This only happens when I have TF2 running and I want to start BF2. It does not always happen but most likely I will get this BSOD.

This only happens when I have TF2 running and I want to start BF2.

Then you obviously should stop game nr1 before starting game nr2...

I cant see why you want to have 2 games running on your pc at the same time

Obviously without symbols I can't say what, but you're definitely failing in the ATI video driver here:

Since it's a minidump I can't look at any of the pointers on the stack or unassemble, but it's obvious the ATI driver expected EBX to be something other than 0x0 because 0x0 + 14 hex gives 0x00000014, which falls below 0x00001000, and any memory from 0x0 to 0x00001000 (the first 64K of process space) is all marked PAGE_NO_ACCESS and the A/V occurs and your process crashes.

I'd suggest configuring for a complete dump and providing the data to ATI support, as it's a driver issue.

Sorry for forgetting to give the following:

0X0000008E (0xC0000005, [...])

ati2dvag.dll

How can I configure for a complete dump?
