Okay, I fought this issue for a few weeks now, and I'm running out of ideas. I woke up one morning to find my GUI all corrupted as shown on screenshots. I restart and all is well for several days. After that time period the problem repeats. I wanted to use a screen capturing software to capture this, but PC is unusable in that state. The computer is virus free, I updated graphic drivers, ran chkdsk and system file check. Anyone knows what might be causing this?
