My Dell Inspiron N5010 laptop is a little under a year old now. It came with Windows 7 x64. When I first bought it Windows Aero was working fine. Anyway, it got infected with trillions of viruses (almost literally) throughout the year, many of which I was unable to remove without damaging boot files. So I decided to reinstall Windows.
I mistakenly installed a 32-bit copy, and when Windows started, the resolution was very small by default. I can change the resolution, but every time I start it the resolution is wrong again. Also, if I select an Aero theme, it just doesn't do anything. So I installed a 64-bit copy and the same issue is present. I can't imagine what the problem is since it was working correctly when I initially purchased it. Can someone help me?
In addition to that I'm also unable to find any networks without an ethernet cable, even though I always had wireless capabilities before. Is the malware still affecting it somehow?
