Multiple issues. Seeking advice.

Hi guys.

Right this issue started with my GPU every now and then just stopping to output to my displays or just not outputting at startup.
Now my PC just won't post properly.
I have got widows installed on a 256GB Vertex 4 with a TB HDD as internal storage.

Specs :
3570K
Sapphire HD7950
Asrock Extreme4 Z77
16 GB Vengeance 1866MHz
Corsair TX650 V2
265 GB vertex 4
Seagate 1TB

Now I have tried reseating everything and with minimal hardware installed.
Oddly enough I tried to reinstall or repair windows, but it does not find the damn installation on the SSD. So I tried installing on the HDD just for troubleshooting, but then it just wants to install SATA drivers. Its almost as if the SATA is not working properly.(That would explain the not booting issue)

I am not too worried about the GPU issue right now, just want the PC usable.

Questions?

Any ideas?
 


Will give it a try.
