Ok, I have installed windows 7 professional and installed all of my drivers. Everything was fine until I rebooted. I have tried updating my drivers, both through driver genius and letting windows search for one. When I modify the display drivers it seems to go back to having the glass effect, and giving me the newer windows colours interface when I click on personalise. It just seems to reset and go to windows basic colour as soon as I reboot.
Its fixable, but only temporarily while my computer is still on, until I turn it off. I have tried the registry hack Hack to Force Enable Aero in Windows 7 » My Digital Life
I have also tried adjust visual effects in control panel > performance information and tools >adjust visual effects as suggested here http://www.sevenforums.com/customization/2233-aero-peek-wasnt-working-but-found-fix.html
but I can only get those options when aero/glass is working. When it goes back to basic once I reboot, I cant see these options.
I have also tried running the WEI test and nothing happens, I get a score of 5.9.
Lastly, I have tried un-installing the ATI drivers and installing the Intel drivers, as suggested here in post 3 by 'dw96' http://www.sevenforums.com/customization/23498-aero-theme-issue-dell-studio-1555-a.html
. When I click the setup file, it just says "your system does not meet the minimum requirements to run this software" which I found odd, given my WEI score. Perhaps it was because my motherboard has P45 chipset which was not listed in the readme, but it does say it supports all of the Intel series 4 chipset family.
I have run out of ideas, and I've almost submitted to the idea of using non-aero themes although my system is quite capable. Any more ideas would be much appreciated
