So long story short I bought a new GPU (gtx 970) after putting that into my machine and installing drivers my BIOS screen was taming like 40 secs to get past then PC would run fine (I also wasn't able to access to BIOS no keys would work). I did nothing about it untill seeing a post about taking the CMOS battery out for 2mins then putting it back in. Now my PC just shows the BIOS screen which I still can't enter then comes up with a black screen. The monitor is still on but screen just black.
I have tried everything I can think of, moving ram slots, taking out hdds moving GPU to another location but nothing changes. The mobo doesn't have onboard graphics so I can't try without the gpu.
Any ideas what this could be?
My mobo is the gigabyte x79 up4
