G73JH diminishing performance overtime/ broken gpu

Georgc
Level 7
I have a G73JH and when I play Battlefield 3 on the lowest settings I get maybe around an average of 30 to 40 frames per second. Over the course about an hour I'll lose maybe 5 to 10 frames per second and it'll be barely scratching 30. I want to know if my GPU is fried or broken and if there's anyway I can find out. I have reinstalled numerous drivers and I have also reinstalled Windows and it still the same performance problems. I laptop is out of warranty so hopefully I'll be able to fix this by myself so if anyone is able to help thanks.

1) What are your CPU and GPU temperatures at idle (no programs running) and while gaming?

2) Do you blow out your fan intakes and exhausts with compressed gas as a weekly maintenance routine?

3) If you remove the battery from your laptop, does your FPS remain constant?
