Hi,
Posting here for troubleshooting help as I'm really struggling to work out what to do here.
I wanted to upgrade my old Intel CPU, which was also on a motherboard using DDR3 ram. So I purchased a new Ryzen 3600x, an MSI Tomahawk Max and some memory 2x8gb DDR4.
Added these parts in and the computer worked perfectly for about 2 weeks. Then it some point, the display cut out (fans still running, no signal to monitors). Then the PC would not POST on attempting to turn it on (all fans and the mobo RGB lights would turn on, no display output).
I reseated everything a few times with the same outcome to same result. Switched back to all my old mobo/CPU/memory combo and they worked fine. This confirmed my GPU, hard drive and PSU were fine.
Also tested with each RAM stick individually with same result. I'm guessing it's extremely unlikely for both RAM sticks to have failed. Also attempted CMOS clear and BIOS flashes.
Debug lights would appear on motherboard in normal sequence when computer was turned on, but then debug lights would all turn off fairly quickly. Given the CPU light was not on, and mobos are more prone to failure, I RMA'd the motherboard.
Encountered the same issue on the replacement, so got a new CPU. Worked for about 10 minutes. Now the computer reboots automatically on the blue windows logo start-up screen - a constant boot loop. Trying to boot anything else off a USB also reboots after a few moments and then loops.
Putting the old Intel mobo/cpu/ram combo back in still works. I have since also tried a new PSU with all of the same results.
Any ideas what I should do? I've tried 2 CPUs (both Ryzen 3600x), 2 mobos (both MSI B450 Tomahawk Max) and 2 ram sticks (both Corsair Vengenance LPX 8GB DDR4). I don't know whether a part is broken or there is some basic incompatibility issue between any of them. All of them were purchased new within the last month (from different stores), I don't know what I should be RMA'ing and I can't go to a computer shop for help during the lockdown.
Any advice would be appreciated. What fixes should I go through / parts should I contact customer support for.
Thanks
