I have an old compaq 5002us desktop that has an 800mhz duron cpu, I bought a 1.3 processor. I took out the old one and put in the 1.3 and the computer runs but nothing ever comes up on the screen. I put the old one back in and it works fine. they look identical and all the pins are the same, why will it not work?
