I've had this PC for just over 3 years now and it generally worked without a hitch.
i5 4670k
Asrock Z87m Extreme 4
GTX 760
8GB RAM (one stick)
Cooler Master gx750
In September I went off to Uni and left my PC at home and when I returned it just wouldn't start. The fans would spin up, the LEDs switched on but that's as far as it got. No boot. Strangely the period for which the fans come on for is variable. One time it will be less than a second, the next it's up to a minute before it turns off and tries to start again.
In January, I decided to bite the bullet and buy a new PSU which I thought was the most likely culprit. Installed it and there was no change. No boot and the exact same behaviour. Cleared the CMOS and breadboarded the motherboard and still no start. I then reseated the CPU and after a few attempts at starting it the PC eventually booted. I chalked this up to a coincidence.
However, it still showed the same behaviour with it only occasionally booting. As I type this on my laptop I can hear my PC fans start for ~1 second and then shut off again, no hard drives spinning up, no nothing.
Oddly, when it does work and I want to shut it down, it doesn't fully power off and I have to hold the power button completely switch it off.
I think it's unlikely that I got 2 faulty PSUs in a row so I think I can safely rule that out. The only other thing I can see being the problem is the motherboard. Any ideas?
