Does Microsoft Vista have any serious problems?

I have been using Microsoft Vista for one year now. Luckily I have had no problem at all! I quite like it. I think, we need to upgrade our system in order to have a smooth functioning of Vista. I guess your computer is Vista compatible. Next, run your computer for the viruses. And remove all junk files, folders, music and video files and unnecessary softwares. Keep it simple, you can always have backups in CDs. Good luck!

No problem for single users and it is very security one

you computer is probably infected with viruses, trojans and adwares, because those will make a computer go really slow. if you have an anti-virus software, you should run a complete scan of ur system. if you dont, i suggest you get 1 asap.
