After 2 - 4 hours my laptops starts showing me a black screen when I click somewhere. This has happened many times, and it happens only when my laptop is awake for a long time and a lots of tabs are open. (Firefox and multiple terminals in diverse workspaces) I do suspend it for 5 or 10 minutes by closing its lid. This problem happens more when multiple terminals are open. Also fans of the laptop makes so much loud
Machine info:
Acer Aspire 5742
Intel Core i3-370M
4 GB ram
Intel HD graphics
Triple boot (Ubuntu Mate 16.04, CentOS 7, Windows 7)
The time has reduced to one-half to one hour. It is getting worse, I can't do any work. Is it a hardware or software problem?
I posted it here too.
Also now it is getting worst and it shows me black screen after 15 or 20 minutes.I have found so many logs in /var/log
which mentions time when black screen shows off,but they are too many i didn't understand them.I don't think that it my screen problem as when black screen shows off,The song in my headphone Also stops playing!!

I am using Linux mint XFCE 18.2(which is in other words is Xubutnu) and I am not getting this problem.I am using Linux mint XFCE. since one month.Also I was not getting this problem in Ubuntu unity.Thus I think that this is not my hardware problem but is related to Ubuntu mate.
