Hey guys i have a problem with my screen turning black or stripes while playing games, watching streams , movies . Stripes means that the whole screen is covered with stripes from top to bottom. the strange thing is they have gradients and also everytime they are in different color. The only way to fix this is to restart the computer from the button... no key combination works and also it starts making a repetitive glitch sound . will apreciate if someone can help . just updated my monitor and hard disk and the problem is still here so they are not the problem . Is it hardware or software problem and a suggestion on how to fix it would be great .
