For a few months now I have been having this problem where my laptop acts like the AMD HD 6490m video card does not exist anymore.
In the device manager, since I updated both cards as said in this thread ( Laptops Installing drivers on switchable Intel + AMD graphics ), my AMD card now shows up as a HD 74000m instead of HD 6490m.
I don't know what to do anymore and hope to find help from you guys!
My laptop specs are:
HP Pavilion DV6Core I5 2410M 2.3 GHz
Windows 7 x64
Thanks in advance for any help you can provide!
