im using HP Pavilion dv6-6150et Entertainment Notebook PC, windows 7 64bit.I updated Mobile Intel(R) HD Graphics automaticly from device manager then its name changed Intel (R) HD Graphics 3000 and when i restart i saw that Radeon (TM) HD 6770M has yellow triangle on it and when i open properties it says "windows has stopped this device because it has reported problems". After that i updated Radeon 6770M then Intel (R) HD Graphics 3000 changed to Mobile Intel(R) HD Graphics back.And i couldnt open system properties and mozilla(these are not a big deal but it indicates there is a problem which i may not yet know).And i autoupdated again Mobile Intel(R) HD Graphics, and it become Intel (R) HD Graphics 3000 again and Radeon 6770M stop working again.i read many forums but im so desperate now.
And now i see that i cannot open some of my games .when i try colours change blues turn to red etc.
As your system features switchable graphics, this requires special drivers to work properly. In that case, the drivers that you should use are the drivers that are only provided by your computer manufacturer. You can refer to this URL to get these drivers:
yes i know.i thougt when i update my drivers from device manager it downloads from that url.When this problem occur i try manually download and install from that url.Radeon driver installed and i restart laptop.Then i try to install Intel driver it says " this system does not meet the requirements of this install"(google translated).
You may manually got to that URL and update the drivers by downloading the packages posted on Hewlett Packard's website. If still the drivers are not installed properly is suggest that you check with HP support directly for assistance on this.
