I have been trying to upgrade my CPU from a Pentium4 1.7GHz to a Pentium4 2.4 MHz. When new chip is installed, computer will not boot. Power comes on, fans run but screen is black. I put old chip back and all works fine. Thought it might be power so I bought new Power supply 350w(almost double the old 180w). Still won't start. Thorough research indicates mobo supports this CPU. Upgraded bios. According to data, the new CPU runs at 400/533MHz system bus. In the bios, system bus is set at 400.
Should I change this to 533? If I do, will the system I am running(old CPU)
croak? Should I change a jumper on the motherboard? Clear cmos?
Finally, do I know what the heck I am talking about???[/b]
