I've just built this rig and I've been experiencing problems and I can't quite seem to find a way to fix this.

When I play any game for a period of time my PC freezes and unresponsive followed with noise emitting from the speakers.

My Specs are

Motherboard: MSI 970 Gaming
CPU: AMD FX9590 (Not overclocked) + Watercooler Corsair H100
RAM: x2 8gb of Kingston HyperX Fury RAM
GPU: x2 R9 270x Sapphire 4GB (Crossfire Enabled) Not oc
PSU: Corsair 80 PLUS Bronze 850W
SSD: Kingston HyperX 3K 250gb
HD: Western Digital Green 2TB Hard Drive
OS: Windows 8.1 Pro 64bit

I've checked my temperatures with various software including, MSI Afterburner, CPUID HWMonitor and another that I can't quite remember, however all after monitoring the temperatures of the CPU and GPUs while I played The Sims 4 (Yeah such a demanding game) the results showed no overheating and the highest temperature for my GPU was around 70c and 50c for my CPU.

I've also checked the voltages and they seem fine. I've read that I should try and increase the voltage of RAM from 1.5 to 1.5.5 however I don't know if that will fix it.

I've done a memory test and the results for that came back clear with no problems found.

If I have to take a guess. PSU, Corsair Bronze 850W is not a very good PSU. I don't understand, if you need so much Wattage, why go for the low quality?. It could be that, or it could be the video cards go unstable, which can happen to healthy video cards on cross-fire. If it happens very often though, something is wrong. Your video cards on crossfire eat a lot of power, being plugged to a mediocre PSU they don't get quality power and they crash.

Check your crossfire connector, make sure they're plug correctly. I had a problem similar to this once, and it was just my crossfire connector wasn't plugged all the way in.

Yeah well... bronze is not good... bronze is good for builds that require less power, but with crossfire I would go with a good EVGA or Corsair gold certified. Did replacing the bridge helped?

I'm testing it now, it might take an hour or so to see. I will message if anything develops.

Try without cross-fire, unplug one video card and test it... then try the other video card... this way you will be able to tell if one of the video cards is defective. If they both fail then you know it is either CPU or PSU. Can you stress run the CPU? I doubt it is the CPU though.

So far it's been roughly two hours or so and there is no problems with one GPU taken out, I will keep the test active for another 30 mins and replace the GPU and test it for 2 hours and 30 mins.

Ok that's good. If the other GPU fails, you know the GPU is defective. If that's the case, you can send it to Sapphire for RMA. If nothing happens the problem is most likely the PSU, I would get a new one. If you want to do even further testing there's a few tools you can use to monitor your PSU.

Thermaltake PSU tester:

http://www.amazon.com/Thermaltake-Automated-Supply-Oversized-Supplies/dp/B005F778JO/ref=sr_1_2?ie=UTF8&qid=1432732375&sr=8-2&keywords=PSU+tester

You can test your PSU for instabilities with this device, it is fully automated so it is very easy to use. It will tell you if your PSU is defective, being unstable or giving out abnormal power supply.

Kill-A-Watt electricity usage monitor:

http://www.amazon.com/P3-P4400-Electricity-Usage-Monitor/dp/B00009MDBU/ref=sr_1_1?ie=UTF8&qid=1432732461&sr=8-1&keywords=Kill-A-watt

This will tell you how much power your computer is consuming in real time, it will let you know if you are getting close to your PSU max wattage. If you get more than 600 watts when stressing the GPUs, or close to 600 it is likely your PSU could be holding you back not being able to provide enough power in a stable manner, since it is not a high quality PSU.

You should always get a high-quality PSU for any computer that requires more than 500 watts on high load.

Should I get a Corsair CS850M 80 Plus Gold or EVGA Super Nova 850w Gold? I can't exceed £90

It says on Amazon it will take a week to dispatch so I will have to update in a weeks time or so depending on when I get the new PSU, I'm still testing the GPU and have around one hour left of testing.

Okay it appears that the second GPU is defective as the PC froze moments after I sent my last comment.

Is it still under warranty? send it back to the manufacturer and explain them the test your performed on it, so they can replicate it and don't send you back the same video card.

I bought it on Amazon and going to send it back for a refund and I'll buy it again >.<

I'm doing another test on the first card to make sure.

Okay the first GPU has also crashed the PC, I should note that I placed the first card where the second card was.

Okay I'm going to buy a brand new PSU, a EVGA SuperNova G2 850w Gold 80+

It will take a week to confirm this is a problem and I will try to update asap. Thanks guys.
