My girlfriend's computer recently updated it's windows, and now get's stuck in a boot loop whenever it shuts down.
Oddly, the PC turns on but the CPU fans and pump (water cooler) don't turn on. The MOBO codes flash by until it hits "32", then turns off immediately and reboots. It then just sits in this cycle.
If I remove either of the RAM chips, the PC will then boot fine. After this, I can then shut it down and plug the RAM back in, and boot fine too (with both chips installed). However, if I then shutdown a third time and try to boot, It's back to the 32 boot loop.
I've tested the RAM overnight with Memtest without issue, I've even tried upping the RAM voltage to 1.65 while simultaneously underclocking it. I've also tried underclocking the CPU, disabling turboboost, and setting the CPU to a known-good voltage (I extensively overclocked/tested this PC when I built it 2 years ago).
I feel as if I've ruled out a hardware issue, but I don't know what I can do to fix the problem, as the BIOS seems fine as well. It really seems to be a windows issue, but it's not giving me any errors or BSOD to get a "hunch" to work on.
Any ideas? About to run a sfc. I haven't used the start-up repair yet, but I'm concerned as the start-up repair takes place after a boot, and I fear possible OS corruption if it gets in a boot loop during the process.
