Today I was installing a new heat sink in my wife's computer, and I think I may have potentially damaged the motherboard. I've tried a few things to figure this out, but I'm just not sure.
First, here is the build, used mainly for gaming and internet:
ASUS M4N75TD AM3
EVGA 01G-P3-1373-TR GeForce GTX 460 (Fermi) Superclocked
AMD Phenom II X4 965 Black Edition Deneb 3.4GHz
G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3
ARCTIC Freezer 7 Pro
Antec TruePower 2.0 480W 24/20pin Power Supply
There is also a CD/DVD-RW drive, as well as a media card reader.
The overall build is about 2 years old, though the power supply is from a previous build and is probably closer to 5 years old. I used it because I didn't have the money at the time to buy a new one, and it seemed to have just enough power for the build. I don't think this was the cause of the problem.
This isn't the first time I've built a computer or installed a heat sink, though I only do this once every few years, and I only do it as a hobby. However, I know the steps to take be careful, and I always use the manual when doing such things (this stuff is too expensive not to).
After I got everything installed, I plugged in a power cord to make sure it all worked. The DVD drive light came on, the hard drive light blinked, my motherboard's leds were on, and all of the fans were working. Assuming I succeeded, I went to put it back at her desk and the monitor would not get a signal from the computer. I tried the second monitor port, but got nothing. Thinking I damaged the GPU, I installed an older one, but got the same result. This time, I tried using the mouse and keyboard, and noticed that they weren't getting any power.
I moved the computer back to my work table, plugged it back in, and turned it on. I tried a USB flash drive in each of the usb ports front and back, and it did not work in any of them. I took another more powerful power supply that I use in my own computer, plugged in the bare minimum, and tried again, but still got nothing from the USB ports.
As far as I can tell, I didn't miss anything when wiring up the power supply.
Does anyone here have any other troubleshooting suggestions? I am glad that it doesn't appear as though I broke the GPU, but I am rather upset with myself that I might have broken the motherboard.
