I have just updated to last graphics driver for my HD 4000, but PC freezes when I start any game.
I tryed to use any other tasks for iGPU, I've opened 5 HD video files, frequency was moving 350-650mhz. I think it freezes, when frequency gets to 1150.
Moved back to old driver versions. Now everything is ok. What can it be?
ASUS P8Z77-V LX (bios 0610)
i5-3570K @3.4 (TB 3.8) HD4000 @1150
Kingston HyperX 1600mhz 4096x2
Deepcool Ice Blade Pro
OSZ ZS 650W
Windows 7 x64 Ultimate
If the computer is working fine with the driver you currently have then it is not necessary to update it. If you need to use the latest driver then you can try other troubleshooting steps like updating the BIOS of the motherboard.
