I built my gaming PC last December, and for about 8 months it was working fine. Recently, it started crashing unexpectedly. The crashing behavior varies: sometimes it completely shuts off and won't turn back on, other times it keeps trying to reboot but fails, and sometimes everything stays powered on but with no boot. The keyboard and monitors lose signal, showing no display while the RGB lights on the keyboard are off. On good days, I can use it for a while, but on bad days, it crashes within minutes. I've tried a lot to troubleshoot: removed the GPU (but the problem persists), updated BIOS, tested different RAM sticks, and checked all cable connections. I completely disassembled and reassembled the build, and removed unnecessary USB devices, but nothing has helped. I even replaced the CPU after sending it in for testing, and I sent the motherboard in for diagnosis but they found no issues. I swapped out the power supply cable too, but the crashes continue. I really need a functioning computer to start my Master thesis. Any ideas what could be wrong?

This sounds a lot like it could be a RAM issue. One of your RAM sticks might be failing, causing repeated memory testing failures. Even if you've tested different sticks, it’s worth checking if there's any compatibility issue or trying them one at a time.
Did you replace the thermal paste when you swapped the CPU? Also, has the power supply unit (PSU) ever been tested with a PSU tester? Sometimes issues can stem from there. It's also worth checking the PSU output if you haven’t done that yet.
