Recently I upgraded to Service Pack 3, and now it seems that something has gone terribly wrong with the update.

After logging in, my computer will blue screen after about 5 minutes and then go into a reboot loop (I don't have the exact error message handy).

I have a Sager NP2092 notebook, running an Intel chipset.

I'd rather avoid having to reformat my XP, especially with my copy of Windows 7 arriving right around the corner.

After doing some Googling, I came across this article: Does your AMD-based computer boot after installing XP SP3?

However, it deals with the AMD chips, and specifically states not to use its fix on Intel based systems.

EDIT After killing the reboot, this is the error that pops up:

STOP: 0x000000F4 (0x00000003, 0x8A187118, 0x8A18728C, 0x80604438)

EDIT2 I have run Memtest86, and it reported 0 errors.
