The PC specs say P4 or Celeron. I suspect a dual core simply will not work with the motherboard....... A google on the SiS 661FX chipset suggests that this is almost definitely the case.

Any Pentium 4 CPU with 800mhz FSB is the max for that board, i'm assuming your brother has a Celeron processor.

But as its older technology i would be inclined to get a new motherboard.

Its an older PC and probably, isn't worth spending too much money on it, ages ago i had a knackard bell if he can afford it this is a good little pc, if your after it for gaming will need better psu and graphics card, dad bought one and I set it up, speedy enough rig.

I have a pentium 4 640 with HT that should work in that mobo if you dont want to spend a lot of £££ or buy a new PC.
