Hi All,

Bought a computer a few weeks ago, running two Radeon HD 4870's in crossfire on a DFI X58 T3EH8, i7 920 with 12gb ram. Formatted drives, reinstalled windows, all was working well.

Then, a few days ago on boot, computer reached the "starting windows" screen, the windows logo froze and it didnt get any further. Tried a few things, but eventually gave up and formatted my drive, reset bios etc etc. Went to reinstall windows. Setup worked, went through the first restart, reached the "starting windows" screen, and hung again.

After a couple of days I clicked and took out the second GPU, but now when I reinstall the GPU, I get the same hang on boot.

Anyone got any suggestions about where I should be heading? Seems like i've made a mistake somewhere in the bios, since I had the exact same hardware running with the exact same version OS a few weeks ago...

Cheers for your help!
