PC stuck on Windows 7 welcome screen after uninstalling avast.

So I decided to uninstall avast yesterday since I already had AVG and didn’t think I’d need avast anymore.

Today when I came to start my pc up, it got stuck on the windows 7 welcome screen and occasionally flickered black.

I tried booting up into safe mode for a system restore but that didnt work either, I got the same problem.

I’m not sure how to go about fixing this, any help would be appreciated.

Thanks.

Anyone have any ideas?
