hello, I recently bought a gaming computer that supports 4k resolution. Everything went fine for the first few weeks (4k video games and videos look amazing), however recently I have been having some problems. When i start up the computer, it will often completely freeze up once i start a game, or even when i attempt to open up google chrome. Normally, leaving the computer on for 15 mins before starting anything would fix the problem and prevent the freezing, but it is still an annoyance for me.
Yesterday, when I attempted to start up the computer after it had froze on me, the display was only showing 640X800, or whatever the lowest resolution is. I went to display settings and it would not allow me to adjust the resolution. I managed to fix this by going to the device manager and updating one of the video drivers.
Now (after a few startup freezes once again), the computer will not go any higher than 2560X1440, and not the 3860X2860, or whatever the native 4k resolution is. I launched a few 4k videos I had downloaded on my pc and they seemed to work with no issue. however, when I attempt to start a game, the game will only allow 2560x1440.
the task manager is telling me all the video drivers are up to date, and I tried a system restore to no avail.
for reference, my video card is: PowerColor Devil 13 Dual Core Radeon R9 390 DirectX 12 AXR9 390 II 16GBD5 16GB (8GB x 2) 1024 (512 x 2)-Bit GDDR5 PCI Express 3.0 CrossFireX Support ATX Video Card (no idea what any of that means)
also, for whatever reason, I haven't been able to access the radeon settings menu, where I could access the crossfire settings that would allow me to switch between using one, or two, of the video cards simultaneously
My computer savvy friend who built it for me told me to monitor the temperatures of the parts. He said never to let any of the temps reach over 80 degrees. Ive been checking and the video card has not reached a temperature of over 70 degrees so I don't believe temperature damage is the cause (at least I hope not, its a 700 dollar card)
any advice would be greatly appreciated. At least in the meantime I can still enjoy games in 2k hehe
