Hello. This is my first Gigabyte purchase and I was really looking forward to it due to the ease of making it a Hackintosh. However, I have run in to some fairly significant problems along the way. After several extensive google searches I stumbled across a few people with similar problems (won't boot, keeps going in a loop until I hold the power button down) and their problem was fixed by returning the mother board and buying a different brand. Needless to say, that was disheartening to read and it is the last thing I want to do.
My problems began the first time I installed Windows 7 Ultimate. Everything seemed to be going smoothly, the install was successful and it rebooted to the setup stage. I typed in my username and password and such and it goes to the desktop. After between 10-30 seconds it quickly pops up Logging Off... followed by Shutting Down... and then the computer proceeds to turn off. Upon powering it on again it displays the Gigabyte logo and an underscore appears in the top left hand corner. From here the fans whirl up a bit faster for .25 seconds and then it crashes and returns to the Gigabyte logo. This sequence repeats itself until I power it down with the power button on my case.
I have run memtest86 and my memory seems to be fine as it went through one pass with no issues. At this point I am suspecting that it is either my GPU or a problem with my motherboard. Any insight towards this would be greatly appreciated. Thanks for your time.
