If you are getting blue screens of death about memory errors, then you may need to run a diagnostic on your ram.
I am not sure this is acually caused by the gamemode, it could be corrupted cache issue though, try deleting your dua cache files. I am not saying all crashes are becouse of your computer, just that if your getting blue screens of death, that is usually caused by one of a few things (hardware issue like memory for example, or corrupted data on your drive).
Another thing about this, this has started recently. Started even before the last few hot fixes we pushed. This makes it seems like it could be a valve issue.
I will try and do more resurch on this.
Also, there is allready a topic on this, so dont duplicate please.
Here is the other topic:
