This has been happening for about two months now, and it's been getting worse and worse.
I really don't have the money to fork out to get it checked up on (That and if I tried getting my parents to pay for it my dad would call it a 'waste of time')
Been having these type of issues as shown below: Red and green flickers on screen in dark areas of games like Bioshock Remastered, 'spiky' textures.
We've tried doing a clean restart of the computer, reinstalling graphics drivers, fiddling around with its settings, reseating it, cleaning the computer.
Nvidia Geforce GTX 970
Intel i7-4790K Processor
Naturally, this isn't my own PC, this was my sisters before she moved.
So I don't have the list of specs down, nor have I been able to find exactly what they are, so the rest are a uh, mystery ;-;
Please. Help ;-;
