Hi!
I've recently installed the Orange Box on my Aluminium 13" Macbook (2.4Ghz).
At first, the games ran fine, but soon I started experiencing a lot of crashes (happened with HL2, HL2 Episode 1, Team Fortress 2, (haven't tried the others)). Sometimes the game just freezes (i hear a repeating sound), then quits. I get different error messages every time:
"The instruction at '0x0######' referenced memory at '0x#####'. The memory could not be 'written'"
or
"This application has encountered a problem and needs to close."
but sometimes I don't get any message (the game just quits).
Turning down the graphics settings to "low" didn't help.
I tired disabling the background programs but that didn't help either.
I tried finding some new drivers but had no luck with that...

I would appreciate your help!
Thanks in advance.

hello and welcome!
ok, first things first, which OS are you running? XP, Vista or 7 beta? and then is it 32 or 64 bit?

as to the graphics drivers, go here and choose the appropriate OS that youre running (for 7, just pick the Vista driver).
I reckon that this should, hopefully, fix it.

But, just in case, have you tried any other games and had problems?

if new drivers dont work, then let us know and well have to think of something else.

I know that this one ... ""The instruction at '0x0######' referenced memory at '0x#####'. The memory could not be 'written'" ... is definitely an error related to the video card memory. Updating drivers will help. That's what fixed it for me.

This is a good place for his thread, he needs help getting his boot camp setup working for games. If he needed help getting Internet Exploder to stop jamming viruses down his neck then yeah, Windows On Mac.

Thanks for your quick answers, but unfortunately the problem remains.
My OS is Windows XP 32-bit.

I tried downloading and updating the driver form Nvidia ( http://www.nvidia.co...9.28_beta.html) but it said my graphics card was not supported (as expected).

Then I tried installing the driver form http://www.laptopvid....howtopic=22323 .
I first downloaded the driver itself and it installed successfully (without the Modded INF), but it installed the driver for GeForce 8400M, because the 9400M in not supported (not listed). I tried running HL2 with that driver but I got the same crash..

I rolled back to my default driver (the one that came with BootCamp) and pasted the modded INF (from laptopvideo2go) over the one in the driver folder I downloaded previously (from laptopvideo2go). But when I tried installing it with the Have Disk option it said: "An error has occurred during the installation of the device. The driver selected for this device does not support Windows XP" (on laptopvideo2go it says the driver is for XP)

The problem is, I can't find any windows XP drivers for my GeForce 9400M.
I've installed Swat 4 and it ran fine. I also played Far Cry 2 and it was ok (a bit slow and laggish but otherwise ok).

I hope you understand what I've just written (i posted this already on the Macrumors forum - http://forums.macrum...d.php?t=642126) .
Thanks

Ok, I've had some progress .
I didn't get any proper results Googling and searching for GeForce 9400M XP driver, but I discovered the codename for the GeForce 9400M ( http://www.notebookc....G.11949.0.html ).
Apparently it's also called MCP79MX. So I Googled for MCP79MX XP driver and got this forceware driver: http://www.laptopvid...ivers/xp/174.60 .
It says the original INF supports the MCP79MX (GF 9400M) so I'm guessing it should be ok. I haven't tried installing the driver yet.
What do you think, should I try?

go for it, you can't make things any worse then they are now. And even if it fails with lots of fireworks etc. (which it won't) you can just download some sort of driver cleaning program to turn your bootcamp graphics drivers into a clean slate for new ones
