It has behaved fine since 10th Feb. but this morning the display exceeds the screen, so I have to scroll to see everything.
I tried the same as last time - uninstalling the graphics card and when it rebooted it had reverted to 800 x 600. When I try to change it to 1680 x 1050 again, all the icons are fragmented. Having rebotted again it's gone back to 1680 x 1050 again with the display exceeding the screen - so back where I started!
This wretched problem keeps re-ocurring. Having gone for many week with no problems, it started again.
I tried uninstalling the device (in device manager), uninstalling and reinstalling the latest software from AMD (for the ATI Radeon HD4650) - all to no avail.
I tried removing the graphics card and running with the onboard graphics - stable but noticeably inferior.
So, I have reinstalled the card and the software but it will not fit the desktop when the settings are at 1680 x 1050 (which is what it should be). Furthermore, the ATI Catalyst software doesn't appear anywhere, despite having been re-installed. So I can't try to setup the display using that.
Really frustrated by this, can anyone please help?
Don't really know much about Graphic cards but if the computer runs ok without it it looks like the card must be at fault. So maybe a new graphics card required. Have you tried deleting the driver and letting Microsoft renew it or does that not work either.
