I'm having an even worse problem. I cannot boot from any of the live distros. Machine specs are: Core i7 870, Asus P7P55D-E Pro, 2x2GB Corsair Dominator 2000Mhz, XFX Geforce GT240, 3x250GB WD HDD in RAID 0, 2x1.5TB in RAID 1.
The DVD or CD will start loading and then after scrolls of text it states that it couldn't handle something or other, then says rebooting in 30 seconds...
I will provide more information regarding what specific error message i get with each specific distro. I may even take photos...
