Random power on issues

[scoobyx13x]

My fathers computer that I built for him a year ago has suddenly develop a strange problem. Sometimes, it refuses to power on. Flipping on off/on switch on the PSU sometimes clears it so does unplugging and replugging the power cord that goes to the PSU.

I'm thinking the PSU is going bad. Any other thoughts?

PSU is the Antec 450 SPII that comes withe the Sonata 2.

Could be the psu, or some gunk that has disrupted the contact on the power switch itself.

Scoob,

Even though the PSU is the main suspect, have you tried clearing the CMOS?

No, I haven't. Thats a good idea.

Psu or motherboard, but look into the PSU first.

PSU most definately, Ive had several boxes in my time do this exact thing. Replacing the power supply fixed it in all cases
