Can I delete my GPU if it's dead

My laptop overheated and since then it's been really slow, so I've been told it was from my gpu being dead which is making my CPU bot as good. I'm going to uninstall all of my GPU stuff, but will that damage anything. Maybe something is important that i should keep? I have a nvidia GeForce 520m 1gb and an intel core i3, not very good I know 🙁
 
If it's an Optimus lappie, you can have everything use the on board GFX which it should default to.

If the GPU fan spinning ?

Is the insides and heat sinks clogged with dog hair, cookie crumbs and such ?
 
My computer is fine now, I started it up then ran CHKDSK now it's faster. But during CHKDSK it came up with many "File unreadable" errors. But earlier I was doing a disk defragment but it froze so I held the power button, that may have done it.
