I am having intel pentium in my laptop but it seems to slow so i want to upgrade it... i only want to know is it possible to change its processor.. or i should buy new one.. which will be good
Perhaps you can upgrade your processor, however I cannot be certain without more details.
Please if possible, download and run CPU-Z, take screen shots of the CPU and Mainboard tab, then reply here with those shots. Also please provide your laptop manufacturer and model if you are aware of them.
Once I have those information, I'll look into it for you further and declare if you can upgrade your processor, and what you can upgrade to.
