actually BA, there are 3 but they've been sent in over a couple of days
i think that for the lay person the thoughts of replacing the processor and mobo (mother board) are absolutely frightening, and i can understand that. i wouldn't want to do the job myself, either. with that said, there's a very good chance there's a capable technician in your area who could make the swap for you.
consider the prices of upgrading to a new processor and motherboard right now (all prices are from radio shack, so both the components and the PCs could be had for cheaper):
$208.49 - Athlon64 3800+ Dual-Core Low-Voltage 2GHz Skt AM2 Processor
$160.00 - MSIŽ NVIDIAŽ nForce 570SLI ATX Socket AM2 Motherboard
$100.00 - estimated labor
-----------
$468.49
compare this to a comparable prebuilt computer now available with the same processor and same or similar motherboard:
$775.00 HP A1700N Pavilion Windows Vista Premium Desktop PC
$599.99 HP Pavilion Slimline s7700n Windows Vista Home Premium PC
a savings of $130-$300 PLUS you don't have to go through the pain of moving all of your files from your old hard drive to the new one...
