Weird gpu problems[solved]

first of all I have an and radeon gigabyte 270 and it is running on default settings  

So one day after my dad was playing world of tanks I went to my computer to find it shut down  I didnt think anything of it until today when my dad said it shut down twice while playing wot so I went down there started it up and checked the temp on the gpu it was idling around 75c I then started the valley bemchmark as a test and it almost immediately shut down I then reseated the graphics card and tried again this time I monitored the temp while I did the benchmark. This time it didn't crash and it went stable around 55c I am now waiting to see if it does it again but until then I would like your opinions on to what you think it might be also now that I think about it I havnt played any really graphic intensive games in awhile anywat thx

edit: he just told me it did it again pls help

Something similar happened to me, and it turned out that my PSU was failing. a few days afterwards i got a blue screen, and my PSU completely fried itself and it had to be replaced. after i got a new PSU everything worked just fine. Your situation sounds similar to what happened to me so thats what i would point to

Are the temps up again? Sounds like the cooler tends to get loose, best thing would probably be to RMA it.

I have had it since June and it just started acting up now also is there any other signs that would tell me it is the power supply

the first thing i would do is go into your BIOS and see if you can check the voltages on the 12v 5v and 3.3v rails. If they are abnormally high or low then that just might be the problem.

when it was happening to me, i got an "asus power surge protection" message from my mobo, so look out for something like that as well.

if its not the psu then the next most likely thing is cpu or gpu temps being to high.

^^^^ good advice

Ok so I checked the voltages and they are fine and when I tested the gpu and monitored temps as mentioned in op I couldn't tell which sensor was my cup but it said the motherboard had 3 sensors and none of them got to much above 100f so I don't think its that eathier. 

Ok so as I said before I checked the 3 rails in the bios and they were fine but when I use siw under the sensors tab it appears to be much lower than it should be but I am not sure if that is just how much it is putting out at that time because it didn't need all the voltage or what but I would just like to get this fixed before it gets worse

Ok now it is doing during idle pls help I need this to stop

 

Are the fans working properly on the card?  Is there proper airflow in your system?  Is the heatsink filled with dust?

Yes yes and no but I have already decided that it is the pus based on 2 comments ago and have requested an rma from corsair

I don't see how the power supply could cause the temperature of the card to go up.

  • what are you using to check temps?
  • is your cpu overclocked and or overheating?
  • have you looked over the gpu and removed any thick dust deposits that may have been a hindrance to the fans?
  • un-installed drivers, clean then reinstall drivers (non-beta)?
  • tried the gpu in the other pciex16 slot of your motherboad? ~ x4 speed I know but you may have a dud pcie lane and it will do for testing purposes.
  • are you able to test the gpu and or psu in another machine?

Ok to be more clear I have decided that it is the power supply and NOT the graphics card. The psu is giving out lower voltages than normal and causing the pc to shut down if a device requires more voltage than is being given out. It is in no way the graphics card which doesn't ever go above 60c and I am using siw to check the temps thanks for all the help guys

just out of interest how low?

whoa, yep a powered paper weight for sure.
