Upgrade my Laptop's Processor, Hard Drive, and Ram

[aycc]

I have an HP Pavilion Entertainment PC with an Intel Core 2 Duo Processor T 5550 1.83GHz. Also would like to add more RAM.
Can I upgrade all of them or some of them to make my computer faster.
Thanks

Buy a new laptop, the RAM that would work with it is old and slow anyway, and upgrading the CPU to anything modern and better would require a new motherboard.
