My system was fine but for the past few months. Runs everything fine no issue. The GPU crashed the other day and it forced me to reinstall drivers. I've lost my 4k resolution. I'm running dual monitor set up 4k & 1440p. My 1440p is fine, resolution is normal but on my 4k, it default to 1080. Sometimes I see the option to select the 4k resolution but then when I select it, the screen will flicker, go black and then go back to 1080. I have the latest drivers.
