Chosen Solution

My computer recently has started crashing when playing some games. When this happens the computer screen is green and usually a loud sound comes out of the speakers, usually scaring me. Restarting the computer fixes it. I think it might be a overheating issue, for a while what I did was take off the side panel, which usually made it so the computer doesn’t do this but recently it still does this even with it off. Also quite a few times I left the computer on for a long time without it turning off, possibly leaving it on for at most a few days. Do you think doing this made the thermal paste bad or something? I really want to continue gaming on the computer which is hard when it does this. Especially on games that dont autosave. Also another issue is that the computer sometimes likes to restart without warning, no blue screen, nothing. It’s not windows because I turned it off its permission to do so. The graphics card also usually gets quite hot when I play on it. Update (08/19/2021) @aactech Is this it?

Update (08/19/2021) @aactech I’m not sure about the motherboard, but the graphics card is a radeon rx 470 armor 4G oc.

heres a few images. Also 8 GB of ram, I am using a hard drive. I had bought the computer pre-built. Heres the CPU according to windows

The computer does not shut down, I have to shut it down myself, I have not cleaned the fans, or the motherboard. Update (08/20/2021) I also found a version of the same motherboard but it has the ports that were not on the other photos I looked at

Update (08/19/2021) Sometimes it works just fine and does not do this, last night I played it for several hours without anything happening Update (08/19/2021) @aactech When I think about it, yes the graphics card does get very hot when I play games, also I looked at a few things about the graphics card earlier and saw something that now makes sense. It was saying that the graphics card was supposed to run fans at full speed when the temp got to a certain point. I looked at some temp tools to see that the fans were not spinning but according to the chart for the card they were supposed to be, which I guess caused the overheating issue. Also here are some codes I found on the motherboard.

The symptoms you describe could have a number of causes. Looking at the photo it looks dust free inside so that is not a problem. Probably more the power supply. Supermax is a very low end power supply. Also your 400 Watt power supply does not, in my view supply enough power for your system. The Radeon RX 470 Armor 4G OC recommend minimum at least 450 Watts . Insufficient power could cause the graphics card to overheat.

Or you could run programs like “CPU-Z” (less) or “HWiNFO” (more) which will give you all the information about your system. You see giving all the details about your system is very important for us to be able to help you. Otherwise, you are asking us to be clairvoyant or guess, which won’t help you very much. Have you checked what temperature your system is running at? Have you updated all the drivers?
