Sounds like a video card problem. Do you have another video card you put in to see if they work?

no i don't but everything worked fine a couple of days ago. and another problem is that i can't use system restore to a point where i did not have it,

 

Already used anti malwarebytes, ESET, ccleaner, ... to scan and clean register and deleted most unused programs it still keeps doing it.
