Yeah I had a HP with same prob, you need to open the intel install exe with winrar or something so you can get the actual files, then you need to manually tell windows to install the drivers, you only need to do this once as further drivers will install automatically This worked for me but it might not for you so proceed at your own risk eg you could end up with a expensive brick but hey it worked for me
From a previous post.
Also Assassins creed works at about 10 fps border-line playability if all settings are low (you can get a few more fps by changing some of the advanced setttings in the configuration files via notepad) also to get it to run at all you need the edited opening files or the game will just hang at the intro menue refer to previous posts for solution/fixed files.
Good luck
