Bad GPU or bad Motherboard PCI e slot

[LoneSombrero]

Recently i was playing a game and mid game my computer crashed with horizontal lines streaking across the screen, nothing i did made the computer respond so i hard rebooted my computer to see if it would solve it but instead, my computer would boot and stick to the bios screen then proceed to a black screen with nothing on it, not even a cursor, after 10-20 minutes the windows recovery screen shows up saying there was an issue booting. I tried every option that the recovery menu offers from command prompt to a complete system reset. It wasn't until i removed the video card that i realized that this was the issue. Even now if i attempt to install the video card i get the same black screen followed by the windows recovery menu. I'm wondering if this is a common symptom of video card failure or is my motherboard PCIe slot failing. My system consists of an i3-6100, 8GB of DDR4 Ram, and an AMD R9 270x. The CPU, Mobo, and RAM are 6 months old while the video card is 2 years old. The Power supply is a Be Quiet 550w but i checked it with a PSU tester and all the results were normal.

I see add-in boards go bad more often than the slots they are plugged into. Most likely your graphics card is dying.

Using the on-CPU graphics, you should be able to boot the machine fine if the graphics card or slot is the issue. The only other test would be the graphics card in another system or a known good card in your system. That will tell you if it's your slot or your card.

Another possibility would be the power supply, but with such a low end graphics card, I highly doubt the PSU is under-powering anything.
