It is extremely frustrating to have a slow computer. This is why I went around asking how to speed up my pc. And, here are the things I have found that have worked for me.
Use a defragmenter
This software utility, that comes with Windows, will scan your hard drive and fill in th empty spots with files. What happens is your computer will start saving files in fragments, by filling the first openings on your hard drive. This means that when you start the file, you need to wait on the computer to put the program back together. A defragmenter will fix this.
Max out your computer memory
Computer memory is relatively cheap these days. So, there is no excuse as to why you do not have the maximum amount of memory installed that your computer allows.
I Run a registry repair software weekly
The registry is an area in the computer, deep into the computer, that contains a set of instructions, or directions, on how the software and hardware in the computer should run. If anything in here gets messed up, the software ends up looking for the wrong stuff, or looking for the right stuff in different locations. This can definitely slow up a computer.
The registry repair software will run a scan of your computer and let you know how many errors you have. Then, with the click of one button, you can fix all of them. Now, your computer will run fast again.
These are a few things I have done when I was asking how to speed up my pc. These things can also work for you.
