So recently over the last couple of weeks, my computer has been randomly restarting on me.

Today, it crashed and stayed off, and now when I try to turn it on the fans turn on for half a second then it cuts back off. I haven't been able to turn it back on since.

I don't know if I can test either, because my old ps/mobo had a 20 pin connection.

i'd put my money on the power supply if i were you

plus they're fairly cheap, just go get a new one

I had a prob sim to this on the x's pc..... bought a new power supply, still crashed. Determined it was the mobo..... too old to fix, so we built a newer one....

Don't cheap out on the one component that can kill all the rest.


Get a multimeter and test the power supply. You can jump back to green (I think that's it?) to get it to switch on and check the voltages.

My money is on the mobo, but have the memory run through memtest if you can have it done.

Any way to test which one it is that doesn't involve buying something?


If it's probably the mobo I may just grab a cheap one like this until I can get together the funds for a new PC.

^ With a multimeter you can rule out the power supply. To test the memory you need another system, if only for a few minutes.
