Hey there guys. I was hoping one of you would have an answer, since I've run out of ideas. I recently bought a used gtx 670 over ebay, and when it arrived I was having some issues. When I installed it in the intended system (asrock h170m pro4, 8gb ddr4, 500w evga bronze, i3-6100), i got some nasty artifacting (blue lines and dots) and the driver woukldn't install. I then moved it to another computer (intel h57 motherboard, 6 gb ddr3, same psu, i7-860) The artifacting went away and the driver installed without a hitch. However, with the driver (multiple iterations from nvidia) installed, the computer would only start in safe mode. I have no idea what could be causing this issue, so I'd appreciate some help. Thanks.
