Computer wont boot normally, PSU?

When I turn my computer on, the power button light flashes on, then goes off, then back on again, it never used to do this. If I leave it off overnight, i have to turn it on about 3 or 4 times before I can get it to boot into safe mode, because the power keeps going off on it almost instantly after turning it on..

Once this happens, I can go into safe mode (what I am doing now) Or try and let it boot. Previously it would boot after 2 or 3 attempts, but now it will not. I have tried removing the GPU, no effect. I have checked that everything is plugged in properly.

How can I be certain what is causing the problem?

It's more than likely the PSU, as you have suspected. The easiest way to be certain would be to plug in a known good PSU and see if the problem persists.

How can I tell what PSU I need... Mine seems to have different parts to it, for the harddrive it has two small cables, for the motherboard one big connector, and a small 4 plug connector directly beside it in the same...slot

Also: How can I load up the graphics cards drivers in safe mode? I did it for the audio, and now I can hear, but I want to try it for Video as well.

Shameless bump. I'll see about getting a PSU to borrow tomorrow.
