Upgrade my 2012 Dell XPS with Intel i7/8GB RAM 512 GB SSD to Win 10?

[mayur.basude]

All,


I had purchased a Dell XPS 15 laptop in 2012 with the following specifications:

Windows 7 Pro

Intel i7 2.2 GHz Processor

8 GB RAM

changed the Hard disk 512 GB Samsung EVO SSD 1 year ago


However, recently (last 1 month) the computer has been running very slow (and with very slow wifi/internet speeds, most times less than 1 mbps on a 16mbps connection) and the fan constantly running at full speed and Battery showing "Consider replacing your battery" message.

Please advise what should i do to make my machine run as fast as earlier?

- Will replacing battery with a new one help?

- Should i upgrade to Window 10 from my current Win 7 Pro to have better performance?

- Is overheating of machine internals (processor) making my machine slow? Do i need to clean the machine/fan inside for better cooling?


I am not looking at replacing my computer for at least another 2 years.


Thanks,

Mayur
