[SOLVED] Vertical coloured lines on bootup

[darkwolf2411]

Vertical coloured lines when I start the computer. This happened after I did an AMD driver update. I've checked the cable if it's plugged in correctly with no change. sometimes its blank after a restart and most of the time its rainbow lines.

Which system ? Is that happening during post or after OS is up ?

Before. It's the first thing that happens. Even before bios. It's a brand new screen.

In that case driver update is not the reason, driver is in OS and OS is not working at that stage.
