Depending on Pavilion model and age, either course of action might make sense.
Which model do you have? Processor speed?

You might also be able to mount a 3rd party motherboard in the chassis, but
unless it is a judicious choice, there will be problems with getting the
operating system to work correctly with the motherboard. If the operating
system is XP, you will undoubtedly have to re-activate on the Micro$oft web
site.

Thanks, It is a HPT550A,,, it has a pentium 4 2.8 Ghz 25 6 mb 266mhz sdram
7200rpm ultra DMA hard drive with windows XP. I would like to get it up and
running so I do not loose every thing on the Hard drive, (I am not the best
person when it comes to backing things up) however often jobs like this can
snowball and it might also turn out that the hard drive has alos failed.
Thanks for your help.

David, I read your post about the power supply failing on the
Pavilion. (Followed by the on/off, display, ect.). I don't know for
sure what the problem is. However, I would encourage you to visit the
following HP discussion thread. It might assist you to keep all
functions running properly, if the power jack and supply work are
maintained as appropriate. (I posted there regarding my problems with
the Pavilion power jack.) Good luck.

HP Pavilion Laptop Owners with Bad Power Jacks....

From what I was able to decipher on the usually obscure HP web site, the
computer is a micro tower, not a notebook... Ben Myers
