So, the machine just straight up powers off, no blue screen of death, no other output?
If so and it’s not the power supply, then it likely is some type of hardware problem that’s causing the machine to power off.
Typically only extreme thermal overloads that can’t be solved by throttling causes sudden power offs. You mention it happened even while idle. While yes, a computer can overheat with a poor heatsink interface while idle, I’d suspect that the thermal throttling should be able to reign in the CPU’s temps without having to resort to pulling the “EPO” feature. :)
Have you checked to see if the power button might be depressed/stuck or the like? Same with the reset header, though if your computer properly powers off, then it isn’t the reset button.
If your comfortable (seems like it?) with opening up your computer, you can try disconnecting the power button lead from the motherboard.
You can use a screwdriver or something similar that’s metal and conducts electricity to short the two pins of the power button on the motherboard to power on your machine, if your motherboard doesn’t have it’s own power button. (My ASUS motherboard has an on-board power button - why I mention it.) Run it with the case’s power button disconnected and see if the problem goes away.
Good Luck!
That memory percentage value is concerning.
I’m curious what the Committed values are in the details of the Memory tab in Task Manager while playing BL3. There will be two values separated by a
/
. The left value is the actual amount of memory in use, real and virtual. The right value is the amount of physical memory you have (16GB) plus the size of the pagefile.sys file.Let’s address the right value first. For example, if the right value is 24GB, then that means that your pagefile.sys file is ~8GB in size. (24GB - 16GB[real] = 8GB remaining.) We really don’t care much about the actual size of the pagefile in your case. Just letting you know what that value represents in case you were wondering.
Let’s talk about that left value. This is the single most important value, IMHO, on the whole of that Memory tab.
If it is close to or greater than 16GB (13-14GB or greater), then you are severely in need of more memory. You can try decreasing the video settings in the game to see if that’ll help. Also, let’s say that left value is 20GB - better make sure that your memory upgrade is going take you considerably beyond 20GB. This is a good “high-water mark” for the actual amount of memory that your computer uses.
If I were you, I’d greatly reduce the graphics settings (write down/screenshot what you have currently, so you can restore it) in one go. This way you can find out if those graphics settings have anything to do with disconnects. After changing the graphics settings to Raspberry Pi mode :) and you’re still getting disconnects (and memory consumption and GPU usage have decreased considerably - which would be expected), then something else is up.
