So, I have bought the AMD Radeon R7 360, and I've been having a huge headache to make it work. Whenever I plug it into the screen without the driver, it displays color-related graphical glitches, while not having such issues with the onboard one. And whenever I install the driver, no matter what version, with crimson or not, or having done a whole procedure of using Display Driver Uninstaller, it crashes just before Windows can actually load. So, have I got a faulty GPU? If not, what can I do to make it work?
Processor: AMD FX 6300 Six core
Motherboard: Gigabyte GA-78LMT-S2
PSU: Corsair CX500
RAM: Kingston 8GB DDR-3
OS: Windows 10 Pro
It sounds like a faulty GPU. You could try using a different display cable or seating it in a different PCI-E slot.
