Make and model of the PC?
What do you mean by "don't come on at all?" When you power it up, do you hear any beeps?
Try this. Reinstall the vid card, one stick of memory, and hook up your keyboard and monitor. Leave all drives disconnected, any other cards (e.g. modem, nic, sound) removed from their slots. In this 'basic' configuration, power up the machine and see if you get anything on the screen. If you do, write down exactly what it says, and let us know. If you hear any beeps note those as well. Some motherboards use different beep patterns to indicate problems with various components.
