I would suggest possibly a hybrid ssd (if you can get an IDE to SATA converter) upgrade. This you can do yourself at home. Since you say you aren't a 'geek', go to ehow or just google "How to upgrade a computer hard drive". It is pretty simple, as long as you have a Philips screwdriver. Also, I would recommend a re-installation of what ever operating system you are using (probably Windows Vista) through the recovery disk that came with the machine. Unfortunately, you are not going to be able to upgrade the ram because its max capacity is the 2 GB that came with the computer. You could probably upgrade the cpu to a Phenom II N930, but an issue would be installing the chip (you would have to take apart the computer). Other than these two components, it is impossible to upgrade anything else.
