Computer Shuts Off Randomly- Not A Heating Issue

  • 0

My computer has been shutting off (no warning, errors, BSOD etc.) after use for anywhere between instantly after start to a couple hours. My CPU was running hot so I installed a liquid cooling system which now had it down to a steady 40* idle and 45* running some simple processes. My GPU temp is around 28*C which doesn’t seem like a problem to me, and I’ve checked all the voltages which all seem to be within an acceptable range. The connections between the PSU and the motherboard all seem fine as well. I’m stumped. I’ve checked the event viewer but haven’t seen any errors relating to the shutdown. Just a couple DNS errors here and there (I’m on a university wifi and its a stupid set up that has always given me a DNS error). I’m currently using my sporadic time when the computer is working to back up everything on my HD.

Here are my specs:

ASRock 970 Pro3 R2.0
AMD FX-8350
ST500DM002
AMD Radeon HD 7700 Series
G Skill Intl F3-8500CL7-4GBRL 4GB (Single Channel)

Once I’ve backed everything up I’m going to try to update the BIOS using the update tool right in the BIOS. I know this is risky but I should note that it has never shut down while I was in BIOS or in Safe mode. Its very strange. That being said, I was never in either for long so it may just be that whatever the problem is, it doesn’t have enough time to manifest in those modes.

Any and all advice would be SO appreciated. If I can figure out how, I’ll post a screenshot of the CPUID HWMonitor that I get.

    1. Gotta feeling that all options are still open. It could be a hardware fault and although software might find it, there is possibility that it will only do so if it happens to fail when the software is testing it.

      If it is an intermittent hardware fault then often trial and error is the only way forward. As you are clearly at home within the box then it would be worth cleaning the RAM edge connectors with a soft pencil eraser. You then pop the sticks in and out a few times to clear any oxide off the sockets. Same applies to the edge connectors for any add-on cards. Edge connectors can often cause issues, even though they look good.

      Trying one RAM stick at a time in first position might prove something although it will limit use a bit. There is a RAM tester here with a free version:

      Always pop back and let us know the outcome – thanks
