Speeding my computer up with a RAM memory upgrade

I have always been a multi-tasker and my computer suffers for it. Whenever I work on my charts, emails, tables, and video editing tools, I would also be downloading porn and watching YouTube videos. I open several browsers and programs all at the same time and switch from one browser to another every now and then. There was one time I experienced being in a middle of a very important report when my computer suddenly shut down buy itself. After that incident I summoned help from my friends who are into computers. They told me that I should add RAM memory upgrades to both my Apple memory and Dell memory. I went online at MemroyUpgrade.pro to get some information on how to go about the upgrade. The website has been very helpful in providing me information on the things I will need to go about speeding my computer. I was able to order online and have everything I need delivered right at my house. The video demonstrations online helped me do the upgrade myself.
