i was switching a Ti4200 video card from an old computer into a new comp that i was building. The new computer wouldnt boot..at the start it would just beep 4 times and it wouldnt post. So i just assumed it was the motherboard, so i RMA'd that and got a new one, i set it all up again and it did the same thing....beeped 4 times. So i tried different memory....same thing, beeped 4 times, comp. wouldnt post. so finally, i tried an old viper video card and voila...it boots right up. I thought this was weird since it had worked absolutely fine before. So then i threw the Ti4200 back into the original machine i had taken it from...and the same story as before, beeps 4 times and the comp. won't post. what gives? i was very very careful about static, making sure i was grounded at all times. But now this thing doesnt seem to work at all....why might this be?? and what could i do to get it back on its feet?

Not sure just how much help this will be but here it is anyway.

Not real familiar with the Video card in question but could this be an issue of incompatible AGP speeds. I assume the new board is 8x. Usually AGP is backward compatible. In this case that would be 4x. That may not be the case though, you need to look at the board specs. Anyway, is the old card at least 4x? All this assumes the old card is good to begin with.

It sounds like your card was not compatible with the new system. AGP cards of different levels use different voltages. The new system might have fried the card.
