I just ordered a whole system worth of new parts from Newegg. Got them home, put them together, tried to start up. The case and CPU fans and the case LEDs came on for a few seconds when I flipped the switch on the power supply. Nothing happened when I pushed the power button. No fans, no lights, no beeps.
I disconnected everything except the case fan from the PSU and tried a paper clip test. Fan spun for several seconds with no problem. Powered up a DVD drive just for the hell of it, that worked too. Plugged the power supply into the motherboard and stuck the paper clip into the appropriate pins from the back, and both the case fan and the CPU fan spun. The PSU has no voltage selector, so I'm assuming it wants regular USA voltage.
Removed the video card (mobo has onboard video anyway). No change. Removed memory. No change.
I now have the mobo sitting on a cardboard box with nothing on it but the CPU, CPU fan, and a speaker; I left the power supply in the case and just stood it next to the box to hook up the power again (remembering to connect both the 24-pin ATX plug and the 4-pin CPU plug). It behaves the same as it did when everything was in the case and connected.
I removed and replaced the CMOS battery. Shorting the CMOS reset pins makes the speaker click once and the fans spin for a second. I hooked up the case power switch to these pins to test it, got the same result. Manually shorting the power switch pins on the motherboard has no effect.
It seems like the motherboard is just dead and I should send for a replacement, but I was wondering if there might be something I'm missing. Note: I don't have any electronics testing tools handy. Just screwdrivers and a paperclip.
I did the build on a wooden table while standing on a stone floor. No wrist strap but I touched the inside of the case plenty. I can't rule out the possibility of accidentally frying something on the motherboard myself, but I handled everything pretty carefully. There are no visible defects on any of the mobo components.
Specs (all parts new):
Gigabyte GA-Z68A-D3H-B3 Socket 1155 ATX motherboard
Corsair TX650M 650W power supply
Intel Core i3-2100 CPU with stock cooler
Thermaltake SopranoRS 101 mid tower chassis
G.SKILL Ripjaws 2x4GB DDR3 memory
EVGA GeForce GTX 560 graphics card
WD Caviar 750GB HDD
hp 24x CD/DVD Writer
Any suggestions?
