I have a freshly built computer. All new internal parts (HD, DVD drive, MoBo, video card, processor, PSU, RAM and case). Here is a list of all the parts that are in it: Newegg.com - Once You Know, You Newegg
I also have a fresh copy of Windows 7 OEM.
All parts are plugged in properly, and bios set up correctly (as far as I can tell). The only bios that aren't at default that I can remember off the top of my head was that I disabled the floppy section (don't have one), I raised the clock speed of my CPU to 2.8 (up from 2.66), and I enabled my CPU to raise 9-11% capacity under heavy loads.
Everything saved properly, and my CPU runs at roughly 35 degrees C. Not nearly as cool as my old rig but not that bad. The default settings had it running half a degree cooler.
Opened up the 7 case, popped it in, booted from CD-ROM, and a black screen comes up and says "Windows is loading files..." A bar fills up really fast, and after it finishes it resets and starts filling up again, much slower. Once this bar fills up however, the computer hangs and sits there. I've let it sit for over 10 minutes with no change. The only notable thing that happens is about 30 seconds after it fills the bar the DVD drive has some activity, and then it goes silent for the rest of the time.
Any ideas? Again, this is a completely fresh system. All the hardware pieces are brand new and I was able to go through and do bios without issue.
