BSOD at startup/wake up. switchable graphics Notebook.
Hello everyone,
I have a HP ENVY 15, 3040nr with switchable graphics (product specifics available at this link).
EXISTING SITUATION:
Switching between AMD and INTEL always happened with no problems, when you switch off the notebook it will switch back on with the last selected configuration.
PROBLEM:
Basically, few weeks (I suspect problem started after a Windows update, but after evolution of dynamics I'm not so sure) I started experiencing random BSOD at startup or when waking up the system from sleep (not hybernation), it expecially looked like that the BSOD was guaranteed when system was sent to sleep when Intel graphics were selected.
BSOD would happen, and system would restart with AMD graphics turned on by default.
FIRST TRY: WIN UPDATE. THEN FORMAT C:, REINSTALL ORIGINAL HP DRIVERS - NO RESULTS
I tried downloading updated drivers from HP for the Intel from Win Update (non existing) but problem kept showing up. I then formatted and reinstalled everything from scratch. This time I installed only the original drivers coming with the original hardware (you can find them on HP website), but the problem kept showing up.
SECOND TRY: CLEANUP, INSTALL UPDATED DRIVERS - NO RESULTS
So i formatted again and this time installed Catalyst_14.2_Beta_v1.3_UnifL, which are ad-hoc designed driver, making up for HP lack of updated drivers for this kind of device. Previous versions of this driver worked wonderfully for whole last year. They worked fine for a few days but I still got a BSOD
BSOD SITUATION:
Intel card was selected, I was cheking the screen properties on the AMD driver dialogs, and i got my Blue Screen.
FILE ATTACHED:
1)2) OLD MINIDUMP these are the minidumps from the BSOD I got before formatting. Maybe worth checking.
3)4) are DM LOG and SF Diagnostics zip files.
I will be really grateful if anyone could give it a look. Thanks in advance.
