I have a 2013 Alienware 17. As soon as I install the dell support assist the fans bacome crazy and accelerated and after a whie the screen freezes and then start the acceleration of the fans again. The FPS are so inestable and low.
Sounds like hardware drivers.
Ensure, starting from the BIO, you update all your hardware/chip-set drivers from the Dell Support page.
Then, once the hardware drivers are updated. Update your Windows software.
It is known that Command-Centre may need to be UN-installed, rebooted, then re-installed. This happened to me, old version what bad.
You can also ask the nice Aliens at Alienware-Community Support. Dell also gives free support here, when they can. Lots of older hardware there...so it's good.
