I'm completely at my wits' end with my PC that's consistently crashing due to BSODs (codes like IRQL_NOT_LESS_OR_EQUAL and hypervisor errors). It initially started crashing randomly, then Windows got corrupted. After trying to get it diagnosed at a repair shop, they discovered one faulty RAM stick and suspected the GPU was also problematic. They reported that the system kept crashing even with the faulty parts removed, leading to the suspicion of a motherboard issue.
I've since replaced major components:
- Motherboard (MSI Z790 GAMING PLUS WIFI)
- RAM (new 2x16GB DDR5 kit)
- GPU (brand new Radeon 7900XT)
The only major part that hasn't been replaced is the CPU (Intel i7-14700k). I haven't altered any BIOS settings and even updated the BIOS to the latest version. Now, the system crashes while attempting to install Windows 11 from a freshly made USB—this happens during the install, often around 30% to 60% of the way, leading to BSODs and reboots.
I've ensured that there's minimal hardware connected and tried a fresh Windows USB made on another PC. Windows sets up the EFI/MSR/primary partitions but never manages to complete the installation. Interestingly, the original motherboard had a couple of bent socket pins, and this CPU was used during the period of issues.
Could a damaged CPU memory controller be the culprit here? I'm looking for any advice or insight before I consider replacing the CPU as a last resort!

You know, it might be the CPU, but also consider if you have an old hard disk lying around. It could help rule out your current disk as the issue. Maybe ask a friend if they have one you can borrow?
This reminds me of an issue I had with my 8600K. The BSODs turned out to be signs of a failing PSU. Changing it out resolved everything for me, so you might want to look at the power supply too.
I can sympathize with your situation. If I were in your shoes, I would be swapping out the SSD next, then the CPU. Especially if the 14700k is one of the early units.
I had similar problems because of a faulty hard drive. Once I swapped it out, everything was running smoothly. If you haven’t tried that yet, it might be worth investigating.
It sounds like the CPU might be where the problem lies, especially given the issues you've had with the 13th and 14th gen Intel processors. Could be bad micro-code, which would definitely warrant an RMA. Also, did this issue occur on the same SSD throughout? A faulty SSD could also be a possibility.
Definitely sounds like the 14700k could be the main problem here. I had a mate who faced something similar, and his CPU turned out to be faulty.
Yeah, since the CPU was in there during all the BSODs, it makes sense it's a suspect. I feel for you; you’ve replaced almost everything else! But SSD issues can be tricky, so keep that in mind too.
