Intermittent Startup Freeze after Video Driver Update
Hi,
I am working on a laptop for someone, and I am in a bit of a predicament. When it was brought to me, I was told that the owner was having a problem where the screen would pixelate to black, and then the display would come back up with the little popup message in the system tray saying that the display driver crashed and that Windows successfully recovered from it.
So I saw that the display driver was the WDDM 1.1 driver, which was probably the one Windows found for it when it was originally installed. Well Windows couldnt find an updated one automatically so I used my trusty program DriverUpdate by Slimware, which is the paid version of SlimDrivers (I know it sounds gimmicky, but theyre a MS Gold Partner). Anyways, that found that not only the display adapter but a half dozen other drivers were out of date, such as some motherboard controllers and chipset drivers. I went ahead and made a restore point and updated them all.
After rebooting I have this problem where, quite intermittently, the machine just freezes completely during startup, at or around the login screen. I can get into safe mode ok, and so I enabled boot logging and went to look at the logfile. It looks like there are lots of drivers that are not loading, but reading closer its the display driver trying to load over and over again. The odd thing is that when it doesn't freeze, the machine runs fine for long periods of time. I was downloading and updating software, and even ran the Windows benchmarks with no problem. Needless to say, it has be a bit puzzled.
Normally I would roll back the driver, but that driver is faulty as well. Any suggestions guys? I can post the log file if you think it would help. This is an HP Pavilion dv6-1245dx running Windows 7 HP x64. TIA!
