|Thank you kuwese and jam,|
I downloaded all drivers from Acer site except Bluetooth and touchpad (I do not use them). All drivers I installed without problems. Only that shinked pictures bothers me - I work with graphic.
I scanned system with DriverWhiz and Doctor Drivers, they didn't notice problems with Display driver (ATI Radeon Xpress 1250), but in manager device it is with yellow exc.mark.
When I go true the device manager and try to update, I choose folder where I saved my driver (yes, I unzipped it) but it gives me an error that couldn't copy some files. When I browse - file is there, I select it but it gives me same error again. If I know where to copy these files may be I can copy them manually.
