Doesn't power on until I hit power button a few times

[billtimbob]

Upgraded my computer with a new CPU, motherboard, RAM, and HDD a couple weeks ago. The first week it worked fine, no problems. But over the last week, I've sometimes have had to hit the power button multiple times to get it to turn on (no more than 4 times). I've even hit the power button on the motherboard to make sure it wasn't my case button going. The fans don't start to spin or anything. Since my PSU has been working fine for 3 years, I'm thinking it is my motherboard. Is it worth RMAing while I still can?

2x4GB Ripjaws 1600mhz RAM

750W PC Power & Cooling Silencer II PSU (Keep in mind the PSU has been working fine for 3 years)

I think it is more likely the PSU is dying because it has been working for 3 years.

Can't tell if you're serious...

Anyone know? Also works if I hold in the power button for a couple seconds.

I told you, try a new psu. It is most likely the psu's problem. If if isn't, then we can look at the mobo. If it is the mobo, return it since you are still on warranty.

So you think it's just a coincidence that the PSU that has been working for 3 years broke within the same week I got a new motherboard/RAM/CPU? I don't have another PSU to swap in...

Well, you upgrade your computer so why not put the old mobo back and try?
