Hello, recently I have been having issues with a game that I play, Rocket League, where my CPU usage would shoot up to 100% whenever playing causing lag and what not. Now the problem has gotten much more serious... It started when my PC crashed entirely, whole thing froze and wouldn't turn off regularly. So I held the power button for a few seconds and it finally shut off. When trying to reboot it showed the usual picture advertising my motherboard instead of the usual Windows start up but this time it got stuck on that start screen. I waited around 7 minutes before it finally booted. (Usual Boot time is less than 10 seconds) Now, a day later, random programs are crashing, some processes take forever to load, and in general my computer is not functioning. As i am writing this message my taskbar is gone because I tried to open the "this PC" folder and that crashed. So now my taskbar has dissappeared and the only thing working is Google Chrome and Teamspeak 3. I need help diagnosing the issue, and solving it. Windows 8.1 by the way. Update: When I open my this PC folder now, my hard drive no longer displays the space it has left on it like my SSD does. This is what it looks like - https://gyazo.com/7b55e09d4265ac4cc518d91a94960134 . When I click on the hard drive to open it up, the folder crashes.
