So recently, i updated my driver for the 4870 and all hell started after that.
When i go to Aero theme with Win7 64-bit , the windows lag when i minimize/maximize and the screen lags when i scroll up and down on google chrome.
To resolve this, i switched to Win 7 basic and now it looks so ugly.
And another big problem annoys me....
I have my computer go to power save mode/ sleep mode after like 5 minutes. If it's like 20 minutes idle and then i wake the computer back up, my main screen is black ( 1920x1080 ) and my second monitor is fine ( 1280x1024 ) . So i have to do ctrl+alt+del on the main monitor and colors appear again, but it is reset to 1024 x 768 automatically. I didn't do anything! I have to restart to revert back to 1080p on my main monitor.
That's a major driver problem all right. Uninstall the drivers, and run Driver Sweeper, or Drive Cleaner Pro. Of course, follow the instructions. After you do that, install the more recent drivers and you should be good to go.
