i have hp pavilion tx 2000 that has AMD processor and i wish to change to intel i5 is it possible?
Unfortunately No. AMD is a completely different socket & chipset than Intel and would require you to change the motherboard to support Intel Core i5 CPUs. This would be easy on a desktop but because this is a laptop you'd be better off buying a new one. Changing a laptop motherboard is extremely expensive (if even possible on this model)
