Hi,
Whenever I am using my desktop, my monitor is disconnected and I receive a "no signal" message. I have not noticed anything that would trigger this, it happens when my PC is idle and on heavy processing demand.
Before this happens, I can use my PC for 5 minutes to 5 hours. Occasionally, this problem may not happen for a week or so and I am able to use my computer as normal.
I have switched out my graphics card and RAM since this problem first started happening, updated my graphics drivers and windows to the latest version, ran my PC on a different monitor, used different cables (Display Port and HDMI) and used all PCIe slots available on my motherboard. None of this has fixed my problem?
I do not believe that the problem is OS related because it has happened whilst I was in BIOS?
Thanks!

I didn't find the right solution from the Internet.
