troubleshoot GPU Hard ShutDowns on my computer

[williamc142]

Hi people, I have an Asus ROG Strix Rx 480 8gb that makes my computer shutdown suddenly, sometimes it just turns into black screen and the fan speed just goes nuts, i've tried reseatting the PCI-e connector, testing with 3 different power supplies, and tested the card on different computer, it just hard shutdowns my computer, what might be the problem on this card, i've changed other gpu from my other computer (GTX 1660s) on my test bench and it just runs fine, is there any way to find out the problem on this Rx480?

 

sorry for bad english.

probably higher powerdraw than the gtx1660, check our PSU

I've tried it with 2 other 750w psu's, Enlight 750w 80+ white (didnt know the model), and one is brand new coolermaster mwe 750 80+ gold, i first thought it was a power supply problems, i've tested it on different computers (which has 500w PSU) but it still did the same problem i've encountered

 

edit:

Note i've Tested benchmarking my CPU, passed 3 passes on memtest86, all temps on CPU & GPU are normal (around 60-70 degree celsius) and when i benchmark my gpu it just turns off my pc, or just black screen and the fan speed goes crazy fast

Have you overclocked the GPU? 

 

If so return it to factory settings and see if that fixes it

Nope, im not overclocking the gpu

You might as well just replace the GPU with another one. Its obviously a total dud. Instead of getting another RX 480, get an RX 580 instead for your trouble and call it a day. The RX 480 is just about obsolete for today's games anyway.

i think this is a thermal issue, because the card heats up crazy fast, like it jumps from 50 degrees into 95 degrees within seconds, i changed the thermal paste and running the card at 100% fan speed, i think that's the only way i could do, but the temperature still rises slowly and hitting 90 degrees, i might consider getting a new card, but i wonder if i could revive this card.

Why bother trying to revive it? If thermal paste can't do it, then nothing can. You might as well just replace it. Another thing that would contribute to heat is a badly designed case. It matters a great deal when it comes to air flow, unless your system is water cooled. So you should take that into consideration too, and get a dust filter if you don't have one already.
