Hello,

I have recently built a new PC, it's not the first one I build and the others worked fine. I installed Windows 10 and it worked well for about a week than it did its first blue screen. After a restart it worked well for another 2-3 days. Then again, a blue screen. After that, every time I restart the PC, a blue screen happens after a minute or so after the login, then blue screen in the login screen, then blue screen in the windows loading screen.

The blue screens I received were varied, "IRQL_NOT_LESS_OR_EQUAL", "System Thread Exception Not Handled", "Page fault in non-paged area", "MEMORY MANAGEMENT", "KMODE_EXCEPTION_NOT_HANDLED" or hexa code without description, but the first three were those who happen the most.

I tried many things, I don't remember the exact order, but I ended up formatting the SSD and removing everything from the motherboard, but nothing worked. I made my PC analyzed and they said it was most likely a defect motherboard. So I did an RMA on it and they sent me a new one. Now I still have the same problem with the new one.

I tested with a minimal build, the motherboard, the processor, the watercooling fan, 1 slot of RAM, the power supply, the screen and a keyboard, not even the connector of the case or any hard drive/SSD, so I had to push the power button directly on the motherboard. Still the same problem.

I tried with a windows 10 on a USB key and a windows 7 on a CD and they both do the same kind of error if not the exact same. The further I went in the installation process was with Windows 10, I succeeded to begin the installation on the SSD, but at the first restart during the installation, it crashed again.

The only pieces that could still cause a problem and that I can't test nor replace are the processor, the power supply, and the CPU water cooler. Do I ask an RMA on the processor or do you guys have any other ideas?

I did a memtest86 5.01 on one of the RAM card and 0 errors

I tried Ultimate Boot CD. On the Mersenne Prime Test V28.5, I got 2 errors. One while running the diagnostic (the full one or the lite) that said "fatal error : Rounding was 0.5, expected less than 0.4" and one at the very launch of the Prime Test application. I tried adjusting the RAM and the CPU clocking and voltage without good results.

A friend of mine suggested loosening the motherboard and the CPU, I tried but nothing changed.

My build :

  • Motherboard : ASUS Z170-DELUXE Socket 1151 Intel Z170 Chipset
    Processor : Intel Core i7-6700K 8M Skylake Quad-Core 4.0 GHz LGA 1151 91W BX80662I76700K Desktop Processor Intel® HD Graphics 530
    Power supply : EVGA Supernova 850 P2 80 Plus Platinum, 850W Eco Mode Fully Modular
    Case (tried without any connection to the case) : Corsair Graphite Series 760T Black Steel / Plastic ATX Full Tower Windowed Gaming Case with two 140mm Red LED fans
    DVD player (Tried without) : LG (WH16NS40) Internal 16x Blu-ray Writer
    RAM (Tried each one individually) :G.SKILL Ripjaws 4 Series 32GB (4 x 8GB) 288-Pin DDR4 SDRAM DDR4 3000 (PC4 24000) Desktop Memory Model F4-3000C15Q-32GRK
    CPU Cooling : Cooler Master Nepton 280L Ultra High Performance Closed-Loop Water Cooler
    Graphic card (Tried without) : VGA EVGA|06G-P4-4995-KR GTX980 TI R
    SSD (Tried without) : Samsung 850 pro

Thank you!

Very odd indeed, its entirely possible the cpu is responsible, highly unlikely the cooler is since nothing throws up any flags on that front, and the psu seems OK. CPU failures do happen, but not very often. And it seems like you've put a ton of time in trying to figure out the problem already. I'm almost hesitant to say to return the cpu at this point. But it's one of 2 things you haven't returned, and it seems like the only culprit going by what info you've posted.

I'm gonna bump this, I don't really have any inclination to what could be causing this, and it's a shame to receive no help here after all you've been through already. I'm gonna sit on this one.

I contacted Intel and they sent me a new processor. After a week of use, it works fine and I don't have any BSOD. So the problem was a defect processor.
Thank you!
