slow computer?
I bought my dell laptop 2 years ago and it's always been slow. i currently use vista, and am thinking about switching to windows 7. i was told that vista runs slow on my computer because i didnt buy enough space. will the switch alone make my computer work faster, or do i also have to add space for it to work effectively?
Your most likely issue will be RAM not "space (disk space)". Early Vista machines did not have enough RAM installed to run. The Microsoft minimums are just that - absolute minimums to get the system up.
Depending on what your hardware platform will support, upgrade to at least 2 to 4 GB of RAM and you should see an improvement.
Also you can download AdAware from Lavasoft to check for malware. If your machine is loaded with malware, popups, etc they are stealing CPU time and you will run slow.
