laptop HP unstable

I bought a new laptop HP dv7-1020us, I uninstalled some few trial
programs, the anti-virus, etc, I installed Avast free, codec pack, all
the stuff I usually use, but everytime mi laptop freezes, I can't shut
down, I can't empty my recycle bin, it's strange normal use but it's
hangs on everytime, not responding progrmas, or folders. I don't konw,
I'm using most x64 compatilbe programs but maybe Avast is working wrong,
a friend of mine bught the same laptop and with the same configuration.
Everytime the systems crash or hangs on.
any idea?
