Sometimes, without any visible problems, a failure occurs on the computer, the screen goes blank, blinks. After 10 - 20 seconds the screen is restored. Sometimes (less often) the screen is not restored. Then a computer restart is required for recovery. This happens (1 - 2 times a day) only on two of three home desktop computers. At the same time, the same NVIDIA driver 342.01 is installed on all computers. Reliability Monitor reports the same problem every time: Extra information about the problem - Bucket ID: LKD_0x141_Tdr: 6_IMAGE_nvlddmkm.sys_Tesla2 nvlddmkm.sys_Tesla2 In the network I found messages about such failures 3 - 5 years ago and without recommendations.
