Hi guys I have a problem and I cant seem to solve it :eek:.
Let me start with my system specs:
Mobo: Asrock z68 Pro3 Gen3
RAM: G.Skill Ripjaws 8GB 1600MHz (Yes I have tried both sticks and resitting ram and checked different slots)
GPU: HiS 7790 (Thats the GPU WHEN MY PC DOES NOT BOOT UP has been checked in different pc and it works) however it boots up on my ATI 3450
Processor: Intel i5 2500K stock speeds never overclocked.
PSU: Thermaltake M550W brand new psu (Checked and working)
OS: Windows 8.1 64bit.
I guess the other things dont matter.

I cant seem to go through boot my screen just says no signal when i plug in my 7790 but when I plug the 3450 it fires up with no problem...

Please help I'm really clueless..

ok please update your bios to the latest sometimes crazy things happen, and borrow a 650w psu for test puposes sometimes working a psu cause problems under heavy load. Also if you have a second pci-x socket try it and check if the gpu is plugged correctly in the socket(use a flashlight to inspect).

edit : first clear cmos
