I posted a couple of days ago regarding my pc freezing whilst playing games. Today however things got worse.

I was watching a video with a game on in the background when all of a sudden my pc shut itself off without warning.

I tried to turn the pc back on but all I got was a second of lights/fans spinning and then it turned off again.

I removed the graphics card and tried again, this time it worked for more than a second, I thought it must be the graphics card. However now the problem has returned, even without the graphics card it still won't work.

I've tried the paperclip test on the psu and the fan spins when powered so it looks unlikely that's the culprit.

I've tried just one stick of ram in different slots, and I've tried no ram. The motherboard doesn't even beep to say there's no gpu/ram it just shuts off after a second.

I've read that maybe the board is shorting on the case but I haven't checked it out yet, can anyone help?

Well I tried almost everything to get my system to work but nothing I did worked.

I ended up buying a new motherboard and CPU and that fixed the problem. As I mentioned in my first post I tried removing different components in order to determine what was broken and I narrowed it down to the motherboard/CPU. I tried a different PSU and it still didn't work either.

Since I had an older setup having to replace either a mobo or CPU basically meant replacing both since the newer mobos and CPUs arent compatible with my older parts.

So yeah, long story short either my motherboard or CPU was dead and after replacing both my system works again. If you've tried everything like I have and have and it still doesn't work then you may be in the same boat I was, unfortunately.

You were in the exact same boat I'm in, unfortunately. My mobo/cpu are so old that I can't just replace one of them. And replacing those two also means replacing the memory. And replacing that means potentially replacing the PSU...
