Try to run with admin rights.
That's weird, actually. All these errors shouldn't produce game freeze, since different PhysX version isn't so important and 8600 definitely has more then 128Mb VRAM and Shadermodel 3.0 as well.
Hmm... perhaps too many tasks/processes on background? AntiVirus software?
admin rights? =>There's only 1 user account on my pc so?
I have AVG antivirus (free edition)
I quit all tasks when playing
plz advice..
