Graphics issue followed by major slow down

[Zebedeeboing]

Hi and thank you for taking the time to read and possibly help! 

 

I have just experienced a major graphics issue that has now turned into a major slow down on my PC. 

 

I was running oculus rift creating a 3d model, then tried to render the model in a 3d printing slicer. The graphics crashed and everything went blurry with sharp lines running down parts of the screen. I restarted but no effect, it was even present in bios. I left it for a while but still no luck. 

 

I then swapped around some spare graphics cards and thankfully it just stopped blurring (woot..) but then I get into windows and everything is running incredibly slowly, even the mouse movement stops and starts. 

 

ANY help appreciated. Specs wise I'm running a 7700k, 1070, 16gb ram. 

 

Thank you.

Sorry, when I said slow, I mean unusable kind of slow.

are you sure that its gpu causing this issue? have you monitored your cpu usage?

It seemed graphics card related previously. I don't think it is now. Cpu usage is not above normal. 

 

I just tried a system restore from a few days ago and it failed to do it... Said that antivirus was causing an issue. I closed the antivirus but it still failed.

I reinstalled Windows.. Which took an inordinate amount of time. Seems to have worked, I can only assume that a file got corrupted somewhere that windows could not detect. Still a little worried about the underlying cause of the issue, that there may be something wrong with my graphics card, pcie lanes or other that caused a cascade of nonsense and a loss of an evening's work. 

 

Any suggestions would be appreciated!
