Asus gtx 680 causing BSOD but boots and runs fine with it disconnected

[ScottttRFC]

gtx680-dc20-2gd5 has been causing me to bluescreen, I was messing around with ASUS GPU TweakII and set it to gaming mode, and was playing pubg with my mates, when i blue screened. since then, with the gfx card connected, it wouldnt let me install my vga drivers, so i disconnect my gfx card and booted my pc back up. and sure enough it worked. My drivers installed. I am just about to connect it back up and see how it goes. if it still BSOD, what would be causing it? Not enough "voltage" getting to the card or something else.

so iv just conect it back up and my res is stuck @ 800x600 and cannot be changed. It wont install vga driver even tho they are installed. says "this computer doesnt not meet the minimum requirements for installing the software."

It also didn't work on the monitor intill i plugged it into my gfx card.

I had performed a clean installation of w7, hence trying to install the drivers.

Your motherboard does not recognize that GPU has been connected. That is caused by either damaged PCIe slot on motherboard or dead GPU. Your mobo has second slot, it works only at x4, not enough for regular use but should be enough for test. Install your GPU into second slot, if it won't output display then the card is dead. However if it works as second slot, your motherboard is faulty.
