And thats when all the problems started.
FIRST i could barely start the pc. It randomly crashed and started a beep sound.
Then a few days later this problem dissapeard but new ones appeard. After i started my pc it crashed with a random color on screen. After this problem dissapeard All my games are now crashing a few minutes after startup. I tried: Unturned, CS:GO, GTA 5, Just cause 3. All resulting in a crash. Also, sometimes after the game crashes the whole pc crashes and the colored screen and beep return. I really dont know that my pc has. But i know its really messed up. I need help. Thanks in advance.
