Shutdown During Gaming, PSU overheating? [RESOLVED]

post #1 of 26
Thread Starter 
Computer shuts down while I'm gaming (as though I've pulled the power cord). My first guess was CPU/GPU overheating, but temperatures seam OK (max 60/80°C). This and the fact that I can't turn it back on unless I switch off the PSU has lead me to suspect the PSU is overheating. I also noticed that the PSU fan isn't spinning at all. Some online sources suggest this is normal for some PSUs though, since the fan only run when needed.

So what do you think? Is it the PSU, or something else?

Sorry for brief description. I'll add More info tomorrow. I'm writing this from my phone.

EDIT:
  • MoBo Asus M4A77
  • CPU AMD Phenom II X2 555 Processor 3.20 GHz
  • GPU XFX ATI Radeon HD 5850 [image]
  • RAM 2x Kingston 2GB DDR2-800 DDR2 SDRAM (so 4GB in total)
  • PSU AXP-630P12P (630W)
  • HDD SAMSUNG HD103UJ (1TB), ST3320820AS (320GB)
  • Others 120mm Case Fan, Optiarc DVD RW AD-5170A, Case Front Card Reader
  • OS Win7 64-bit

RESOLVED!
IT WAS THE PSU!

Check following temps:
CPU
GPU
GPU VRM's
GPU Memory IC's
GPU PCB
Motherboard system temperature
Motherboard VRM's
Motherboard south bridge controller

Ensure you have all latest chipset, motherboard controller, GPU, audio, USB drivers installed and set BIOS to stock values.

Welcome to OCN

It would be much easier to help if you would list your parts

i believe your PC could also shut down if your PSU isnt enough to handle the components your have inside. If you dont have enough power going to your components it wont stay on and when your gaming you use alot of watts compared to idle and you said that when your gaming thats the only time it shuts down. i dont personally think its overheating but i cant say so for sure because i dont know much about this specific scenario.

There can be many factors that could cause these symptoms: PSU, Memory, type of software you're running, increasing CPU and/or GPU temps...faulty components.

My gaming rig, specifically my GPU (I have a HD-7990) goes into overdrive when playing Battlefield 4 - it's a demanding game - so I've actually installed an additional 120mm fan to play it safe. Anyways check out this video I just found for you, I hope you'll find it helpful: http://www.youtube.com/watch?v=tiqkPRtzu70#t=85 smile.gif

First of all, when I came home today I opened up the casing and cleaned CPU fan and heat-sink and what I believe is heat-sink for CPU-VRM's.
I tried to do the same for GPU but gave up after I realized opening the plastic shell required separation of heat-sinks from chips, and I don't have any thermal paste at home. I also opened up the PSU and cleaned out the dust.

After this effort I played the usual game for two hours. I left the casing open to be able to monitor PSU fan activity and recorded temps using HWMonitor. The PSU fan did in fact start spinning after a while. Here are the temperatures following the gaming session:

It's a little hard to make out what reading is associated with what component. Feel free to suggest alternative free recording software, preferably with logging capability so I can capture the full temperature history leading up to the crash. The 128°C temp on the motherboard is obviously false reading, since it always displays the same, even after cold start.

There is a small possibility that today's cleaning did the trick, but the problem has been somewhat unpredictable in nature. Sometimes I have played for several evenings without problem, and sometimes it happens twice during the same evening. The game I'm currently playing is Kerbal Space Program, which I don't think is all that graphics intensive, and it even happens during building stage which shouldn't be demanding at all.

I'll do this tomorrow. Need to get some sleep.

Thanks for the response. I followed the instructions in the video and determined my power usage to 340W.
My PSU is an AXP-630P12P (630W), so lack of power should not be the problem unless it's broken.
Also, what temperatures are we talking about when you say your GPU went into "overdrive"?

I worked my way through the device manager tree using "Search automatically for updated driver software" and everything was reportedly up to date. Is this a reliable method?

I haven't really messed with any BIOS settings besides booting devices.

You should not keep that PSU

Do you mind elaborating on why? I'm not going to buy a new PSU unless I'm fairly sure it is the source of the problem.
