Hello people of the internets ;>

I've got this issue which started way back in November I think.
So there I was, switching CPU cooler and everything was fine. I started the system but it wouldn't get to BIOS. Error thingy on my AsRock P67 Pro3 told me that it's ram related so I switched slots from 1 | 3 to 2 | 4. Didn't help so I put them in 3 | 4 and boom, it worked. My guess was that the pins of the CPU socket on mobo are bent, and they were. So far I didn't see any more problems so I continued using system while I figure out whether to fix the pins or buy a new mobo.

After a while problems with GPU started, it would overheat like crazy. We're talking 70C idle, 98C in AC3. Took my GPU and tested it in my friend's setup. Temps were fine so I figured - ok, it's the mobo (bent pins and all that). Bought new motherboard and this is where things get weird.

The day I was supposed to replace mobo my PC started, I got to the desktop and it died with a GPU drivers related BSOD. Tried reinstalling, all that stuff but it didn't work so I decided to replace the mobo since I was supposed to do so anyway.

Replaced and of course, relocated the RAM to 1 | 3 but apparently it wouldn't boot.
The problem is still there. As to GPU, tried few things, even formated and started the system from scratch (was about to do so anyway) and as soon as I install any drivers I get a BSOD.

I'm sending my GPU to the manufacturer for RMA today but the problem with sockets is still there.
The question is - could it be PSU screwing with the whole system, not delivering power to, for instance - 2 first ram sockets or could it be CPU related?

There was a theory where people said that maybe there's some thermal paste on the bottom side of the CPU but there isnt any. Only on the top and a little bit stuck on the sides. Besides that, CPU is doing extremely fine. 22C idle on average.

I'd appreciate any response. Thanks upfront ;)

EDIT: Solved.

Please post additional information.

CPU - brand and model
CPU cooler - brand and model
GPU - brand and model
PSU - brand and model
Case - brand and model
RAM - brand and model

We know only the motherboard is ASrock P67 Pro3. I got one of them, but I haven't experienced or head of similar issues with this model of boards.

i5-2500K, Antec TP-750, EVGA GTX580 SC, Patriot G2 2x8GB 1600MHz. Dunno how the case and cooler are related but SilentiumPC Pilum 400 and Zalman CNPS10X Flex.

EDIT: Just came home. As to mobo, I had AsRock P67 Pro3 and replaced it with the same model so I guess that it's not mobo related. I will probably be able to test PSU as well as CPU this week but if it's possible I'd like to know which part is most likely to cause that kind of damage. CPU or PSU?

PSU was fine till the part where (after the first 2 sockets dropped dead) while playing AC3 my screen would go black and GPU fan would go crazy up to 100% . Now it could be the PSU problem but it can be a GPU problem as well which, I just sent to EVGA for RMA cuz of the drivers.
CPU is fine. It has some paste on the sides but I don't think that it would cause such problems. I thought that it had some on the bottom but nope, it's clean. CPU temps are around 22-26C in idle so in my opinion CPU is ok.

Now my theory is that there's something wrong with PSU and it's basically screwing with both mobo and GPU. I'd like to hear few more opinions since last time I thought that I know what's damaged I bought new mobo which in fact is not the problem.

Thanks again ;)

Update.

I finally been able to test the system today. I went to a buddy of mine with my CPU, 2 motherboards (both AsRock P67 Pro3) and my RAM sticks.

Before I describe the combinations though - once the 670 arrived (there was a problem with BSODs 0x00116 so I RMA'd the GPU) I tested the setup and RAM slots which were dead switched from 1 and 2 to 3 and 4. Now the dead ones are the 3rd and 4th. My conclusion was that since the 670 requires less power (had 580 before that) - PSU might be the case, you know - less power needed so it somehow switched the slots but well.... as you can see below, it isn't.

We tested the following combinations.
My old AsRock P67 Pro3 (without bent pins), my RAM, my CPU with my friend's GPU (670 as well) and PSU (600W, don't remember the brand) - the ram slots 3 and 4 are dead, error 55 shows up.
My old AsRock P67 Pro3, my RAM, his CPU (i5 2500k, basically the same CPU), his GPU, his PSU - error 55.
My mobo, his RAM, his CPU, his GPU, his PSU - error 55.
His mobo (Asus P8H67-M Pro), his RAM, my CPU, his GPU, his PSU - no error.
His mobo, my RAM, my CPU, his GPU, his PSU - no error.

So the error occurs with my mobo. Which makes no sense since it occurs with the mobo I used 2 years ago, the one with bent pins and the brand new I just bought as well. All 3 of them are AsRock P67 Pro3.

I... i don't know what's wrong at this point. Help... please...
