If it's a fresh copy, and installs fine I would believe it to be a number of things.
Have you tried MeMtest at all? Just to troubleshoot whether RAM is giving you grief.
Try using a different monitor? Perhaps something is wrong with the display, if it doesn't load correctly when booting?
Perhaps the Hard Drive is at fault? Since it loads correctly at start up, but then when loading the OS it fails?
And the motherboard, though I think if you could install Windows, it should work.
Interesting case. I shall watch and listen to the experts.
