Monitor sometimes lose signal while gaming

[ZhaiNo1]

Hello guys, I have recently built my own PC with the following spec:
CPU : i5-6500
Mobo : MSI-B150M PRO-VDH
RAM : 8GB (2x 4096MB) HyperX FURY black DDR4-2133 DIMM CL14-14-14-33 Dual Kit
PSU : 500 Watt EVGA 500B Non-Modular 80+ Bronze
GPU : 8GB PowerColor Radeon RX 480 Red Devil
On several gaming occasions, namely while I was playing DOOM (1080p maxed out) or Civ 6 (1080 maxed out), my monitor suddenly turned black and said "No signal", and the fans started blowing like crazy for 10-15 secs, while the GPU's temperature was still stabilizing under 70 degree Celsius (167F). The only solution was to force a hard restart. Would really love some advice here. Have already tried reinstalling the GPU's driver. Should I try updating the BIOS also? And if this keeps occuring, will it shorten the lifespan of the GPU?

What GPU are you using?

I would try the easiest solution first and try a different dipslay port or hdmi cable.

Sorry, just updated the info for the GPU. I thought of that as well but it does not explain the fans going crazy, right?

I agree, the fans are strange, but that could just be when you notice them. I mention the cord because I had a very similar issue once, so I tend to look at the cord first.

What type of fan curve do you have on? Your fan speed will increase when your card gets hot. If your fans are set to 100% when the card gets to 70C they will speed up and get loud.

You said that the fans run for 10-15 seconds until the card stabilizes under 70C. What is the temp of the card before the crash?

You may have an unstable overclock. If your overclocking, I would set it back to factory defaults and see if it happens again.

Maybe it was my phrasing, but what I meant was 'before the signal lost, the card's temp has been constantly under 70C'. I don't do OC at all, so that's not the problem. I'll probably try getting a new cord, but I don't think it will solve this.

Try changing the cord as it could be the simplest issue.

You said that you installed the driver to the GPU, I would make sure that you did a clean install of the driver. When you download the driver, select custom instead of recommended and a box will pop up at the bottom asking if you want a clean install. Choose that selection.

If none of those work, I would see if I could try the card out on another system. This will tell you if it is the card or the system.
