Been having hardware problems recently. I thinking my problem is a Dead motherboard and possibly power supply.
Specs :
CPU - Intel i3 2120
Mobo - Asus P8Z68-V Gen3
RAM - Crucial Ballistic Low profile 2x4Gb 1600mhz
GPU - XFX 6870
PSU - Corsair Tx750W
Around 4.5 - 5yrs old
Problem :
When running heavy loads ( in this case fallout 4 ) my pc would completely shutdown with no warning and power back up a few seconds later. There was 1 time it would get stuck in a boot and restart loop until I hit the restart bottom.
Initially I thought it was power failure or overheating. CPU temps were around 50-60 degrees and GPU temps around 80 degrees playing games. Thinking it was then psu was overheating I cleaned it out with a compressed air can. The problem still persisted.
I had a look at the voltages in the bios. They were about 1% out I.e 12.096V was being drawn from the 12V rail. Using Hwinfo ( Sensor monitoring software ) the voltages stayed around the same with some 1% drops. Not sure how accurate these are as I've read the only sure way is to use a voltmeter but I don't have the means available.
However during checking the voltage under load I had a power cut. Now when I boot the machine it doesn't post and the VGA red light on the motherboard stays lit. Normally this signifies a problem with the GPU. However the same thing happens if I remove the GPU and all other PCI cards.
I removed everything and began to work through each component. With just the CPU I get the correct error code for no ram. With RAM (Ive tried 2 different sets) the VGA lights up. After this I tried clearing the CMOS by shorting the jumper and then removing the battery for 1 hr. Neither worked.
Power cuts are quiet frequent here. Around once a month as we use pay as you go electric and goes dead before refilled most of the time. I feel stupid now for not considering a surge protector.
At this point I'm asking to see if someone could think of something I've missed or to confirm it is the mobo or psu or both.
Thanks for your time.
