Vista - Functioning problems

I was wondering if anyone else was having this problem:

I got my HDD and motherboard replaced recently. However, the same problem is
occuring as when I did before I got the parts replaced. I am a multi-tasker.
So I have about 7 tabs open in one browser, listening to music and going
through folders and such. After about an hour of using the computer I cannot
open any more tabs: I click on the New Tab but nothing happens. I also cannot
open any folders or files. No, my computer isn't frozen.

So basically, I can't open anything beyond that point. After I continue to
operate on my 7 tabs, one by one, they stop functioning, which results in me
closing the tabs until I have only 3 open. Now I am able to access the
internet, and even open folders. After another 20 minutes the 3 tabs don't
work. So I have to close another, and another until I have to restart the
computer again.

Anyone else having this problem?

Sound like you may have something consuming memory

Sounds like you probably use the same (Let's say) 7 things most of the
time. Try it without each in turn, for example run 1,2,3,4,5 and 6 and
if the problem goes way then program 7 is leaking memory. If not try
1,2,3,4,5, and 7.

If none of this works then maybe it is IE leaking memory, install and
try Firefox, see what happens then?

I mean you could list all that you that you usually run and hope someone
knows of a problem with one of them, up to you, but I think a process of
elimination is the reliable solution.
