Alienware M17x R4(7970m) Discrete Graphics Not Detected Upon First Boot

Whenever I turn on my laptop after several hours of not using it, it boots up but doesn't detect the discrete graphics card, only the integrated one. But if I shut down the laptop and turn it back on, it detects the discrete and also integrated graphics again. Every day I am forced to boot my laptop twice in order for me to use the 7970m graphics and its getting annoying. I have all stock drivers from the Dell website, and have also tried other graphics drivers and I still have this problem. TL;DR: Discrete GPU not detected on first boot up after several hours of being off, but is detected after shut down and booted up again.
