Check the BIOS settings for "HDD Delay". If the HDD is a little slow at=20 becoming up to speed and ready, there might be an unknown state, and the=20 computer just sets there. I have 2 Intel DP965-LT motherboards. One has=20 2 Maxtor 320G SATA HDD's and boots with no delay. The other has 2=20 Western Digital 320G HDD's and requires a 5 second delay. Will have to=20 try a shorted delay, but for the moment OK. Sometimes get no Boot Drive=20 found, but usually just hangs. Don't disagree on possible PS. Also try=20 removing everything including keyboard and mouse. Power it up, should=20 get 2 beeps for no keyboard. Then add items back in. If more than 1=20 strip of memory, try one and swapping.
