One other thing, this has happened when I first tried the 12.6 WHQL. As for XP, I have a LastXP dvd, so I can try that as well I suppose (I've tried it twice before the BIOS update but the result was that I ended up with a black screen).

I would like to us the ATI card, because the laptop is plugged in always (when using it), but not sure if it's the 'good' option in my case! After the BIOS update I've tried only Windows7圆4 and never the 32 bit one. I'm out of ideas? What do you think about the BIOS settings? With one should I use? Till the BIOS update I didn't have the option in BIOS to choose between discrete/inter/switchable mode, it appeared after the update. This is so messed up, I'm starting to believe the video card is DAMAGED(even though I don't understand how can it work sometimes for longer periods of time, and causing problems mostly when it's not under burden). I'm probably the most problematic guy, since not even the basic driver works for me (in discrete mode)(the basic driver installed by windows never starts showing the usual code 10 error) and afterwards even after driver sweeping/ccleaning the windows and it's registries and installing a fresh 12.6 WHQL driver, I got eighter a color screen of death (never BSOD). I've tried it in both discrete and switchable mode.

I've tried believe me, like a million times the 12.6 WHQL from amd's site, by instaling it over the default one, and even tried cleaning up previous drivers and only installing this one. (After a lot of reading into it, this is normal, since they somehow co-exist) but, and here might be a problem, the Intel shows the same driver number as the ATI when instaling the 8.64.4 and after instaling the 12.6 WHQL (over the 8.64.4)from amd the intel shows the 8.64.4 while ati 8.970.100.300 i believe) After installing the either the 8.64.4 package from acer's site or even after installing the 12.6 WHQL it shows both. The answer to your first question is yes.
