Main monitor flickering after connecting a second monitor.

[daxtera nikolov]

I connected a second monitor to my pc and suddenly my main monitor started flickering. I got a little spooked so i disconnected the second one, but the flickering was still there. I then used ,,Display Driver Uninstaller'' and it was flickering even without drivers installed. It is really annoying. Please help.

I put my pc cable and my monitor cable on the same power strip.
