PC keeps freezing 2 minutes after boot
My PC has been randomly freezing for a while now and I still can’t figure it out.
Specs:
- i5-14600KF (recent upgrade from i5-12400F)
- MSI PRO B760M-P DDR4
- MSI RTX 5060 Inspire 2X OC
- 32GB Corsair Vengeance LPX DDR4 3200
- Corsair CX650 PSU
- Thermalright Peerless Assassin 120 SE
- Crucial P310 2TB NVMe
- Windows 11
Important:
The freezing actually started BEFORE the CPU upgrade when I still had the 12400F installed. The 14600KF upgrade did not fix it.
Current behaviour:
- PC freezes around 30 seconds to 2 minutes after boot
- Usually no BSOD anymore, just a total hard freeze
- Mouse/keyboard completely stop responding
- Earlier on I also got BSODs like:
- SYSTEM_SERVICE_EXCEPTION
- KERNEL_SECURITY_CHECK_FAILURE
- CRITICAL_PROCESS_DIED
- Sometimes Windows recovery/boot corruption too
Things I’ve already tried:
- Reinstalled Windows 4 times
- Updated BIOS to latest version
- Disabled XMP
- Tested different RAM
- Tested different PSU
- Tested different GPU
- Removed old cheap SSD completely
- Disabled all non-Microsoft services
- Reseated cables/components multiple times
- Windows Memory Diagnostic found no issues
- Has frozen in Safe Mode too
At this point the only major hardware I haven’t replaced is basically the motherboard.
Could this realistically be:
- faulty motherboard/chipset?
- M.2 slot issue?
- cooler/socket pressure?
- something else?
Trying to avoid blindly replacing parts.
