While I am a complete n00b to these (and all) forums, I am an experienced system builder, so I know the basics (like making sure x plug is fully inserted, etc.). Sorry for the TLDR, I'm new to forums.
However, I cannot seem to diagnose an issue I am having with my rig.It runs windows 7 pro64
Before I get to the issue, here is my rig:
Gigabyte H67mA-USB3-B3
Intel Core i5 2500k (not OC)
Corsair TX750M
EVGA GTX560se
EVGA 8800GT (for extra monitors)
Wintec AMPO ram (8GB)
Kingston HyperX black (8GB)
There is also two hard-drives (a WD black 1TB and green 3TB) and a CD/DVD drive.
The issue started a year or two back where the system would start, run, and after a while would just freeze with fans ramping to full speed. This turned out to be a bad PSU (Main rail failure, but it was a quality brand).
I replaced the PSU with the one that it has now, and it ran perfectly fine for a while. Then, every now and then, the system would not turn on after being turned off unless the CMOS was cleared. It would also BSOD upon awakening from S5 sleep. I tried replacing the battery, per gigabytes instructions, to no avail. I RMA'd the board, ant it worked fine afterwards.
TL;DR
Now it is a constant problem, the system will not start after being turned off unless I fiddle with it for roughly 30min. I have tested the case switch, tried shorting the power button pins, tried clearing CMOS, GPU removed, new CMOS battery, and the PSU is just fine. There are no shorts on the back of the mobo, and I've dusted the system.
Just today it stopped powering up at all unless I jump the main 24 pin connector real quick with everything plugged in, and then power it on again. It at least keeps time now though.
I don't have the money for a new rig, and LGA1155 mobo's have gotten expensive. It this something I can fix via hardware reconfig/part replacement or is it a problem within a chip and I'm just SOL?
