your computer shuts down after a short period of operation
I once decided it was time to upgrade my PC, which worked until I received a new CPU (RYZEN 5 5600X) that didn’t fit my motherboard. I replaced the board, but it still didn’t function properly. After flashing a BIOS update, the issue persisted, so I switched to a different motherboard. I then purchased an MSI B450 TOMAHAWK MAX II, hoping it would work with the AMD RYZEN 5 5600X without a BIOS update. Although I updated my BIOS, the system would only power on briefly before restarting. I’ve also tested various RAM sticks, a new power supply, and even tried using an older CPU (AMD RYZEN 5 1600) in my PC, but it still had the same behavior. I’m considering asking a friend who has a Ryzen 5 5600X if they can test it in my setup to determine if the problem lies with the CPU or the motherboard. In the end, I suspect the issue might be related to motherboard compatibility or a faulty CPU, but I’d appreciate your advice.
Based on your description it appears the CPU might be the issue. I experienced a similar problem with my 3600X where the screen went blank and fans increased unexpectedly. After replacing the processor it functioned properly. The motherboard compatibility list confirms it works, and the latest BIOS should support it. You could test with minimal hardware—just CPU, one RAM stick, graphics card, and no additional drives—to verify. If the behavior persists, consider swapping the processor or having a friend try it to confirm.
During the brief periods when it functions, can you verify the temperatures to prevent overheating? Also, what power supply unit do you have? Would it be possible to use another PSU to test and eliminate this possibility? Trying the CPU in a different configuration is also a helpful approach to pinpoint the problem.
