Question My PC has boot problem

[burabotti]

I have asrock x79 extreme4 motherboard and i7-3820 cpu. Everytime i try to boot up my computer it wont. And it gets stuck in those error codes (different every time) that you can see on the motherboard? This has been happening for a month now. I sometime get it to boot when i put in a DVI connector.

Try testing different graphics card and/or different power supply.
