So I left my PC on idle, I built it around two years ago. Anyway I came back to random blue horizontal lines on my screen, I went to properties and found that my computer wasn't detect my GPU or monitor even though I got picture. I tried restarting and it came up with this.

I can also get to the windows desktop at times but my PC does not detect my GPU or Monitor

I'm not quite sure what to do I have tried it on another monitor and got the same screen. If someone could help me out that would be great cheers!

Specs:
i5-4570k
nVidia GTX 780
MSI Z87-G45
Corsair CX750M
12GB DDR3 (Took it out my old PC)

Are you overclocking at all? The Corsair (CX?) 750M is a lower quality unit and could have caused issues with your CPU and/or GPU. This sounds like a display driver issue and I would try booting from your mobo display with the GPU removed. If you are indeed overclocking your GPU please remove the overclock and try booting with the card installed.

No I haven't overclocked at all. I am reinstalling the drivers right now but I have seen that my PC doesn't detect my GPU or monitor yet I still get picture
