Hi everyone, this is my first question in here. I recently updated my graphics driver of my laptop Dell inspiron 7520. I reinstalled the corresponding intel driver first and then the latest amd driver 15.7. When my system boots up my desktop appears with multi coloured horizontal lines which disappear after two minutes.
Intel i7-3612qm @ 2.1GHz
Ram : 8GB
Video card: AMD Radeon 7730m 2GB
Hard disk: 1TB
