Recently, I bought a Cyberpower PC from Amazon and everything was fine. However, while I play a game, either during the loading screen or as I am exiting, a diagnal pixelated pattern shows up for a few seconds and then my monitor shows up as no input(refer to images). During this, my computer still shows signs of being on, and I can't do anything to get a reaction from my computer. After my screen blacks out, my computer either is rebooted by itself or stays on without a display. I have listed all of the specs for this PC below and the only modification I've made is that I added an extra SSD.
-AMD Radeon rx580 4gb Armor OC
-Windows 10 64-bit
-AMD Adrenaline 17.12.2
-Monitor: ASUS PB279Q LCD 4K UHD 60Hz
-MSI B350M BAZOOKA AMD 350
-AMD Ryzen 7 1700 3.0GHz
-600W (I'm mostly sure, it doesn't specify)
-16GB DDR4 RAM
I would take advantage of your warranty/lifetime support. Simply put, NO COMPUTER should do that.
