Have 2x nvidia GTX cards in SLI. Everything up to date and has always been fine with absolutely minimal errors for years.
Computer is thoroughly cleaned out regularly and I rarely ever had any problems with anything, including GPU.
Did not recently update or change any settings in bios or windows so most likely not related to that.
Every few months I would switch which GPU I had my display plugged into so no burnout and shared workload.
Recently, the 2nd GPU was having some driver crash issues when in SLI and being main card.
No blue screens or anything, just the driver would crash and reset after a few seconds of black screen.
Plugged monitor into 1st GPU and now no more driver issues since then, but SLI no longer registers on Nvidia control panel and the 2nd GPU is not being used at all even if I allocate things to it.
1st GPU is definitely fine 100% by itself with any applications. 2nd GPU fine except driver crash with gaming or being woken from sleep sometimes, but could be related to an SLI problem here.
How to determine whether problem with SLI bridge or 2nd GPU?
I normally would just mess around with it myself, but I cannot go without a computer while waiting for parts, so want some input before I screw something up.
Thanks in advance
