Solved: Shutdown on Startup

Hey, this computer has been running fine for a long time...it had done this a few times in the past year, but always solved itself.

Power it on, shuts down after half a second. Like I said, usually fixes itself, but now I've tried it at least fifteen times after cleaning the tower thoroughly and checking all connections and nothing (powering it on with nothing connected). I'm assuming this is a PSU issue? Perhaps it's on its last legs. This computer is a few years old...XP SP3, 2GB DDR2, ASUS motherboard off the top of my head..

Thanks.

 

I'd say you need to check your PSU by swapping it out and it wouldn't hurt to put a new CMOS battery in just to be sure the bios is in running order. Either one can cause issues like this. Jazz

 

Never had a CMOS error nor has the computer sat for a long time...though if the PSU doesn't fix the issue I'll look into it.

Any recommendations on a PSU?

The stock one was a Ultra X-connect 500w X-ULT500P...the computer has a medium load I'd say.

 

Test your psu !
