A lot of people are having performance problems with Vista. If you do a
search on Google for "speed up vista", you'll find a lot of suggestions.
Use the ones that are suggested by lots of other people.

Do you really think that by upgreading RAM I will able to solve the
problem

It may not "solve" the problem, but more memory is /always/ good.

I heard that we need to do something in bios to get some good speed,
anyone
of you have any idea on it?

There are some adjustments that can be made in the BIOS on many machines to
adjust a system's performance. However, choosing the wrong settings can
degrade its speed. And on some computers, no such settings exist in the
BIOS. I don't know about your Lenovo machine. Generally, you should assume
that the problem is elsewhere.

The first (and easiest) things that I would look at on your computer a

1) What programs are starting automatically with Windows? Uninstall or
disable the ones that you don't need. For instance, if you have a lot of
little icons in the lower right-hand corner of the screen, they can be
slowing things down.

2) Some folks have performance problems caused by McAfee or Norton antivirus
software. Try disabling them temporarily disabling them (BUT DON'T GO
ONLINE OR DO EMAIL WHILE IT'S DISABLED) to see if performance improves. If
one of those programs is the culprit, then re-enable it, and get Eset's
NOD32 antivirus software. Reliable sources say it's better (uses fewer
system resources, detects new viruses more reliably, gives fewer false
positives).

There are other suggestions that you'll find from your Google search, such
as disabling unnecessary services, networking protocols, and the like, but
they can require some level of technical understanding of Windows.

Good luck!
