My laptops specs
HP pavilion dm4 1009tx
Windows 7 (64 bit)
intel core i5
Ram 6 GB
intel HD graphics and ATI radeon 5450 HD
Problem I am facing
Laptop has been working fine since three years, just few days back its ATI radeon 5450 HD graphic card crashed ( screen gone black ) while playing game called second Life. I had to manual restart in safe mode to disable ATI graphic card to just use intel HD graphics to be able to see anything. In safe mode I cleaned old AMD graphics drivers with driver sweeper and tried reinstalling drivers in normal mode. Installation starts, it recognizes card and when there comes point where it says screen will flicker, it does flickers one time and display comes back with installation still going-on on screen and it again flickers for second time but screen stays black this time. I again have to manual restart to go into safe mode to uninstall and disable ATI to be able to see anything in normal mode with just intel HD graphics card. Same thing happens when I try to install factory driver (one that came with laptop) or driver (from HP support site, same as factory driver) and I even tried new drivers from AMD site for this card but same result. Though I think factory drivers from HP are most relevant because AMD don't support those cards in HP laptops packed with intel HD card for switchable graphics.
When no drivers installed In device manager ATI card appears as Video Controller (VGA Compatible).My guess is card over heated and crashed but since its still detectable as a hardware by device manager, my Question is, is it a dead hardware ( or even zombie) now and I am stuck with it as graphic cards of notebooks can't be changed ? or it still can only be a software/driver issue ? , Any idea how to fix it ?
Please help I want to keep using my this laptop for lite games such as second life. Thanks in advance.
