Solved Time for a new PSU? Computer turns off randomly.

Hi all

2 days ago I replaced my CPU from a FX6100 to a FX8350, last night and this afternoon I've encountered issues where the computer randomly turned off.

Last night I was just playing Train Sim, and all of a sudden the computer just turned off, no warning no nothing, just switched off, pressing the on button didnt do anything at all, although there was still a light on the motherboard so I had to remove the kettle lead, wait for the motherboard light to go out and then put it back in and turn the computer back on. I thought it was just a random thing and hoped it would go away. But a short time later it did it again while playing train sim.

I downloaded AMD OverDrive just to see the temperature of the CPU and it was saying anything between 50c-60c which quick look on google, people said was pretty hot, so I reapplied the thermal paste and added a little bit extra just to be on the safe side. Started PC backup and the temperature seemed to stable it self at around 45-50c, although when playing Train sim for example it would actually go down to 30c-40c.

The same thing has happened again this afternoon, again playing train sim, and a look at the temperature now, its about 57-59c. So maybe I'm thinking, it's still hot? Or maybe the fact that my power supply is not giving enough power to my system?

I've got a 500W PSU and had so for a few years with no problems, but upgrading my CPU makes me think that maybe its a PSU issue not giving out enough power? Is there a way to test this at all?

I've got 3 fans attached to the case directly around the CPU, I've got a MasterCooler Heatsync ontop of the CPU doing its thing so I think theres plenty of fans. I've only had this issue since I upgraded my CPU

Edit: This has just happened again, again while playing train sim and CPU was about 30-40c

I've uploaded the below pictures, just as screens of AMD OverDrive

If the problems started when you swapped out the CPU, that is where I would be looking for the problem. You would have to get a Power Supply tester to make sure the proper voltages are being outputed.

Agree, and it is not just the voltage but does it maintain it under load, is it providing enough current without the voltage dropping.

so I reapplied the thermal paste and added a little bit extra just to be on the safe side.
One of the biggest mistakes novices make when applying TIM (thermal interface materials) is they apply too much.

The most efficient transfer of heat occurs with direct metal to metal contact of the mating surfaces. The purpose of TIM is ONLY to fill the microscopic pits and valleys in those mating surfaces in order to push out unwanted insulating air that might be trapped within. Any excess is in the way and counterproductive to the heat transfer process.

So you need to shutdown, unplug from the wall, touch bare metal of the case interior to discharge any static in your body and carefully pull the CPU heatsink fan (HSF) assembly again, then thoroughly clean the mating surfaces. I use 91-93% Isopropyl alcohol (the ~73% stuff can leave residue). You can get this at your local Walgreen or CVS pharmacy.

Then carefully apply the thinnest layer possible of fresh TIM while still ensuring total coverage over the CPU die. I use a plastic-shaft cotton swab. I cut off one end, then put a 1/2 inch bend in that end to use as an applicator (clean end with alcohol to remove any finger oils before applying TIM).

While you CPU temps appear to be fine (60°C is pretty warm, but NOT hot), I start to get nervous when CPU temps sit above 60°C for more than a couple seconds because the CPU temp can quickly spike higher and that could trigger a shutdown. So you need to keep watch.

You might look in your BIOS Setup Menu to see if a temperature shutdown threshold is set as a safety precaution. I would not set it higher than 70°C.

PSU testers are handy but not conclusive. To properly and conclusively test a PSU, it must be done under a wide range of expected loads which those testers do NOT provide. Plus they don't test for ripple which can also affect stability. So the only way to conclusively test a PSU is to swap in a known good spare, or to have the PSU professionally tested by a qualified technician using specialized [read: expensive] test equipment such as an oscilloscope or dedicated switching power supply analyzer.

So if me, the first thing I would do is fix your TIM application. Then I would swap in a spare, known good PSU.

Hi all

Sorry for getting back to you all, I've been over to Toms Hardware and I believe we have found the problem and it is the PSU, although the temperature is warm, I've been recording it for a short while and the out come was this: View image: temp

I do believe it is the PSU, I've got a new one on order and should here tommorow so I can then take it from there

Check if you have latest BIOS, 6100 and 83xx are different families of processors.

I think for now I have solved the issue, It's very bizare BUT:

Reseated the RAM (Possible Memory Freeze), gave it a bit of air
Did a full discharge of power.

All seems fine, now turns off's since. Then my new PSU finally turned up and fitted that. So, So far So Good!

Good but keep an eye on it.

Nothing at all since, Think it may of been either a RAM freeze or static buildup..
