I have a laptop - Dell Inspiron 2590 with Windows XP. I went to Dell- Support online to check if there were any updates to drivers, bios, modem drivers, etc. They listed about 11 of them - but how can I scan my computer to see what I have installed? Is there an easy way for a site to scan my computer and tell me what is installed and the version. I don't want to download something that does not pertain to me.
