Did you try multiple Episodes or only the first one?
I think the first step is looking for errors in the event viewer.
Please also post your dxdiag info.
Looking for errors in the event viewer
Start the game until it crashes.
Follow these instructions on how to start the Event viewer.
Open the "Windows Logs/Application" section.
Open the search dialog by pressing CTRL-F.
Search for "Homestar" without "". If you get a result, close the search window.
Right click the entry, select "copy the details as text", and paste them in a new reply.
Press F3 to see if you get more results, and if so, copy them as well.
Windows XP: Go to your start menu and click on run. Type in "dxdiag" and hit enter
Windows Vista / 7: Press the windows key on your keyboard or
click on the start menu. Type in "dxdiag" and hit enter.
Windows 8: At the start screen, type in "dxdiag" and hit enter
Now click on the button that says "save all information".
It will prompt you to save a file. Save it where you can find it.
Open the file and press Ctrl+A followed by Ctrl+C to copy the contents, and paste them in a reply by pressing CTRL-V.
