Crashing/Semicrashing on laptop (Lenovo Y580)

[Lionera]

I didn't know we could use older versions, I thought they phased out when newer ones are released. Sorry not really a tech savvy person unfortunately. How do I increase the TDR tho? Thanks btw for the advices least now I have a couple more things to work on and try

You've alot of options far as getting 'older' video drivers. To name a few archives:

NVidia's archive: http://www.nvidia.com/Download/Find.aspx?lang=en-us (back to 310.90 for mobile)
Guru3d's archive: http://www.guru3d.com/files_categori...vista_|_7.html (every release ever made)

--Sometimes you may find that a driver (not straight from the manufacturer of the laptop) doesn't support your laptop's "specific" hardware ID (a few manufacturers flash a custom vbios that alters the hardware-ID reported to the OS). In these cases the drivers straight from NVidia "still" work ... just you may need to manually add said ID to the respective driver's inf file manually. [*This part probably won't be necessary, yet I'm mentioning it incase you run into issues getting older drivers on there*]

Also note that you can only rollback drivers so far of course (to the point that NVidia first added support for your hardware). If you have a card like the one mentioned in my Sager though, you'll have no issues rolling back to R310, or even R306 / 304 if you wanted to for the sake of experimentation.

--Newer does not necessarily mean better, as the best driver is imo the driver that runs stable for YOUR specific setup and games. Newer drivers fix issues with newer titles... Yet, as the saying goes "If it ain't broken, don't fix it".. Sometimes changes to get new titles working or fixes for issues in newer games, cause new bugs or the resurfacing of issues in others.



Far as raising the TDR delay, the above section of text between the ============== dividers is essentially a registry file that raises the timeout to 10s. You can copy and paste the text between the lines in to any text editor, such as Notepad, and save that as "TDR.reg". Then right click on TDR.reg and select to merge / import the file.

Alternatively, you can use 'regedit' to navigate to the listed key [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers], and modify the TdrDelay value by hand. Just type "regedit" into the Windows start button (or screen) search feature, to find the tool. (It's included with all copies of Windows)

*You'll need to restart Windows for the change to take effect.


If you have a Windows 8 machine, the new bootloader is a "pain in the butt" to get to disabling driver signature enforcement (for the initial installation of a driver where you've edited the inf). A trick to make this alot easier is to restore the Windows 7 / classic bootloader behavior (which doesn't require multiple reboots for the F8 choice to be made).

Just open an administrative command prompt, and enter in:
bcdedit /set {default} bootmenupolicy legacy


On the next reboot, the F8 menu will be the classic.
