First thing i would do is strip computer to basics, as in 1 stick ram, default bios, if you have onboard video use it and dont use video card, any usb device do not use when starting, external or internal, if you use more than 1 monitor disconnect all but 1. I have ran into that problem just nbot on that board and it has always been hardware or driver related. Mainly hardware. I hope this helps report back what you did and if you would be so kind list all hardware you are using, CPU, ram, hard drive , operating system, monitors, and any sound cards or add on cards, video card and so on.
Plenty of people on here that might help narrow it down.
