Hi,

Out of nothing, my pc doesn't boot anymore.

I turn it on, no screen appears and there's no beep. Then I see the HDD light running constantly. After 2 hours suddenly it restarts and goes on.

However, today it doesn't do it. I just stays the same, without any visuals, monitor in stand-by mode.

My monitor is fine. I refitted the battery on the motherboard, didn't work. Took all hardware out (except CPU) and refitted it, also didn't work.

System specs:
Q6600
MSI 8800GT OC
2x 250GB Seagate SATA HDD
DVD drive
650w PSU,

I've never seen or heard about this before. Have you? And what's the solution :D?

Tried other RAM, no success.
PSU or graphics card I don't have.

When I was just trying a few things, twice, after 30sec or so, the computer just shut down and didn't turn on anymore. Had to take the power off before it turned on again.

Anyway, no results.

Wondering if it might be the PSU?
