Since its overheating, have you tried cleaning the fan? Here is a nice site for cleaning computers, if you search you will find many others

Overheating is generally a sign of a mechanical problem. This may help you get more use out of your current computer until you can afford another one. 

my boyfriend is an IT guy and what he says don't say "I'm only going to email and type" as if those applications are ok on a lower end computer. Browsing the web these days actually requires a fairly good computer. Web designers assume people upgrade their systems often.Frankly you should buy the best you can afford (with out doing financing with crazy interest rates!).  Buying the best you can afford is especially important if you plan on using it for a long time. Buy the latest Operating System (Windows Vista) because even XP will no longer be supported soon. Ram is extremely important and is commonly undersold. Infact if you buy a slightly cheaper computer adding more ram (fairly easy in most laptops) is always a good idea. Vista needs 2 gig of RAM (different then memory) at the very least and 3 to great.

People often complain about their computers not being able to view a certain sweeps. Often times the basic computer system (especially one low on ram) might have trouble loading a page. It could be caused by other things (like Dialup!) but having a good system is key to being able to enter sweeps.

That's my two cents from what my boyfriend has taught me. It's really up to you. Do your own research ....and I wouldn't reccommend trusting everything you hear from "box" store employees. They often aren't as educated on computers as they sound. My boyfriend frequently overhears them misinforming people and corrects them.
Good luck!
