Actually there are two games both from the same company, that mak= e=20 the VM crash after starting them. Windows crashes right after starting the game. With the 1st game the=20 screen goes black as usual and the cursor keeps spinning for 3-5 second= s=20 until Windows crashes. With the second game I get to 3D the login=20 screen. The game then crashes after logging in. Windows displays this error message on the first crash: http://pastebin.com/kMzk9Jif Windows then finishes writing the crash dump and restarts. I can reproduce Windows crashing every time I start the game while the=20 VM keeps running without any problems. When Windows reboots after the first crash and the game is started=20 again, the message on the following blue screen changes slightly and=20 stays the same(except for the addresses) for every following crash: http://pastebin.com/jVtBc4ZH I first thought that this might be related to a certain feature in 3D=20 acceleration being used, but Futuremark 3DMark Vantage or 3DMark 11 run= =20 without any problems. They run a bit choppy on some occasions, but do=20 that without crashing Windows7 or the VM. How can I proceed to investigate what is going wrong?
