Desperate HELP. Motherboard is acting really weird with Graphics card

Okay so I will try to make this simple as possible. I had already my Gaming Rig done about a year ago.(Check Specs at the bottom). My rig was perfect and no problems at all (until now ) My cousin doesn't know much about computers but asked my opinion on which parts to buy so I could build it for him. I build his PC (which motherboard came faulty so everything went in vain). I decided to take out my PC to do some dust cleaning and just check everything. Soon after i clean everything and try to boot my PC Windows froze.


PROBLEM : My Windows 8 froze, tried booting several times. Tried the refresh, trouble shoot, and pretty much everything i could think of.

So i Uninstalled the GTX 660 and connected the VGA to motherboard and EVERYTHING booted up normally. Like if nothing happened! I re-install the GTX 660 and reconnect the VGA to the card and BAM problems again. Problem here is that TODAY arrived my GIGABYTE WindForce GTX 980. I installed normally (thinking that my EVGA GTX 660 was damaged) and BOOM same problem occurs. I'm thinking that it could be the Motherboard. But when i boot into Bios it never freezes.

Please if someone could give me some insight on my problem...

  1. Try uninstalling and re-installing the GPU drivers. Uninstall them with no GPU attached, and reinstall with the 980 installed.
  2. it could be your psu. have you tried plugging your gpu into another pci connector

    What I also did is Erased Windows 8 from the SSD. And did a CLEAN installation of Windows 8.1.

    This is how it went down(WITH GTX 660 connected and VGA connected to it.
    -Inserted Windows 8.1 disk into drive bay
    -Erased the SSD and did a Clean installation
    -Booted into WIndows normally
    -After a few a minutes it freezes.
    - Restart PC
    - Same black screen

    I think PSU is more than enough for the GTX 980
  5. Your psu might be bad. Have u tried it in another computer?
