PC shuts down when playing games + wont turn back on

tommybc · Jul 6, 2014

I built this computer 2 years ago and it has been like this for a while it will turn off when I am playing games that require some power, but never does so for weak games, it never shuts down during anything else though. the graphics card only ever reaches 86C degrees . when i play games such as l4d2 it turns off after 15 minutes and i must unplug the psu cable for 10 minutes before it will turn on again, maybe i have some power cables put in the wrong areas?

Sounds like a PSU issue. Which one do you have?

tommybc · Jul 7, 2014

it's a gigabyte gt odin 800w http://www.gigabyte.com/products/product-page.aspx?pid=2490#kf these PSUs look good quality to me though, so maybe it is another reason?

That PSU looks like it's for expert tweakers- are you one? If not, have you messed with any of the settings? It definitely sounds like a PSU issue to me, and while it does look to be of good quality, that doesn't mean that it can't fail.

ddferrari :

no ive never changed anything in the bios or other settings but i got it off someone else so maybe they did

Well its a good psu but it is 5 to 7 years old (rough guess) which is pretty close to the lifespan of a psu imo.

would gigabyte let me rma it or is it too old now?

Maybe it's because I wasn't using the blue or red modular connections? I was only using 2 normal modular connections for the power supply connectors and for the 4 Pin molex cables, then I used the cables built Into the power supply which were the CPU power 24 pin, fan pin, and 2 6 pin pci cables which I connected to the gpu, but maybe I should connect the gpu to the red and blue connectors on the power supply? The reason I haven't is because I don't have them modular cables to connect power supply to gpu, but before I order em do you think that would make any difference in preventing the pc turning off while gaming?
I have been lent another 700w power supply and it's working good so far but before I order one myself do you think what I mentioned above would fix the psu?

causing too much strain on the built in cables area maybe? if i if i plugged in the gpu cables into the red and blue modular inputs it wouldnt turn off as maybe less strain?

Have you overclocked?

I don't think rma is an option any more.
I also don't think that the cpu/motherboard connections are on the same rails as the gpu=pcie connections,but you could try to use the other cables (red/blue) to see if it will help.You could even mix fixed and modular.

tommybc · Aug 2, 2014

no never,

i used the red pci e connections which look like they are on the same rail as cpu/mobo as you can see in this picture, it only turns off when gaming so maybe its because theres too much stress on the same rail as both cpu/mobo and graphics card are on same rail?

Vic 40 · Aug 2, 2014

Coming out of the same place in the psu doesn't mean same rail.Have you tried the other pcie connections?

tommybc · Aug 2, 2014

not yet as i dont have any other pci connectors, but before getting them i wanted to know if it was a waste of time to get them, do you think it may solve the problem? also im in EU so it may be a little difficult in getting the right pci connectors

Before buying unnecessary parts lets try this,

Download the next program,

http://www.hwinfo.com/download32.html

You can open hwinfo32,after that open the sensor window by marking sensors=V,after click run,,then click at the bottom "Logging start" ,after that choose a name and place for the log.like Hwinfolog at your desktop.Leave it open and do game/stresstest or whatever you do until a crash.The log will end at that point but will be saved.
After the restart upload the log to a site without to much crap (!),for instance http://www.zippyshare.com/ (not the best as well), and leave a link to it here.You could also look at the log yourself with either excel or libre office calc.

here you go, i looked at it but i wasnt sure where to find the error https://www.dropbox.com/s/erxy21slk2pzl7w/Hwinfolog.CSV

Vic 40 · Aug 3, 2014

I looked at it as well and see no problems,not at the psu side or otherwise.In the end these are software readings,what are the values for the +12V/+5/3.3 rail in the bios?
The gpu only gets as hot as 86°c you say?That's the only thing that's creaping up when looking at the data.
Looking at your problem can it either be psu or gpu.Can you swap parts? Maybe lend from a friend ...

tommybc · Aug 3, 2014

im not sure could you tell me how to check the values?
yes usually no hotter than 86C
yes i tried out an ocz 700w ands it didnt turn off once
here is another reading, the first one went on fror much longer as i played skyrim first which wouldnt shut down the pc (so i switched to WD), but in this test i played watch dogs only and it turned off after 5 mins https://www.dropbox.com/s/erxy21slk2pzl7w/Hwinfolog.CSV

tommybc :

In that case it seems to be the psu,don't bother with buying extra cables,i don't think that will help,just look for a new one or if you cannot afford it a good second hand.

The gpu get's up to 89°c according to hwinfo which still is 8°c under the max of 97°c given for the card,but can you clean it just to get the temps a little lower?

tommybc · Aug 3, 2014

will do, that's what i was thinking all along but i wanted to be extra sure, no prob ill clean it and will let you know of any updates on temps
