Everything open on my computer, stops responding, task manager wont open, and my pc wont turn off unless I hold down the power

[SgtMaxx]

I wasnt sure where I should have put this... but here will have to work.

So as you guessed.. I have windows 7.
moving on.

A little background.
I recently factory restored my computer for issues that are now resolved..
This was 5 days ago. Everything was going great. Everything was running smoothly... Untill today.

Always around an hour... hour and a half, since I booted my computer up, I am unable to click on anything.. except the icons in my task bar, but clicking them does nothing. After about 30 seconds of that everything just becomes a blank page and im unable to change tabs. I try using task manager but Ctrl-Alt-Delete doesnt work. I tried opening task manager in advanced, but it just turns blank aswell.
I then have to manually turn off my computer using the power button..
Please
Help me.

Try booting Windows in safe mode and see if you can open stuff.

There might be a OS failure, Like Coodrow said, You should try it.

If the problem still persists, Reinstall Windows or repair it.
