I have since removed and reseated all components, still no change. I am unaware of how to have windows load in safe mode without any sort of prompting and... hardware specs, AMD Athlon 64x2 4200+, Asus m2n32 sli-deluxe motherboard, PNY Gforce 8500GT video carde, 3GB Corsair memory, 250GB Seagate SATA HD, OEM DVDR/RW. OS is Windows XP and it is a retail copy, CD's and all, though I am unable to locate the actual CD at this very moment.
