 mobo
3500+ Athlon 64
512 mb ram

but when I turn it on, half the time it will show the image, but the other half of the time, no image will appear on the monitor

I tested it with a friends 6200, and it worked every time

what could be the problem?
