If you've made all those hardware changes, then you will probably need to reset the CMOS memory, which would reset all settings to default values, before the system will boot.

Power down, disconnect the power cord, open it up and remove the CMOS battery. Wait at least a few minutes before replacing it and seeing if the system will boot.

If you've replaced the cpu with one which is unsupported by the system BIOS, you will need to put the older cpu back in, and perhaps even update the BIOS to allow the system to recognise the new cpu

hello u mean that first my mother board is ok. i only remove the cell , and replace it with a new one.. plz

No, I mean pull the battery out, wait a bit, put the battery back in.

That should clear the CMOS settings and set them back to factory default values. It gives you a 'starting point' for trying to get things working.

While you're in there, check that all cables and connectors are firmly in place, and that all cards etc are firmly in their slots.

A quick question:

Did you turn it off and disconnect the power cord from it before you started changing all those parts? If you didn't, you've possibly blown it up! there's still power inside even when you've 'Shut Down' if the power cord is still plugged in.

Beyond that, we need some technical details please. Names, numbers.........
