i upgraded my old compaq from a 300mhz celly to a 400mhz celly processor and now it wont boot. its a compaq 04C4H motherboard with intel i440LX chipset. the fans spin and hard drive makes a few noises but nothing appears on the moniter. i tried the old 300mhz and it works. why wont the 400mhz processor work?
