[Chris1216]

I read a previous post a out here but not to long a go and I'm builtng or trying to build a computer it turns on and all and if have my main menu. The problem occurs when I boot my devices and I get stuck on " verifying dmi pool data"! I read before it's was best to q flash but I'm worried about doing that and I'm trying to see if I can avoid that! I checked my cooling system ad everything is secure an properly set up!

I'm using a
gigabyte x58a-ud3r
CMOS 9900
i7 930
6 Gigs of ddr3 ram
1 terabyte hard drive wd caviar

*and as a side note I'm installing win 7 on a USB!
