Hi Maria,
If you are not computer savvy I recommend that you stick with the known brands. I like Dell or Micron. Customer service is good and both have as part of their warranty on site repair for the first year. Micron's use to come with the warranty at no cost but I don't know if that is the case now. You could check for that on both web sites. I like hardware so on my home network I'm running one I've built, one I've done serious upgrade on and a Micron straight out of the box. If you build it, or have someone else build it the warranty will usually not be as good as the national brands and if you don't want to fix it yourself, warranty is important.
Sorry but I can't agree with Jego about the small computer shops unless you are just lucky to get a good one like Jego appears to have. They will usually make a pretty hefty profit on the build and the warranty is only as good as the individual's ethics. I could list a bunch of horror stories about small computer shops. I stay as far away from any of them as possible.
Brian is right. Know what you want and need and concentrate on RAM and more RAM. Clum1 also brings up good points about the monitor and all the components working together. On the national brands you can be pretty sure the components they use have been tested as a complete system.
One other comment. (No insult intended to the guys on the forum) but going to a computer store and shopping for a computer is sort of like shopping for a car when you are a women. The young male techie (why don't these places ever hire female clerks?) assumes that you know absolutely nothing about anything having to do with computers so he generally will not listen much to what you are telling him you need and send you home with what he decides you need.
Make a list, check it twice and then hit the national company web sites. Don't know where you live but in California I don't have to pay sales tax if it is ordered out of state and that pretty well covers the shipping cost.
One other thing. Be sure that any computer you buy is easily upgradable. They all aren't.
