Specs: Windows 7 Ultimate, Intel Core 2 Quad 2.66 GHz / 4094 MB
Okay, so I bought a Cooler Master Hyper 212 last week to help me keep my q8400 under Tcase when O.C. to 3.4GHz.

I hadn't had any problems so far when upgrading from a Gateway 838GM. First I replaced the mobo and ram from an intel 915g chipset to the gigabyte g31 es2l, and from 1gb of ddr1 to 4gb of ddr2. After upgrading motherboard I re-installed my OS windows 7 ultimate. Like your supposed to. Than I got my hands on a EVGA gt 220, and the week after that my intel core 2 quad q8400. I was happy I had made a whole new pc.

But I couldn't O.C. with that stock cpu cooler. So I bouth a cooler master.

I disembled my pc to install it. I thought I had done everything correctly, but the computer wouldn't start. So, I rechecked the front panel connector from the power. I think I may have made a mistake.

My PC would turn on but I had no signal. I thought it may be the video card, but when I hooked the VGA cable to the motherboard graphics and still no signal. So I don't think its the video card since the fan in it still spins and everything. The CD and DVD drives didn't open eather so I thought it maybe the PS.

I bought a raidmax case that include a 500w PS. The PS is not the problem.

What is my problem is it my motherboard or can it be the cpu?

please somebody help!

Well, it was like 73C or 75C on full load on one of the cores. I brought it back to 3.0GHz but it would still get to 70 71 on full load on one of the cores, so I left it alone @ 2.66 until the new one arrived.
Yeah dude, I used the thermal paste remover 1 & 2 to clean it up, and than applied artic silver.

Can it be the CPU than? because I just ordered another motherboard.

71°C underload is fine.

Try to reinstall CPU and clear CMOS.
Start the system without memory and if u hear beeps then CPU and board is fine(onboard speaker must be connected).

I changed the CPU to an Intel Pentium D 930 I had before the Q8400 to check if it might've been the problem. I did as you said. I took the RAM out and cleared the CMOS, but still nothing. I get nothing on the onboard speaker.

Not only that, I reasembled my old pc using the old case, mobo, ps, and IP4. I did what you said. I didn't put any RAM (because I don't have any DDR1) and I heard the 4 beaps its supposed to make.
