Hi all. I managed to fix my Orange Box problems with Portal and TF2 in this forum, so hopefully I can get help on this one. Half Life 2....a four year old game, crashing every 5 minutes (literally) on a brand new system. I have managed to fix the stability by turning off SLI and forcing the game into Direct X 8.1 mode. For good measure, I have also shut down my anitvirus (the Steam site claims that antivirus programs can mess with their games) and disabled a few processes pertaining to my motherboard (I won't list them here unless someone asks for them).

My question is this: has anybody who has had problems running this game in Direct X 9 had problems and been able to fix them in such a way that they can still run the game in DX9? I suppose it won't kill me to play the game in DX 8.1, but it's sort of frustrating having a powerful setup and having to scale back to allow the game to run.

Thanks

Specs:

Intel Core 2 Quad 2.4GHZ quad core (not overclocked....yet...)

2GB DDR2 1066 RAM

EVGA nForce 780i SLI motherboard

2 GeForce 9600 GT 512 GDDR3 GPUs running SLI under normal circumstances (supposedly these are overclocked out of the box)

All drivers current...using onboard sound at this point...Realtek HD audio (however, if anybody has any recommendations for a good sound card, I'd love suggestions...I may be pushing my power limits as it is, though)

This is the most important part. If you're straddling the maximum wattage and/or amperage, odds are crashes will happen often and will potentially mess up your computer. I imagine the reason playing in DirectX 8 works is due to less work on the part of the GPU, meaning it's not draining as much power.

Double check the wattage and the output on the +12V rails of your CPU. I do know that 9600's in SLI require at least 36 amps to function without any issues, and if you don't have at least 20 amps on 3 +12V rails, you're probably going to run into problems. As for how many watts you use, google 'power supply calculator' to see how much your gear may be using.

The max output for my +12V rails is 52A, according to my PSU documentation. I should have mentioned, also, that this is the only game I have that crashes. I run others like UT3 and SupComm Forged Alliance at max settings without any problems. From the calculators I have used (I used several, to make sure I would get a consistent read), it actually appears that I have ample power.
