get an xp disk or burn a live linux cd and boot from that. If it boots that eliminates some things. I had an issue with some dell optis that did this after an update to sp3, the fix was to go into bios and change sata operation from ata to achi.
And if your corporate tell them to give you a new pc or re-image at least. Don't waste time with that.
