HD Install :: cant boot from live cd to desktop

I have the same disc that I can boot just fine on my dell laptop, but on my desktop it dies when trying to boot the kernel.
If i just let it boot itself, I get the little penguin & it stops there.
If I try dsl vga=normal base toram it says uncompressing linux... Ok, booting the kernel. and that is where it stops...
same disk will boot just fine on my dell latitude c600

I dont know if hardware is an issue here but here is what I have on the desktop

2.8ghz p4
1.5gb ram (cant remember the brand I bought)
soyo dragon 2 moboard
nvidia fx5700 agp
1 ide drive/ 1 sata drive

no takers?
perhaps I should give you more info? Im willing to answer any questions on this, I just dont know where to start with it though...

try to boot like this:
dsl noapic nomce noscsi nopcmcia
