r7 5800x

Hello. I recently upgraded my CPU from a Ryzen 7 5700G to a Ryzen 7 5700X, and ever since then my PC has been stuttering doing standard computer tasks such as browsing, dragging tabs around, and music lagging when not in focus. I've tried to reinstall Windows, update BIOS, and even fully reset...

After installing my new r7 5800x I get a black screen after exiting bios. The fans and rgb ram are on and there is a white light on my mobo. R7 5800x Rx 6800 Msi b550-A pro 16 gb rgb trident 3600 When I put my old cpu on everything works fine. I downloaded the latest drivers etc for the mobo.
