Hi,
A strange problem, but one i have heard about many a time.
I used to have a 6800le, and the game would crash randomly, sometimes after 10 mins other times after an hour.
I got fed up and decided to change my graphics card to sort out the problem, the graphics card that the game (HL2 and cs : source) was designed around.
I now have a 9800pro and the game will freeze and i will hear nasty scratching / screetching noises from each of my speakers, and i have to turn it of and then turn it back on, pressing restart will not work!
I used driver cleaner etc, and uninstalled drivers as per instructions. I could not understand why this would do this on both setups, especially as i have just recently reinstalled everything, i.e. because of new hard drives. The system setup is as per my sig, and i think i am using cat 5.3 drivers (the newest but one).
Everything else is up to date, and whilst running CS and HL2, i run asus probe, zonealarm, norton and m$ antispyware. I use AOL as my isp but i cannot sort out the problem, please help me!
Ian
