Windows XP PC question

[figmo]

I have this Lenovo 3000 N200 running Windows XP Pro. When I'm using Firefox (3.0.4) it sometimes totally hangs. I have noticed some of the wedging occurs when it tries to access particular sites, but even blocking them has not stopped it from trying to access these sites and has not stopped the hanging.

The performance of this computer also seems slower than that of my Compaq Presario 6000 running Windows XP Media Edition. The latter system doesn't hang when running the same version of Firefox. I would have expected the Lenovo (the newer system) to be the faster of the two, but it isn't.

Some comparisons:Chip: Intel Pentium Dual CPU T2390, 1.86 GHz, 1GB RAM

Lenovo system	Compaq system
Windows XP Professional 2002, Service Pack 2	Windows XP Media Center Edition, Service Pack 3
Chip: AMD Turin 64 Mobile technology MK-36, 2.01 GHz, 1.93 GB RAM, Physical Address Extension

I am aware that the whole GHz thing can be irrelevant when you're talking about different chips, so I don't know which chip is supposed to be faster. Any advice on whether I'm doing something wrong or if indeed my perception is correct would be appreciated, as well as any way to keep Firefox from crashing.

This may also totally have nothing to do with the issue: But the Lenovo is not upgraded to Service Pack 3... that seems a little strange for a 'newer' system, even if it does have 'Pro' on it.

There were a number of crash-related and security-related things in Service Pack 3.

Be warned, however, Service Pack 3 can be it's own pain in the sometimes, getting it downloaded and installed, especially on a laptop. And it takes a serious amount of time.

And lastly, this may NOT solve your problem at all. I would go look at those release notes that tsjafo mentioned.
