Crisis moment CPU Upgrade Dimension 2400 - help !

Good evening. I hope you can help.

My trusty old Dimension 2400 has 2gb of RAM, a 256mb PCI graphics card and has worked faultlessley since the day I bought it. :emotion-2:

However, seeing a faster CPU for sale on E-bay couldn't resist:-:emotion-15: 3.06 / 512 / 533fsb 478 pin SL6PG.  The intel spec sheet shows almost identical Vdd between my 2.66ghz chip and this one, so assumed it would just drop in and work.

I was wrong... :emotion-6:

When fitted, I got a little bit ofo whirring (the video card fan ?) but the HDD failed to spin up.:emotion-3:

I replaced my old chip and the PC worked fine

I've scoured the interweb and it seems that all should work well, so I'm bound to assume that CPU is naff ?  Am I missing something ?  Is the A05 Bios installed on my dimension up to the job of supporting this chip ?  Do I need to move some jumpers ? Download some software ?

Many thanks - I know my PC is old, but any help would be gratefully recieved

    Diagnostic LEDs?  If removing the NVRAM back-up cell for a few minutes to perform a reset doesn't help, I would have to say that the CPU is either bad, or incompatible with the motherboard.

    The Pentium 4 3.06 GHz [SL6PG] processor should be compatible with 2400.

    Sounds like you have a bad unit.

    Thanks for the suggestions.

    As I understand, you are suggestion that the NV Ram cell is that flat battery thingy I can see on the MOBO ? 

     What is the function of this related to the operation of the CPU ?

     Is the removal / wait process  "normal proceedure" or just a suggestion backed up by experience ?

    FYI -  I added the CPU to a cold machine

    Diagnostic LEDs?

    The only LED I noticed was green - steady.  Is this correct ?

    There are four diagnostic LEDs on the back of the case.  Sometimes the sequence of green/yellow/off can give a clue as to what is wrong.

    The NVRAM back-up cell is a coin shaped battery at the lower front corner of the motherboard.  In addition to holding the BIOS settings, the NVRAM stores a configuration of the computer's devices.  I admit it is a long shot, but resetting the NVRAM will usually cause the computer to re-detect all the devices.  If the processor is good, it might get it to work.  I'm afraid I agree with shesagordie, though, the processor is most likely dead.
