HELP, PC is Unresponsive

[BlessedNoob]

So yesterday I was playing shadow of mordor for about 30mins and then i had to go to work. After 4 hours of working and got home i went to play my game. this time my PC took about 5mins to boot and when i clock on a taskbar app i get an endless hourglass. I hit restart and then got an endless please wait, so i had to force shutdown. When it booted again, i waited a few more minutes for my startup programs to launch. Steam opened up and when i hit 'run' for Shadow of Morder it said 'Runnning' and the window popped up but nothing happened. then i hit run on Batman: Arkham Knight and it also said 'Running.' I had about 4 games saying 'Running' until i decided to restart and got the endless 'please wait' icon. I gave up and about 18 hours of letting my pc stay off i figured it might work, nope. This time only Google Chrome opened up, a couldnt get any apps to start, not even task manager. So i did some looking and it might be Malware, but i didnt pirate anything. im in the process of system restore, its been Restoring files for about 10mins now. Hoping it get better.
Help please

Let us know if system restore helped...

Also, run a scan of the computer to see if you got hit by anything

it's finalizing file restore finally. before the system restore, i tried to download malwarebytes and it just froze on the setup and couldn't exit or anything, and i downloaded avast and when i hit open when done, nothing happened either

Update: it finished and did POST. what is things still dont launch or are unresponsive? what should i do?

Update: everything booted normally, startup programs started, which i disabled now. Steam opened up fine, task manager works, havent tried running a game yet. Will do so now and hope it works
