Ok, heres the lowdown on the problem...
I just installed a new CPU in a desktop machine, now ive repeated this process a few times, interchanged the CPU's between machines several times, mainly because after going from the old AMD CPU to the new one i lost my Mouse... no matter what i did whether it be PS2 or USB it just died. So i poked around, couldnt see anything a miss, no setting no nothing, so i decided thats its probably just windows and i went ahead and changed the CPU's over again - so the new one was in.

This is where it gets weird, the computer boots up, and... nothing, the HDD's spin up but dont go further than POST. Ditto for the CD-ROM/DVD-ROM drive, no beep, no screen. Power is getting around ok and theres no flaming components anywhere...

What could be causing this - it did it a few times with the old CPU as well? could the motherboard be inoperable?

Clear the CMOS and if the problem persists, yes it is the motherboard that's got to go.

In changing the cpu over,soes the system recognize the cpu in the bios setup,the hardware detection could be the culprit,mouse may be causing the system to hang,update the drivers by booting the system into safe mode

Make sure that you have not bent any of the pins on the cpu

Firstly Flash the BIOS to the latest available AMD need this for some reason. Then depending on how you are instructed to do this the best thing is to clear the BIOS and reset it.

If that doesn't cause a cure the most likely culprit is the M'Board. Also does this model of M'Board support that AMD CPU? @While it may see it and have the same socket it might not be a supported CPU.

First, ensure that motherboard and installed BIOS support your new CPU.

Clear CMOS (jumper or remove battery for 5 minutes or so)

Update BIOS if necessary to support new CPU. That will have to be done with old CPU installed.

it would most likely the hardware is not seating properly. try to dissamble everything and reassemble back (carefully) and you should reset the BIOS before turn on your computer.

Check the main board manufacturer's site for supported CPUs. If you are installing a Sempron you may need to up date the BIOS. Verify from the main board's site.

And yes as already stated clear the CMOS.
