Try disabling cores 0 and 1 instead of 2 and 3, and boot the system.

Im not sure it matters but, once when I upgraded from a dual to a quad it installed the new drivers for the CPU automatically at 1st boot.

In my device manager, It had listed 4 CPUs as it should, but 2 were the old Core 2 duo, and 2 were the new Quad for whatever reason.

I fixed by simply un-installing all 4 of the CPU drivers, re-booting and letting it re-install them all.
it then showed all 4 as the new Quad.

Although a very minor issue, there were no other issues or need to re-install the OS however.

So, NO.
I do not think a re-installation of the OS would be required for a CPU upgrade.

there is no option to disable core 0. but i have tried to disable/enable other core. same idea would lunch with 2 cores but not with four.
device manager can recognise cpu correctly but it shows only processors as i can only boot system with any 2 cores.

No, there is definitely no point to reinstalling windows. I suspect a hardware component.

I believe so, and would start with that. How old is your mainboard?

I'd look at what Whishmater suggested.

I think pointing the finger at the CPU being faulty is a little premature at this stage.
