I have two different monitors, one's a Samsung and the other's an LG. I recently movedand had my computer mailed over. Since setting it up here, randomly both monitors will turn black and come back immediatelly, twice, with a delay of a few seconds in between. The first time this happens Windows' "device disconnected" sound is heard, the next time the "device connected" sound is heard. USBLogView doesn't show any events, Event Viewer doesn't show anything useful. It's quite baffling. Didn't have this problem ever before.
I have a GeForce GTX 460 and I'm running the 314.22 driver. I had Process Explorer running, and whenever that happened, two Intel graphics-related processes popped-up and disappeared immediatelly. The monitors however are connected to the NVidia graphics card, so that doesn't make sense. I uninstalled the Intel HD Graphics Driver, made sure to delete those EXEs, the same thing keeps happening.
It's not that the monitor goes into power-save and comes back either, because I'm using the PC at that moment. Any ideas?
