I have tried to get help from here but then everyone stopped replying and I really need help with this issue as it's an annoyance. I got myself a computer from CyberPowerpc but when I play games now it starts to flicker the screen till it just crashes and then a loud buzzing sound starts being heard and I cannot get out of the game so have to force shut down the computer but when I do so the graphics card stops working properly where the screen is all torn apart and can barely see the screen till I disconnect and reconnect it back to the computer but at times it doesn't work till I do the same thing over and over again like 20 times. I have tried every solution I could find which was trying to lower the voltage, put the power limit up but it keeps on happening. I cannot play a simple game now as It will just crash. Also one thing to add is the temperature is up pretty high at times even when i am not gaming as it stays up at 49c. I closed every application down as well to see if it would work and nothing would happen but it gets worse when i get to a game as it is more than 53c at times. Help!
