Win Xp sp3 installation on dell laptop results in Boot loop Help!

Hello. I recently Installed windows sp sp3 on my dell laptop and after i restarted the computer i found that i am stuck in a boot loop! i cannot boot to anything not safe mode or last known good config. Everytime it boots to normal windows, it gets to the boot screen scrolls across once and then stops and shows a blue screen for about a second, not enough time for me to see, and then it reboots and repeats the process. I have been able to see the bsod because of disabling the auto restart and it showed this stop : c0000221 unknown hard error \systemroot\system32\ntdll.dll. When i boot into safe mode it gets to the agp440.sys or whatever it is then restarts.
Now im pretty sure this is a common problem with sp3 installs, but isnt that normally on amd machines where you have to disable intelppm. Im running a dell with a pentium 4 m processor so it cant be that.

Specs of Laptop:
Dell
Intel P4 m
256mb ram
30gb hdd
Win Xp pro sp2 (kinda sp3 lol)

Please help!
Thanks will

(Ps this is my work supplied laptop)
