Well I don't know if this belongs here, but oh well.

I'm having a strange issue with a family member's computer, I've never see anything like this.

I go to power on the computer, the monitor keyboard and mouse act like they want to turn on, e.g. the mouse will flash on and then back off real quick. The computer never gets to post, it keeps running and running, I even left it on all night but it never does anything.

I tried taking the CMOS battery out, that didn't help either.

I tried turning the computer on with no peripherals in, that didn't help either.

Not sure where to go from here, help would be appreciated.
