Okay so here's the problem I'm having, my boot up is freezing right before it gets to the Windows XP boot logo, the same thing happens when I try booting into safe mode, last known configuration, etc.... The boot log freezes at the driver volSnap.sys everytime. I've tried booting from my windows xp cd and it wont load either, just freezes at the same point. I'm really stumped here guys so any help would be greatly appreciate. System was running fine before this happened! Here are my specs:

AMD Athlon XP Barton 2500+
Abit NF7-S Rev. 2
ASUS Radeon 9600XT
512MB OCZ Dual Channel PC3200 Ram
Seagate Barracuda 80gig GD
LG 52x cd rom
Windows XP Professional Edition

Please help!
