Can integrated video card cause trouble updates?

I have a HP 533w computer installed with Intel Celeron which runs on 2.0 GHz. Contrary to the documentation, updating the processor to Intel Pentium 4 that runs on 2.4 GHz didn’t work. The monitor was blank and no single message was displayed at any time. However, the Intel Pentium 4 that runs on 2.0 GHz worked perfectly. I am wondering if this problem might be caused by the integrated video card that is currently being used. Anyone out there with an idea how to solve this please feel free to inform me.
