Please HELP me (windows intallatin error)

[far]

I have this Computer for 2 years (pentium 4), i have installed xp many many times on this system.

But this time I can not install xp.
Error
Bad_pool_caller
stop: 0x000000c2 (0x0000007, 0x00000cd4, 0x11111111, 0x8187bc48)

I have not installed any new hardware. I got same xp cd.

I thought i may have problem with my hardware so i bought Linux and installed working very fine.

But i need to go back on xp.I am stuck for a month now.

Please help. thanks
