Help Upgrading System (New MB & CPU)

Hi,

I have a friend who just recently decided to upgrade his Alienware-made
computer with a faster cpu and motherboard. He went out and bought both and
installed everything correctly, however, chaos struck. When first started
the system would not recognize the cpu at the right speed and after attempts
to make it closer or the actual cpu speed the computer became unstable and
eventually wouldn't load at all. He sent it to a shop to be looked at and
they couldn't figure out what the problem was (a well lost 60 dollars ),
and now the computer won't load up past the bios screen. If anyone has any
insight or knows of any problem or can help us get this machine working I'd
appreciate it greatly, as my friend is at the point of just going out and
spending a few grand just cause this rather good machine he has now isn't
cooperating...Thanks in advance...
