Computer crashing, losing signal to monitor

  1. Hi guys,

    So I have just gotten this pc for work about 4 weeks ago, and probably the past two week it keeps getting a black screen at random times saying 'no signal detected' I can still hear any music, games etc I may have in the background fine. I find it happens faster if I'm on a video game ( I only play hearthstone on this computer though because as I said it's mainly for work). Basically what happens is mainly when playing games (not all the time though) it will usually get a bit laggy than the screen will go black saying it has no signal and sometimes I singular beep will go off (just like when you turn it on) again not always though. Usually I can press the power button once and it turns the power off, turning it back on it starts as if nothing happened, no errors, no warning saying it had a force shut down, just starts like it is fine.

    Again this a basically a brand new computer so there won't be a dust build up, I posted on another forum and someone replied with just claim it on warranty, problem is this has a bunch of sensitive work files on here and I really don't want it replaced.

    As a side note, we use maximum titanium security suite on our computers, it is apparently really good and has shown that nothing is wrong on it, I downloaded malwarebytes and did a scan it didn't show anything as well, I also have just done a ccleaner on it today, it cleaned the computer up but issue is still current. Any help would be much obliged, thanks.

    Have you tried using another monitor?

    No, but I dont think it would be the monitor to be honest, Yeah it says no signal on it, but when I restart it everything displays fine, also seems to happen more often to games.

    It would be wise to try a different monitor first to rule it out... an easy thing to do

    Okay, good. It has to be a problem with the video device. Is this a laptop or desktop PC?

    If you are running on-board video you might want to invest in a video card...
