The main reason I wanna change my OS is because I'm getting sick of the problems I'm facing with XP. At first, all was okay but then weird things started to happen. Example: Some programs started to fail. (Apparently) Something was wrong with my service pack. (SP2) So I got my CD out and reinstalled it. All was working fine again but now afew stuff are going wrong again... Example: Some programs won't install and some games that previously installed with no problem just won't install. I seriously doubt it's viruses since my computer is always being watched by programs and I don't go near the odd stuff online. Nothing is wrong with the hardware in my computer cause (As I said) this happened before but I reinstalled XP and it ran like new with no problems. I keep cleaning my registry files and everything... But the problem first started when I did a system restore...

I have 504 RAM. For Vista Home Basics it says (512 megabytes (MB) for Home Basic) Do you think it's safe to upgrade? Or just buy an extra GIG? Even though, will it still run okay - the 8?

Hey! I wanted to know if it's a good idea to upgrade to Vista (Vista Advisor does not work anymore) Here are my specs... System: Microsoft Windows XP Professional Bersion 2002 Service Pack 3 Computer: Intel® Pentium® 4 CPU 2.60GHz 2.59 GHz. 504 MB of RAM Thanks. http://s821.photobucket.com/albums/zz137/ThisIsAExample/?action=view&current=pc.jpg
