Just a heads up if anybody else experience the same problem that I encountered. I have a Dell Inspiron 15R SE with AMD Radeon HD 7730M, and for some reason, the official drivers on Dell and AMD's pages doesnt work. Windows shuts them down saying that there is a problem with the hardware, and the fan runs like crazy making you think that there actually might be a hardware problem.
However, I fixed this with a few simple steps (wasnt simple in the middle of it, but hey):
1. Uninstall all display drivers. Both for the integrated and dedicated graphic card.
2. I used the program "Driver fusion" to make sure everything was completely erased.
3. Restart the machine
4. Get the drivers not from the official page, but from this ftp-page:
http://ftp.dell.com/published/Pages/inspiron-15r-se-7520.html#TopSolutions
The ones you want are the 10.18.10.3277 (for the integrated intel card) and 13.151.0.0 (for the AMD card)
5. Install both of them, but the intel one first, and the AMD one afterwards
6. It should now work as it did in windows 8.0
So there might be some side-issues to this since the drivers are not on the regular support site, meaning they are still beta-drivers, but I havent had any issues so far, and from googling, it doesnt seem anybody else had it either. Hope this solves some problems for other Inspiron-users!
