is the vid card intergrated? More than likley, you get power but no post or a dbl beep. Sounds like you need to crack the case and reseat the vid card. Just watch for ESD. Its doubtful the program caused the problem, just bad timing is all. Anyhow, when you turn on the power if you get ONLY the monitor is working fine, please check connection or some sort, and get no post screen (showing system type, speed, memory, drives, etc kind of looks like dos), then the culprit is the vid card. Driver has nothing to do with it, its physical. Just open the case, find the vid card, take it out check the connectors and the slot for any foreign objects, blow in it if need be, and reseat. Make sure its firmly in place. Again watch ESD and make sure the system is unplugged. Then when the vid card is reseated, hook the monitor up and restart. If its intergrated, or if multiple reseats (yes, you do sometimes have to do that, so dont screw the case together yet, you may need to do it again), if none of this works or its built into the mother board then unfortunately it sounds like A: If intergrated bad chipset. You can either replace the chipset (good luck! Get a chip extractor) or, and this is more likley the case, replace the mother board. B: If it has a stand alone vid card, you'll need to get a new one. Make sure you get the right kind, IE if you have no AGP slot, make sure you get a PCI card, and assure its NOT just an accelerator.
If you argue with an idiot he will drag you down to his level and beat you with experience.
