    Monitor "No Signal" randomly mid gaming

    Hello, not sure what section to post in sorry about that.

    Randomly while i'm playing a video game both my monitors will go black and come up saying "No signal" and wont come back on until i restart my computer, this only happens while i'm playing games has never happened while just watching youtube or movies.

    Thanks :)

    Edit: This is a brand new custom built pc from pccasegear so it shouldn't really be having issues

    No it shouldnt be having issues , your gpu or cpu is crapping out , you could try running msi afterburner to see what your gpu and cpu core temps and usage are in game prior to it shutting down but if i were you id just get them to fix it , , they sold you an unstable system :/ At a guess your cpu is overheating but thats for them to sort out

    Bump: sent my graphics card back to pccasegear and just got a response from them, this is what they said

    We inserted the GPU into one of our test benches and it was able to post and boot without issue. We ran the stress testing program Furmark for 15 minutes before running Valley for 1 hour and Heaven for 30 minutes all without issue. Next we ran three passes of 3D Mark Fire Strike Extreme without any issues before testing output from all five output ports on the GPU. We also restarted the system several times to ensure it was stable, all without issue.

    Hoping someone here some more of an idea what could be causing the problem, seems to happen even when the monitor is plugged directly into the motherboard.

    Take a look at the power supply?

    If this is a new PC, and still under warranty, have the company troubleshoot it.

    just get a new cable. as the HDMI spec is popping out raw data, the more data you see while in game, the bigger chances there are that the cable is badly manufactured and/or not certified. how long is it? everything past 6 feet that isnt certified might have manufacturing issue.
