Hi Batfink,
It is certainly outside of the remit of the forum as it is most unlikely to be malware associated.
My best guess would be a fault in the graphics set-up. If you have a separate graphics card and you know your way around the inside of a PC then I would remove the card and then reseat it.
In the unlikely event that it is software related then try a system restore to before the start of the problem.
Sorry I can not help further but you could try PCPitstop for further assistance
