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.
