I have a Gigabyte GA-H270N-WIFI motherboard with an Intel i3-7100 CPU. I am using the Intel HD graphics 630. Once or twice a day, my screen goes black for about 5 seconds, and then returns to normal by itself. I think this is a graphics system issue. I thought it might be caused by excessive heat, so I thoroughly cleaned the dust away from the motherboard and CPU, but the problem persists. If it is indeed a graphics system problem, how can I determine if it is caused by the CPU or the motherboard?

Can you replicate it? If so, post your temps here. I'm sure a resident guru here will take one look and be able to answer. I do gotta ask the generic "Are all Drivers Up To Date" question and ask how much dedicated RAM is allocated to it in the Bios? Only a Max 64GB can be allocated to it. (lol @ 64GB) How much system RAM do you have installed?

I can't replicate it, but I can answer some of your questions. I keep all of my drivers up to date periodically, including the Intel graphics driver. My BIOS says there is 256M dedicated to graphics. That seems to be a small amount. Would it help if I increase it? I have 8GB of RAM installed.

One thought just came to mind. My system drive is a 500GB NVME that is mounted to the underside of the motherboard. This puts it directly below the H270 chipset that is mounted on the primary side of the motherboard. It is possible that high heat from the drive is transferring to the chipset, and that could be causing my problem. I think I will clone my NVME drive to a 2.5 inch SATA III drive that I have in the system now, and then disable the NVME drive. The 2.5 inch drive is a ways away from the motherboard, so there should be no heat transfer issue with that drive.

Depending on what you do with your system, general use, Youtube, VERY light gaming, things of that nature, 256mb should be plenty. You could try raising it a little to see if that helps though. Glad to hear about the drivers. As for the m.2 drive directly behind/above the onboard, before you moved it, I'd like to see how things run if you exposed the inside of your case (removing the cover lol) and have direct airflow entering it. Do you have a house fan you could try? Try this at it's default 256mb and then possibly again with a little more (if you felt it justified a try)

Let us know how things go.

I am now running off my 2.5 inch SATA III drive and have disabled my NVME drive. If it runs OK this way for a few days, I will consider the problem solved.
