First of all let me make this clear it's not a problem with the Laptop's LCD, I tried the display test, pressing 'D' during power on and the display was working, it showed the colors, etc.
System Specifications:-
- Intel Corei3 m370 Processor
- ATI Radeon 5470 Graphics Card
- Full HD Display
- 4 GB Ram
- Windows 7 Professional
Issues:-
- If I install ATI Graphics card driver, windows boots but in the final stage of booting windows shows the blue screen mentioning some error message about the graphics card and restarts.
- If I don't install any graphics driver manually then windows boots and works properly but displays only on an external 15 Inch monitor, the laptop's display remains blank, also the graphics card used is the Intel Corei3 Graphics and not the ATI Radeon graphics and in the graphics properties it shows STANDARD VGA Adapter.
Troubleshooting:-
- There was heating issue before and pc wouldn't start so purchased a brand new heatsink to fix the heating issue and so the heating issue is solved at least for the processor may be the graphics card is still overheating.
- Did a fresh installation of Windows 7 Professional to make sure there are no viruses or other programs creating this problem.
- The Laptop's display is fine, I tried the display test by pressing 'D' on power on and the display showed the colors, etc no problem with the display.
- I read in a forum in which someone who was facing exactly this problem and ran the Dell Diagnostic and it solved the issue temporarily, I tried it too but didn't work for me.
Need Help Regarding
- I'm not interested in getting the ATI Radeon to work, I'm okay with the Corei3's graphics but I just want the laptop's display to work, I don't want to use an external monitor. So please provide any troubleshooting tips that I haven't followed yet.
Thanks in advance.
