Why wont my IBM R40 Boot?

So the motherboard it came with was dead. I replaced it and the CPU with a brand new Pentium M CPU. I hit the power button, fan on cpu spins briefly then stops, hard drive spins, dvd/cd drive boots, and power on indicator turns on. Nothing shows up on screen and it just sits there with the hard drive running. Any idea?

Answer this question I have this problem too

Is this a good question?

Have you tried putting the original CPU back into the machine and attempting to boot with that? Likely the problem is from the new CPU. I would verify as well that the new Pentium M CPU is compatible with the R40. What is the specific version of the Pentium M that you purchased?
