So, I changed my ram speed in my BIOS cause it was absolutely terrible. I ran Userbenchmark test, and my ram showed really bad performance. So I went into the BIOS, and changed into something called XMP, and ran the test again. My ram showed way better performance, but now I can't click the little windows icon, or the search icon bottom left (windows 10) and I can't press the windows key on my keyboard, and I can't press windows+tab or anything. But Explorer.exe works fine.
These are the buttons I refer to. I can't get the windows menu, after changing my BIOS settings... Like my ram work better than ever now, according to the test, but now windows is f'ed up. Please help me
