did u ever unplug everything? as in EVERYTHING but the vid card (reseat it, though), primary HDD, memory monitor and CPU. Remove/unplug the cdrom, floppy, keyboard, mouse, any printers or scanners or cameras/webcams, basically EVERYTHING. It will give you a keyboard error of some sort, but at least you'll have a screen if it comes up.
If you argue with an idiot he will drag you down to his level and beat you with experience.
