I'm having similar issues with a Gigabyte GTX 1050 Ti LP in a Optiplex 9020 SFF. During gaming or hard GPU usage in general graphics output sometimes goes black. I think I've found the direct reason for these crashes to be the temperature sensor in the GPU sometimes giving up on me, reporting a constand temperature in the 30s while the real temp is clearly much higher. Leading to constant high voltages and GPU frequencies, a very low fan RPM, and eventually the screen goes black. I've been thinking the issue was with my GPU, but maybe there's a more general problem with this Dell + 1050 Ti combo. Did you have yours in the PCIe 4x slot?

What problems were you having with the 1050?

I bought recently a second hand Dell Optiplex PC with a Gigabyte GTX 1050 Ti card, and unfortunately there appears to be problems with the graphics card: a) With irregular intervals, varying from a few minutes to many hours, screen goes black for a few seconds. This seems to happen mostly when the system is lightly used, on the desktop, in a web browser etc. b) A handful of times during gaming the graphics card has given up completely. Screen goes black, I remember once hearing a small "pop" in my headphones. The PC doesn't shut itself down, but I do believe it's in some kind of a "crashed" state. A restart returns things to normal. c) Using CPUID HWMonitor I've noticed a couple episodes where the GPU temperature sensor is clearly not reporting correct temperatures. Resulting in a GPU happily running at max frequency and voltage, with the fan barely running. The reported temperature is a stable 37 degrees C, but opening up the case and touching the plastic GPU heatsink cover it is obvious that the GPU is much, much hotter. But a restart will return the sensor back to normal functioning. I believe this issue (c) may be the cause of the b) - type of crashes: A faulty sensor resulting in runaway temperatures eventually bringing the GPU down. -- What's the problem here? I'm running the latest drivers from Nvidia, and with regards to problem a) I have tried two different DP cables and a DVI cable - with little luck. The GPU is connected to a PCIe 4x slot as there's not enough room in the 16x slot, and availability of power may be part of the issue (This is a 75 TDP card with no external power input). But when the temperature sensor is working properly, which is 99% of the time, the card will happily run for hours at whatever frequency and voltage is possible while keeping within the termal limits (the card appears to want to keep below 84 degrees C. Plus lots of people appear to have no issues with this Dell + 1050 Ti-combo. System PSU is rated 255 W, but I've seen systems with this GPU and CPU (i7 4790) drawing around 180 Watts from the mains under maximum load - and I've not added any other power hungry components.
