Greetings everybody! I'm a long time lurker so I know that this is one of the only places I can find some help on the topic.
Here's the deal - the wife bought a Lenovo Y40-70 from the US a year or so ago, brand new, and it worked like absolute shyte right out of the box. I don't know when exactly the GPU had a change of heart, but one day I took a look and saw that the poor computer never actually used the AMD GPU. I have since spent around a month trying to get this little ah heck to work to no avail.
Tech details:
If i install the gpu drivers provided by Lenovo, they install properly (no errors during install) but the device manager still shows the card with a (?) albeit with the R9 275 name. There is always a second unknown device marked as PCI device which has the same HARDWARE_IDS as the R9 GPU. When i try to open the CCC Panel it tells me that there is no AMD device or the drivers were installed incorrectly.
If i install the latest GPU drivers from AMD, they install properly but the result is the same except after some time I get a lengthy OpenGL error (sorry, no screens atm). Older stable versions also lead to the same issue.
If i use the AMD Autodetect tool, it tells me it can't find an AMD card.
I've tried using using all drivers (Chipset, BUSes, GPU, Audio and etc.) from the lenovo site for this model (all OSes listed below) and I've tried hunting down the drivers from the manufacturers (mostly Intel).
I've scoured multiple forums for hours and hours and I have yet to find a solution, please help
P.S. Is it possible that the GPU has went *poof* but yet somehow windows can tell what model it is?

Tech details:
- Lenovo y40-70, the warranty doesn't count outside the US so no help there.
OSes tried - Win 7, Win 8 (it came with it), Win 8.1
GPU - R9 M275
Tried clean install/uninstall of drivers, tried safe modes, tried using the AMD uninstall tool.
Replaced the HDD with a brand new Samsung SSD and installed windows fresh just in case there was something on the drive that was messing up.
I opened the laptop and the fans were clean, nothing seemed burnt or out of place.
