Board index » Windows Vista » Windows Aero scheme not available

Quote

I have been using Windows Vista Ultimate x64 on this machine for about 4

months with no problems. Last week I had a crash that led me to clean

install it all over again. Now I just see that Windows Aero scheme is gone.

It doesn't appear on the list under Apearence Settings.



I noticed that going to Performance Information and Tools gives me a rate

of 1.0 (which I think is untrue, my hardware specs are below). I tried

reinstalling my graphic card and sound cards with no success. Even tried

that registry tweak (set HKCU\Software\Microsoft\Windows\DWM\Composition =

1 and HKCU\Software\Microsoft\Windows\DWM\Composition Policy = 2) with no

results.



I noticed this 1.0 rate is determined by Gaming Graphics (1.0) followed by

Graphics (1.9) which I believe is too low for the hardware I have. After

Update My Score, I click on View And Print Details and I notice that

windows hasn't detected Total Available Graphic Memory nor Dedicated

Graphics Memory nor Shared System Memory. BIOS gives me 3 graphic memory

sharing options: 64mb, 128mb and 256mb. Tried the three of them.



Again, before I had to reinstall Windows Vista, it was running perfectly

on the very same machine.



Any help will be apreciated.
