Hi.
Before I've bought a new GPU I was using the Quadro 600 and I've had an overclock on the Xeon processor from 2.66GHz to 3.2GHz and it was running pretty much good.
About a week ago I bought a new GT 1030 OC 2GB from Gigabyte (https://www.gigabyte.com/Graphics-Card/GV-N1030OC-2GI#kf) and after replacing it, the computer posted, but there was no display output. I've resetted the CMOS and I've had an output, but every time I try to overclock the CPU, there is no output, even when I just do from 2.66GHz to 2.7GHz. This also happens even when I put my old Core 2 Duo E7300 and trying to overclock it. When plugging the cable to VGA I have an output.
So the main problem: When the overclock is enabled, I have no display output, but pc posts, when disabled or plugged in to integrated gpu, I have an output.
Any help?
