GPU no display detected

[gabrielkfr]

Bumped up my memory clock on my gpu with afterburner and ran test on kombuster, test finished but pc got laggy, closed kombuster and reboot normally, boot up with no display, gpu is on with fans turning, what could be the issue? It boots up into windows and I can hear the sound when you plug in usb, just the monitor says no signal, advice appreciated!

have u also tried other display out ports on ur gpu?

or try using other display cables to connect to your monitor..
