My homebuilt computer won't turn on anymore. I'm going to outline EVERYTHING I've done to give as much information as possible. The symptoms leading up to this are as follows:
I was in the middle of some work, when both monitors stopped receiving signals. Nothing changed noticeably on the computer (fans kept running, same small amount of noise from HDDs and PSU). I waited a bit, nothing happened. Unplugged and preplugged the monitors, nothing happened. Pressed the power button once, and the monitors got signal again, and a few of the programs (not all!) and a few of the tabs open in my web browser (again, not all), had crashed.
I then did some more work a bit later. The same thing happened, except this time, following the same process, nothing happened. So I held down the power button till it shut off, and tried to reboot it. Nothing happened. From there I unplugged the computer, waited for a while, plugged it back in, and tried again. Still nothing. I started to troubleshoot. Tried a lot of things, then removed *EVERYTHING* that doesn't need to be plugged in for the computer to POST (it would never even post, much less get to bios). That means the only things plugged in now are the mobo, cpu, and ram. Still, nothing.
Then I decided that it could be my power button. So, I shorted the two wires on the mobo that would start the psu and computer, and nothing happened. Even shorted the reset wires, and still nothing. However, it was odd, because one of the leds on the mobo was on (always on, as long as the psu was plugged in). But still, nothing would happen. For me, first step is always to test the psu. So, I unplugged it from everything, and shorted the power to the ground (green wire to black). Lo and behold, the fan started running! So then I tested the voltages of all the motherboard wires, and they were all good. Not perfect, but within tolerances. So, it wasn't the PSU.
I've now boiled it down to my mobo, CPU, or RAM. But, because the computer wont even post, no fans will even *try* to run, I figure it's the mobo or cpu. Is there any way to tell without me finding a working computer with compatible parts (there aren't any around where I am...). I figured the light on the mobo might be enough, or some other thing I'm overlooking.
Ram: OCZ Reaper 2x2GB OCZ3RPR1600C8LV4GK
PSU: CORSAIR CMPSU-520HX
Mobo: ASUS P7P55D PRO
CPU: Intel Core i7-870 Lynnfield 2.93GHz
Thank you... I hope you can help! Both are under warranty, but I don't want to have to try to replace both, mail them in, have them tell me they're ok, etc...
