Here is the dealy-o:
The computer is a Viewsonic Media Center PC. I unistalled a WinTv tuner card, to replace it with a soundcard. Installed software for the driver for the soundcard; it randomly powered off (not unusuall for this computer). On bootup: no video output. Monitor text reads: No Signal. This problem excludes disc problems: the hard-drive functions propperly. Motherboard: extention cables to front port (for easy access [on additional card]). Only one PCI slot, the tuner card was installed there. So in short: WinTV tuner card was replaced with a sound card (bypassing the motherboard in which interlinked functions with the card).
Already attempted replacing video card.
