Hi, I am wondering what would be best to salvage in a pc and how much it would go for.
first you have to put what parts you have generally psu cpu and graphics card maybe even ram case motherboard...ram you can salvage everything
Look inside the computer for any loose wires or cables. If any of the cables or wires appear to be loose, tighten them. It is not unusual for even well-seated cables to come loose with time, especially if you have moved your computer around a great deal. After re-seating the cables, leave the case open and try to start your computer again.
