Hi, I finished installing HL2 about 4 hours ago and still haven't managed to get it working correctly. When I click on Half-Life 2 in Steam I get the "Preparing the play Half-Life 2" dialog which disappears after around 20 secs and the cd drive makes a noise like it has begun playing the disk.. and then, nothing. I get no errors, nothing - it just doesn't load. However, it has managed to load once before and I managed to play, but have not been able to do it again for the last few hours. My specs are as follows. AMD Athlon 64 3400+ 512MB RAM Radeon Mobility 9700 128MB I have tried updating drivers and such for the radeon without any luck. Right now, I'm out of ideas. Any suggestions?
