computer will not turn on every time

[silvere]

I'm selling my old computer (the specs below)and I've recently ran into a problem. it won't turn on every time. there's no ryem or reason to it. sometimes you can hit the power putton 20 times without it working. usually I have to unplug it (but not always) and that doesn't always work. I've tried I different cpu, memory and psu so I'm sure it's the mobo. anyone ever hear of something like this or know if there's a fix? it's overclocked, but it's rock solid

honestly I can spell...that should be rhyme instead of ryem and button instead of putton

This happens mostly when you're system doesn't get enough power.
420w should be enough though for almost every PC.
