Tomb Raider AOD problem

[MeekaCroft]

So I have Angel of Darkness on PC because my PS2 version was damaged and the game installs fine and I used Tomb Raider SCU with it to get the dual pistols. But when I play it after around 2-3 minutes of perfectly fine gameplay the screen turns sideways and starts flickering. When I turn off the game my computer screen is sideways as well but I am able to turn it back to normal and there isn't any problem with the computer. I'm using Windows Vista . Please help if you can. Thank You

Only thing I can think of is making sure your graphics driver is up to date.

It may be doing that because you're hitting the shortcut keys to change the screen orientation while you're playing. On Windows 7 I can right-click on the desktop and choose Graphics Options > Hot Keys > Disable, which stops it from doing that, although I don't know if this is the same in Vista.
