I have two hard drives quantum of 10gb and maxtor of 40gb, and check both one by one

first of 40 gb:
c:
d: unformated disk
e: unformated disk
f: unformated disk
g: unformated disk
I have not checked my drives in other computer

Second hard drive:
c:
d:
e:

yes bios recognises the drives. I have checked all cables. If there is hard drive problem then both should not have the same problem, I think.
When I tried to install winxp then error message was "KERNEL_STACK_INPAGE_ERROR".
