I installed Half Life: Source from Steam and it worked brilliantly, only problem I noticed was it didn't show the intro Steam Logo, played the sound, but no video. Didn't care, the game ran. However, the next time I went to play it, it didn't work, it would play the logo sound (No vid) like before, but then it locked up. It does that every time now. I even uninstalled it with Steam and tried reinstalling it. Has anyone had this issue? Anyone figured out how to work around it?
