I have a Dell Precision T5400. I've had it for several years now and it has worked very well for me. Recently, my PC began rebooting when it was idle and the power management would come on. I adjusted some of the power management settings and also ran a virus check (nothing was found) and it seemed to clear itself up for a couple of weeks. I noticed that the problem started immediately following one of the automatic Microsoft updates that occurs weekly. Anyway, after the problem went away for a couple of weeks, it has started back up again.
I checked the event log and the log shows the following error when the PC gets rebooted:
The computer has rebooted from a bugcheck. The bugcheck was: 0x00000116 (0xfffffa800a667010, 0xfffff8800fc46e2c, 0xffffffffc000009a, 0x0000000000000004). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 081714-27970-01.
So, to test if it was software driver related, I rebooted and went into safe mode. I left the PC idle for several hours and the PC was fine. It never rebooted. This makes me think it is a software driver issue? It doesn't appear to be hardware related.
At this point, I'm not sure what next steps I should take to further identify the problem and how to resolve it.
I'm thinking it might be video driver related or possibly the power management?
I have a NVIDIA GeForce GT 610 graphics card. The current driver is: 184.108.40.20623
Any help on how I can resolve this would be greatly appreciated.
