so recently got a computer because the owner said it wouldnt turn on.(Free !) it had a 250 W PSU in it so i started there bought a new one that has a 350 w supply but the computer still will not start. it is an Emachine T4510 and i dont have much faith in it but it was free and i want to know if i will have to invest in a new board to get this to work and weather or not it will be worth my time to fix it up. please helps.
