Hi James,
I guess you will have to be more specific.
Start by listing what hardware you have, motherboard, cpu, mem etc.
Linux is in general more fussy about memory. Needs to be good, and all modules must be the same, and you must have plenty of it. I think less then 64meg won't play, and for serious work start thinking 256meg upwards.
For the rest, Linux runs on the most obsolete hardware you can imagine, (but not necessarily SME) so I would guess you do have hardware issues..
But like I say, simply saying it don't work without details, does not get you anywhere...
lets hear more!
