Might be sound card related. What sound-card do you use?

Screenshots could help if they refer to any particular thing, like a driver failing, or something.

I don't know really, it could be caused by many things. It looks/sounds like a general underlying system instability from what you say, and what those screenshots show. I wouldn't suspect PR as being the underlying fault here, more like drivers, or hardware problem.

Some things to try:

Look for updated drivers, particularly for the sound hardware.

Disable the soundcard in Device Manager under "Sound, video and game controllers", then run PR to see if it still crashes.

If you're running any overclocked hardware, revert it to default.

If you happen to have another PSU you could use on the machine, try that instead.

If could be worth while running an extended memory tester overnight to check for errors there.

Run something like multiple instances of Prime95 on the machine to test for stability, or any program that will stress test the system for errors.

I have no sound card. Im using one that is integrated with MB. Screenshots of BSODs are here: ImageShack Album - 6 images

I'm guessing you're using Realtek onboard audio then, whichwould almost definitely the cause of your BSOD.

As boris said, you can test by disabling the soundcard completely in windows/BIOS then playing (without sound, of course).. or if you have a cheap USB-headset around that will bypass the soundcard and should abate the crashes.

There is no known driver fix that I know of, I just bought a cheap Xonor card for about $25USD and it works flawlessly.

What's happening when it freezes? Does the mouse cursor also totally freeze? Does audio freeze (e.g. start looping)? Can you alt-tab out when it freezes, or ctrl-alt-delete to task manager, or does the whole system lock up?

Does it do this when playing Coop, and when playing on an empty local server? We need to identify areas that act differently here to try to narrow the problem down.

Could you paste the full PRLauncher > Support info here too, please.

If you haven't done so already, make sure that you're running all the latest drivers for the mobo/cpu.

It could be worthwhile resetting the BIOS so long as you're OK with reconfiguring it afterwards (usually a pretty straight-forward affair).

Try disabling the audio card in BIOS.

Check Windows Event Viewer logs for error/warning info.

Try "Low" quality graphics settings.

For the entire system to lock up like you say, and produce those major errors, I'd suspect it has to be something pretty heavy going haywire, like a system bus hardware conflict, or driver failure or similar. Still, no real clue here what's going on as yet though...

Try playing vanilla BF2 online multiplayer, and see if the same bluescreen/crash/freeze event occurs.

I agree with Boris, this is almost certainly some serious driver/hardware issue, unrelated to PR.

Good stuff, thanks for letting us know. And it's no waste of time at all - it just takes a while to figure these kinds of faults.
