I have a vista home premium system 2 gigs of ram and amd4600 dual core, geoforce 6150 le integrated graphics. Aero glass will not turn on. I thought it was the video card but I saw the same system running glass at best buy today. When I go to personalize color it goes to color scheme instead of the aero options. When I click on aero it loads and then unloads. 1 time I was able to actually load it up before all programs loaded up but then it reverted to windows vista basic. I heard some programs disable aero but after disabling most start up programs I still am unable to load it. Any tips?? Ithanks
