Im having problems with my computer whenever I turn it on. I ALWAYS get the BSOD!!!!.....XP doesnt load it just takes me to the BSOD...but its the same error each time.... stop: c0000221 unknown hard error systemroot\system32\ntdll.dll But when i restart my computer it takes me to the boot options and i just go to start windows normally and my computer works fine after that... Anyone have any ideas what might be wrong?? I have reformatted and reinstalled XP numerous times and still get the BSOD!...could be a hardware problem??....if anyone knows what the BSOD could mean..help me out...thanks!!!
