Recently I replaced my old Radeon HD 2600XT to Radeon HD 6770 from MSI.

I had strange problem that after installing the newest Radeon drivers they exist only until first reboot. After reboot my new card is recognized as an old 2600.

I tried to unintall ATI/AMD software completetely from Programs/Features, then reboot, then untinstall driver from device manager, then reboot, then system showed that display driver is regular VGA (and oldschool 640x480 resolutions). Then to be double sure I executed DriverCleaner3 and Driver sweeper. After the restart I installed the newest drivers from amd site but after restarting the system recognizes card as 2600.

I'm completely lost. Perhaps Win7 64bit caches somewhere drivers? Are there any issues regarding drivers-shadowing or 32/64 mirroring?

Reinstalling the system is not an option.

You could try and run ccleaner piriform.com/ccleaner – bamboon Jan 13 at 19:50
Or unistall it with: freenew.net/windows/iobit-uninstaller-2-0/68873.htm – bZezzz Jan 13 at 19:54
You SURE you didn't put the 2600 back in (have to ask)? Have you tried manually assigning the drivers to the card after it's detected as a 2600? – techie007 Jan 13 at 22:12
Best video driver cleaner there is...drivercleaner.net – Moab Jan 13 at 23:03
Yes I'm sure that newer card is inside. – tomo Jan 17 at 23:13

Download Driver Sweeper from - http://phyxion.net/item/driver-sweeper.html

Install DriverSweeper

Uninstall your Radeon drivers from the Control Panel > Programs and Features

Reboot your system into safe mode (Hit F8 during Boot)

Run DriverSweeper (from within Windows Safe Mode)

Check on "AMD-Display"

Hit Analyze

Select All and Hit "Clean"

Reboot back into Normal Windows (not safe mode)

Install your new drivers
