I just installed a bunch of games I got for Christmas but still have plenty of hard drive space free. When I was playing one I minimized it to check a tip online and when I got back into it the game kind of stuttered and then froze. When I restarted I could hear the PC startup but the monitor was acting like nothing was plugged in. I tried restarting and nothing showed up still.
After I turned it off for a while and turned it back on it started working again. This same thing has happened a few more times and with different games. If I'm just browsing the internet or watching videos my PC works fine. I tried the built it windows disk check and it says everything is ok.
