CPU wil not turn on.

Whatever the case, it is extremely frustrating to say the least. A simple 1/2 cent power button was between me tossing the computer for a new one or keep on throwing new parts at it until it worked.

I'll put $10 on the GPU. Once it went just too hot and thereby its thermal grease was severely degraded.

If that will turn up not to be the case, then I'll put $8 on the same issue with the CPU. But I doubt it.
The AMD should shut the system down at way lower temps that the 9800GTX will...

I replaced the 9800gtx with a 7950 gt to see if the 9800gtx was the culprit, and was getting the same results. The CPU is watercooled, so i dont know if it overheated.

I looked over the MoBo really good. I saw some capacitors that looked like they were "leaking", but some canned air and a toothpick cleaned the grooves on the tops of the ones that looked suspect to reveal that they were infact still good. (Hopefully)

The tracking # on the PSU shows it is at the UPS in Greensboro, NC, where i live, (arrival scan 1pm yesterday) but, they do not do ground deliveries on NewYears Eve, and I can't go pick it up because customer support there is off today. Oh well. Will be here Monday.

I have already have begun to look at MoBo's online just in case.
The one I am using now is a MSI K9N SLI Platinum.

Ok, I may have found out what is going on...

Haven't got the PSU yet, so I am not sure, BUT, after looking over each capacitor closely, I have noticed four beside the processor, that are slightly bulged. Not much, but they are not flat like the rest.

So, the MoBo may be the culprit. Can the capacitors be replaced, or, am i gonna have to get a new MoBo if in fact this is the problem?

R&Ring a mobo takes some skill. If you can do it, I guess so.

I'm assuming your mobo is out of warranty.

I would wait until I got the psu and tried it first tho.

I would see if Intrex could put new caps on the MoBo. I will try the PSU first, but I have a feeling those caps are blown, after looking at pictures online and reading up on them. They are raised ever so slightly. All the others are flat.

The board is 4 or 5 years old, so its not covered. I don't want to spend cash on a new MoBo, but if I have too i will. I am sure I can install it, but I have never installed a processor before and the whole thermal grease application would have me nervous. Plus a watercooler sits on top of it. It is not a repair I would feel 100% confident in doing. But I will try!

I have swaped caps on a mobo myself and have had it done a few times sicne I no longer have the tools to do so. Gotten good results each time.
