I was following a blender tutorial about a week ago and my new RX 5700 XT was crashing the application. I decided to throw my old graphics card in with it (RX 580) to see if the application would stabilize when I used a different GPU. I shutdown the system removed the RX 580 and powered it back up and my system ran about 90% slower. I looked at task manager and it seems that the processor (Ryzen 5 2600x) was stuck at .54GHz even under a load. I decided to go into BIOS and look at the voltages and it had a stable .808 which is normal at idle. Then I rebooted and it was back to 3.9GHz and adjusting for load. I decided to reboot once more to see if it was fixed and it went back to .054 GHz. I have to enter the BIOS and exit to get it to boot at the right speeds, of which i have done repeatedly with success every time. Also, it seems that after long periods of being powered off i.e overnight, it will not POST properly and I have to shut it down and restart twice. My system will also not output HDMI anymore. I can only get into BIOS with Displayport. My Board is a MSI B450 Gaming plus. I had to RMA it when I bought it new and the refurbish worked fine until now albeit it came with a bent power led pin. I'm thinking of buying a new board from a different manufacturer. Before I do I want to make sure this is a board issue and not a Processor issue. Any ideas?
