Well gpu shouldn't crash if there is no driver install since it will be off.

Maybe your driver isn't properly uninstall.
Try complete uninstall driver with "display driver uninstaller (DDU)" in...

Try not to run furmark if not adviced. Furmark is known to fry a lot of GPUs (including the healthy one)

What do you mean by can't install it? Does it give error or something?
Basically give more details about problem.

Yes since gt610 is the lowend one (actually the lowest of the same gen)

By searching with google, which lead to many sites with benchmark and people with similar question, I found that Intel HD 4000 is better than gt610. And intel hd 4600 is better than intel hd 4000....

If you're on build 10074 you can just type

DISM /Online /Cleanup-Image /RestoreHealth
