No problems here so far with Win7.
Have you a laptop recovery disk or partition?
If so I'd back everything up to an external drive,
or at minimum the data you want to keep.
Then use the restore/recovery media to put things
back as they were.
First thing I do with any new system is to image
it to an external 1TB eSATA.
If the bare system runs OK then it is "the usual software"
that you quote.
I note that some software like Kaspersky anti-virus
blue screens with some firewall installs, tried
both Comodo and Outpost firewalls.
A common problem is with drivers and it may be your
network driver is not part of Win7 and is out of date,
or maybe some other driver.
I use Driver Genius (could have chosen Driver Magic
- but not sure if the latter is Win7 compatible).
DM is having a field day regularly finding Win7
driver updates, about 5 for Realtek audio,
several for Synaptics mouse and KBoard drivers,
more for JMicron and Ethernet controllers, etc.
Also FREE CNET TEch Tracker is finding
many out of date versions of applications.
All on top of Win7 saying "installing 17 of 29
critical updates, don't you dare turn me off"
So I's suspect in your case something is out of
date.
Critical test is does it work if you get back to
square one, and can you test it CAT5 ADSL to a
router, thus cutting out 3Mobile BB just as a
test.
Once you get it stable you can by trial and error
find what makes it crash/freeze.
One advantage of imaging is you can make
successive images of each step, then it's
5 mins to go back a day or two.
Something restore points don't seem very good at.
