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.
