hello i am using dell studio 1558
which is having i5 450m 1st gen.with AMD mobility Radeon HD 5000 series . i want to upgrade my processor..
please let me know what are possible upgrades available..
You must to contact DELL and ask them which processors are compatible with THEIR BIOS.
An upgrade processor must be socket, BIOS, and chipset compatible.
Personally, upgrading a 1st gen processor will not do you much good in today's world. It would be far better for you to upgrade to a new(er) system, especially if Windows 10 is your goal.
