I've been having a lot of display issues recently. I often have my display freeze and become covered in random green squares and black outlines before it resets with a message about my display driver recovering. I updated the drivers and saw no change. I have recently gotten bluescreens and seen these green squares even on the BIOS screen, which to my understanding rules out it being a software problem. These problems went away for a time when I turned on debug mode in the Nvidia control panel, as google suggested might help, but they have returned now. I've run memtestcl and it returns 0 errors, but the tests take much longer to complete than they used to. https://i.imgur.com/tc5UvB0.png. As you can see, there are several tests which take upwards of 500ms to complete when previously, none took more than 50ms. However, if I run memtestcl while I have a game running in the background, the tests are very fast. I have never experienced these display problems while a game was running or while running Furmark(though often they will occur immediately after I close the game). My temps are fine, from what I can tell: MSI Afterburner has never returned a temp over 65 C under load and it idles in the mid 20s. I dusted my computer and checked all the connections and saw no change.
There is another problem I have had essentially since I built this PC. My computer only worked properly 1 out of every 2 times I started it, alternating. If I started it, my display would have terrible stuttering and it would refuse to recognize USB ports at random. If I restarted it, these problems disappeared. If I shut it down and started it again, they would return. This was fully predictable. Due to my own laziness, I never bothered finding out why this happened. But now I notice that, on the bad restarts, I get the display problems immediately on the BIOS screen and they persist(without the display driver resetting), Afterburner does not recognize that I have a video card installed, and it will not recognize any USB connections other than mouse and keyboard(which fails to actually type randomly). Is it possible that this is actually a problem with some other part of my computer, that is also causing my video card issues? Or is that just wishful thinking in a time of overpriced GPUs that I don't want to have to pay for? Or do I just have more than one problem?
