PC slows to a crawl until rebooted, seemingly at random.
This has been going on for about a week now and I don't understand what it is. Sometimes when I start the computer, log in, or sometimes just out of nowhere it just becomes unresponsive and I can't really do anything. Task manager, start menu, and anything else take minutes to load up. I've ran all kinds of tests, all of which passed, as well as formatting and reinstalling windows. I also have a 6 hour long test running right now called Hot CPU Tester Pro 4.
I'm at my wit's end. I don't recall changing anything that should have begun these crashes. I upgraded my CPU and PSU recently, but everything had been working great after I installed them. I thought it may have been updating my nvidia driver, but I went back to the previous driver and it's happening just the same.
Any ideas? I've tested the HDD, memory, and CPU multiple times so far with all tests passed. I don't know what else to do, or even WHAT is causing the issue to begin with.
