No picture after Ez Tuning Wizard OC

[Scintillo]

I tried Ez Tuning Wizard and after I ran it I got no picture. I could login to Windows blind and everything else was working fine. (Windows login sound played and so on.) Only way I could get the picture back was resetting the CMOS using a jumper. Any ideas why this would be happening? Should I just resort to manual overclocking?

If you can log in blind, it sounds like an overclock is causing your GPU to not get enough power. A bad CPU overclock would fail to boot or bluescreen. What PSU do you have? A low quality or low wattage PSU could be the cause.

I'm not sure about the quality of that power supply, but 500w seems like enough power. Maybe try overclocking manually instead and see if you can get it to work then. Automatic overclocking tends to not provide optimal results anyway.

If this is indeed a GPU overclock issue, then I would recommned using MSI Afterburner to manual increase the performance
