I got all the hardware today and I skipped back home to put it all together. I'm running a i7 860 on a p55m ud2 motherboard with 4gb of 1600mhz RAM, a 650w psu and a Radeon 5850 gpu.
Once I got it all hooked up I flicked the on switch and it works great, fans are humming and pretty blue LED's are shining. I go into the BIOS to manually set the RAM voltage and frequency as the p55m ud2 does not support 1600mhz by default and then I pop in the Windows 7 cd and start installing.
That was 4 hours ago. The goddamn thing won't install. I get an error message when the installer attempts to extract the files it needs (0x80070017). I've been all over the internet and found something like a thousand different people with the same problem and about a hundred proposed solutions, about 89 of which have yet to work for me. One of the few things I feel I haven't tried (and am of course unable to try until tomorrow) is burning a new copy of the install cd at a lower speed.
I was supposed to be playing SC2 by now.
