Last night I removed my motherboard and installed a new cpu cooler (CoolerMaster Hyper 212 Plus). I then reinstalled the motherboard and all connections and when I try to boot I get "Reboot and select proper boot device or insert media in selected boot device and press a key". I'm running Windows 7 64 bit on an Asus P6T Deluze MB, Intel core I7 920 processor 6GB of ram and 3 SATA drives. I didn't make any other changes other than installing the new cpu cooler. I tried changing the boot order to boot from the cd drive first. I put the Windows 7 DVD in the drive and it won't even try to boot from the cd/dvd. It immediatley goes to the message above. I also tried unplugging all the SATA drives except for the boot drive and get the same thing. I need to be up an running asap this weekend as I have to vpn into my office pc to do some work. Any help would be greatly appreciated. Thanks!
