hi all, I've just built my new system, and now i can't get windows to install. my specs: amd 4000 cpu san deigo core water cooled dfi nf4 slr-dr m/b bios 6.23-3 1 gig corsair xms3200 cl2 ram 2 10gig wd raptor sata drives xfx 7800 gtx nothing is overclocked, i have set the nvidia raid up under the bios and raid setup screens but windows locks up when installing with an error code of 0x00000007b..... it says to unplug any new hard drives or controlers. i've tried the slip stream cd with the latest drivers included but it hasn't helped the problem. anyone got any ideas?
