Windows 7 64 bit crashes when change wireless network

[moschops77]

Hi, hope someone can help me.

I have a relatively new laptop, Windows 7 64 bit. I work from home and my laptop automatically connects to my wireless network fine. However, when I try and change the network I'm connecting to, everything crashes, in fact the network centre and options don't even load. It's weird, even if I place my mouse cursor over the wireless signal icon in the bottom right taskbar, the computer freezes! That's without me clicking anything... I can't go and visit clients now cos I cant connect to any wireless network. I'm sure my laptop used to be fine with this so I don't know what's wrong or how to find out...
I have tried installing the W7 SP1 update but it won't install...
Any help MUCH appreciated!!!!

To test for corrupted system files - put your w7 install dvd in the drive first - so it can copy the files if need be.
Next click start - type CMD in the search press enter - right click and select run as administrator - type this in the window SFC /scannow and press enter.

try to repair your windows then if it still crashes try to check your updates.
