If your computer is bogging down and coughing up lots of error messages then the best thing that you can do is to run a registry cleaner.  These programs will help you narrow down the cause of your problems.  Many common computer problems are caused by registry errors, and lots of people don’t realize this.  They think that after a while they just have to get a new computer, but this is not the case.

If you’re looking for the best registry cleaner software then I highly recommend RegCure.  This program has given me great results and I use it to clean the registry on the very computer with which I’m writing this.  My laptop thanks me.  

I definitely also recommend investing in more RAM.  If you want to upgrade your computer then this is definitely the way to go.
