Is my motherboard fried?

Gateway Gt5678 desktop pc - intel core...
September 13, 2009 at 18:47:38
Specs: Windows XP, intel core 2 q6600 quad-core
I let my computer get too dusty and it overheated, and now when I turn it on nothing comes on the screen. I bought a new power supply, cleaned and reapplied thermal compound on the heat sink and unplugged/ replugged in everything.Still nothing, what should I do next?

Why did you replace the PSU...was it fried? Dust traps heat and can definitely kill hardware prematurely.

If the PSU fried, it could have taken the mobo with it....very common issue.
Best thing to do is make sure all components are seated properly. do you fans/drives spin? Any beeps?

I tried a different power supply to see if that was the problem. It isnt, the fans still work...dont know about the beeps though. I have reseated everything, except the cpu. Thinking about taking it all out and putting it back together. I want to troubleshoot, so I know if I need to replace the mobo or cpu or if it is just an easy fix.

OK, I recommend this...

First, take the motherboard out of the case. Remove the power supply, one memory stick, video card and processor, from the case as well.

(Now... make sure you are standing on an antistatic surface)

Lay the motherboard out on a flat surface on an anti-static surface (preferably wood and/or antistatic sheet).
Next, add the memory stick, video card (if not onboard) and processor. Make sure they are all seated properly.

Next plug in the power supply and attached the connectors to the motherboard. Then, find the two pins that the case power leads (ATX-PW etc) connect to. Now, touch a small flat screwdriver over both of these pins briefly (don't touch anything else). The board should power up and you should see if it posts, on your monitor.

Using that method, if it doesn't post, your motherboard is most likely bad.
