To speed up a computer it needs to have a faster CPU and enough good quality RAM memory, second, a fast enough hard drive with enough storage space on it.
But to speed up the Internet you need a faster Internet connection.
----------------
Both: Your Pc's speed and your Internet connection speed are probably more than good enough as they are right now.
Maybe the only 2 things that you might need to check are:
#1: To see if your hard drive still has enough free space on it.
If it doesn't, uninstall some programs that you don't really need, in order to make more free space on your hard drive.
#2: Check to see if your computer has enough RAM memory on it.
It it doesn't have enough RAM on it, check to see if it will take more RAM, if it can take more RAM, buy more RAM for it.
--------------
Before you spend any money on your computer have somebody check your Pc first to see if you really need to spend money on it, also do that before you uninstall too many programs from your computer.
---------------
Too bad that not everybody knows enough about computers, to know might save people time and money.
---------------
Don't buy a new computer unless you really need to.
Your new computer might soon become as bad as the old computer if you don't know what you are doing.
Best find a local person who knows about computers and have him or her check your computer.
