Help me my computer sucks!?

I have a dell (yes i know shit already) but when i try to download games from a cd i.e the sims life stories it always says there is an error.  I have 2 computers.  the second one dosent have internet so it sucks to play games on there.  Please help i have tried everything with this computer and im about to throw it out my window lol.  PLEASE AND THANK YOU!!!!!

How old is your Dell computer??? If it is above 1 and half year old then its time to throw your dell, since Dell computers works perfectly for 1 and half year or maximum 2 year, after that it started giving you problem. So don't worry, just throw it out of the window since one day we have to do it, so do it now.....LOL
