Alternating BSODs: Video Scheduler Internal Error & Watchdog Violation

Hi guys,
finally managed to try the tips above, went into BIOS and changed to onboard graphics only. So far no further Video Scheduler Internal Error. So it seams to be definitely about my Nvidia card.
Now I'm wondering, since it worked in Safe Mode (with the Nvidia enabled), does that necessarily mean that the problem is software-based, or could there still be a hardware problem that just doesn't get triggered? What would you suggest to narrow down the possible causes of this?
Also I'm curious about the other BSOD, Watchdog Violation. Did someone check the corresponding dumps as well? Since it only started occurring after I reinstalled Windows, I'm more convinced that this one is only caused by some driver that was installed wrongly. Would be a relief to find that only one of the two is a major problem...

In safe mode your Nvidia graphics driver will not get loaded so that is why the system works. It does point to it being a problem with the nVidia driver. The watchdog could also have been connected to this so my advice is to run with the Intel graphics only for a while and see if you get any more BSOD. If you do we can analyse them.

It may be that you need to wait for Lenovo to come out with a new driver specifically for their implementation of the GTX960. You could ask them if they are aware of problems.
