In games (tried multiple, not only 1), sometimes (most of the time after 20 mins of playing) the game would just freeze. Sound would still work. I would only have one tab of reddit and nothing else running (8gb ram). I would sometimes be able to alt-tab, sometimes not, so I often just ctrl-alt-del then access desktop. I would be able see the taskbar at the bottom, as well as start programs, but the almost the entire screen (other then taskbar) would be black. So, I could hover from taskbar to check task manager and speccy (but couldn't find any problems), but would not show up on the screen that is black. I can also close everything from taskbar except for the game I was in. Since I have no idea what this is or how to deal with it, I always re-start my computer. It is annoying having to do this several times a day for a few weeks. I can send specific specs if relevant but I built my pc w/ my father almost a year ago w/ pretty damn good components. Also first time ever on this site nor do I know much about computers, so do not know which category this falls into...
