Symptoms of a faulty power supply

post #1 of 6
Thread Starter 
I am currently experiencing frequent and unexpected shutdowns.

I managed to scan all partitions in between shut downs and everything seems to be clean.

It shutdown once and I couldn't get it to restart and I couldn't even jump the power supply on.

But now its turns on and runs for a while and then another unexpected shutdown.

I'm 99% sure its the PSU but can anyone verify this?

advice or solutions suggestions are appreciated.

Thanks

First make sure the heatsink is completely seated against the CPU because if one corner is loose, the CPU can get a lot hotter than normal and make the BIOS shut down the computer.

Can you borrow a PSU to test?

Use a digital multimeter (cheap ones are fine for this, even the one Harbor Freight often gives out for free or $3) and measure all the positive rails, both at idle and full load, and compare the numbers. If they're within specs (deviate by no more than +- 5% from +5V, +12V, and +3.3V) AND the idle versus full load radings don't vary more than about 5% (despite the fact ATX specs allowing twice 10% total deviation), then the PSU is probably OK.

It would help if you told which PSU you have

@shilka
It's a stock Hp PSU

@larymoencurly
I doubt it's the CPU, I have it water cooled and its been running fine for 6+ months.
