I recently put together several upgrades. 3700X to 5900X, ROG Strix Gaming B550-F motherboard, Corsair 750TVX psu, AMD 6750XT, 2x16GB Corsair Vengeance ram. Upgraded from stock AMD cooling to the Thermanlright Peerless Assassin and added more case fans too.
However, this machine constantly shuts down. Sometimes within 5 minutes. Sometimes it can go hours. I tried updating the BIOS, changing to my old 5700XT video card, putting in a Corsair 850w psu. Never had this issue on my old system.
I can run 3dMark and watch temps, everything seems within ranges. Not even throttling levels. It is random. Event viewer shows nothing. My last resort is to try another mobo from another brand...or do a full wipe and reinstall of Windows.
