Hello,

I have built my pc over 2 years ago

Specs:

Asus Maximus V Formula
Intel Core i7 3770k with an Corsair H100i
Corsair Vengeance 32GB 1600Mhz
MSI GTX770 4GB Edition
Cooler Master Silent Pro Hybrid
Aerocool xPredator Black Edition Case

Everything was working fine until I left my pc unattended for a few hours, and came back to see that done of the displays were working. I reset the PC and saw that it was still not working. I saw an error code 55, which indicates "Memory not installed". I switched the memory and different slots, but nothing worked.

I kind of gave up and decided to RMA my motherboard. The RMA wasn't accepted by Asus (long story) so I had to buy a new motherboard. The next problem was that the motherboard I had is discontinued and not sold anymore. I ended up buying the Asus P8Z77 WS motherboard.

When that came in, I first build a testbed, so see if everything was working, which it was (hoorayy). I then built everything into the case again, Windows 8.1 restored itself somehow after a mobo change and everything was fine.

A few days later, (yesterday, 2nd of September) I left my PC unattended for about half an hour again. When I came back I again had no display output, on neither of my two displays. I freaked out, and hit the restart button. Surprisingly that worked.

It booted perfectly fine and was working like a charm again. Until earlier today.

I was messing around with Virtual DJ, and my PC decided to randomly reboot on me. It rebooted fine and worked again, but I began to fear that there still was a problem unsolved. After some time, it rebooted again, and this is where the horror begins. It started to reboot everytime it booted succesfully into Windows, after like 5 minutes.

I decided to reset the UEFI, which made no difference. When I booted back into the UEFI, it froze on me, with an Q-Code A2. I disconnected every SATA device, exept for a new SSD, to try and install windows (in hopes that the SSD was broken somehow). And everysince then I suffer from the Q-Code 55 again.

I borrowed a PSU-tester, and everything seems fine to me. All voltages are showing and are above the rated output.

Again, I have tried to mix the DIMMs and slots, and none of them seem to work. The GPU turns on, but the H100i (liquid cooling) does not, and the CPU doesn't get warm.

I am completely lost here, help would be extremely appreciated

Best regards,
Ivo

Are you securely putting the power supply leads in firmly ? if not then that could be it. Also It sounds more like a RAM issue, remove the RAM completely and if your computer hits bios then thats your problem. If not then it is something to do with your PSU. Whether its being faulty or a bad make.

This link might help seeing if your PSU is the problem just by which one you bought, http://www.tomshardware.co.uk/answers/id-1804779/power-supply-unit-tier-list.html

Good Luck, if this is enough, put as solution so people know its solved.

I forgot to say that I sleeved my 24pin and 8pin cables, but the problem occured before I did that. I am pretty sure I put the power supply leads in correctly. May I ask why you think the problem is related to the PSU? Because that's what I've been thinking but everybody I ask tells me I am nuts and that a RAM problem is not related to the PSU.

Thanks

Unsleeve, might make a difference. Also they can be indirectly, if you surge a board it can kill RAM, so it can be linked but that doesn't matter in your case. It sounds like a power cut or it's slipping and the board will just kill power to protect components.
