So I have a p5Q mobo, E6550(stock), crucial ram, PC p&c 350w PSU and a ati video card of some kind.
The PC began to become flaky and not posting randomly, then one day it wouldn't post at all. I replaced ALL the parts one at a time and it would post, then not post, then post, then not post seemingly random. It doesn't even care what parts it has in it.
So I went to the store and bought a new motherboard, cpu, psu,video card and ram. Now guess what...still won't post reliably. I've checked all the jumper settings, I've tried all kinds of ram configurations. I've tried literally everything I know how to do on PC's and that's saying a lot. THis is 100% new. The only old parts left are hard drives.(not important to posting) It won't post w/ or w/o the optical/hdds.
Also, just to clarify, by no post I mean the computer turns "on" but doesn't give the VGA beep nor display anything on the screen nor play the windows turn on sound after 2-3 minutes. The fans turn on.
If I take out the vid card I don't get a no vga beep, if I take out the RAM I DO get a no ram beep.
I'm completely stumped. It's like having a car transmission fail and you buy a new car only to find the new car's transmission is broken in EXACTLY the same way and it never had ANY interaction with the other vehicle.
I've measured BOTH the old and new PSU's rails with a voltmeter and they're all withing 1-2%. I've tried jumping the PW_Switch jumper instead of using the front button. I've tried booting outside of the case to eliminate possible shorts. I can't think of anything else to try.
Extremely frustrated.
