Acer Aspire 5251 Laptop, Win 7 Home Premium, AMD 64-bit cpu -- I just upgraded 2GB RAM to 8GB. The system recognizes it and computer is faster, but now ATI mobility Radeon HD 4250 video reporting problem in device mgr. and is reduced to lowest two resolutions. Also, I just noticed that Power settings have Sleep & Hibernate options grayed out. Otherwise performance is great.
Any ideas about the video appreciated.
