GPU runs fast then pc shuts down

[Venuez]

Hello, so I'm having an issue with my newly built custom pc. Here are specs:

AMD FX 6300
GIGABYTE 78LMT
4GB of RAM (not sure of brand)
WD 1TB 7200RPM harddrive
GIGABYTE RX 460 2GB OC
Bit Fenix Comrade Case

The RX 460 has a feature where you can control the fans, and at certain temperatures the fans spin either at 10% or 50% etc. I was just browsing and my GPU fans started spinning at 100% and it won't stop. After a 1 minute or so, my PC shuts down and restarts. I feel like this is a glitch with the Gigabyte Xtreme software but I'm not sure. Please help.

Out of curiosity, is this the board you have or is it a different model? Are you running on a 2x2Gb stick loadout? If so are they both of the same bran and of the same frequency? You forgot to include your PSU's make and model and the OS.

Have you made sure your motherboard BIOS is up to date? You may want to use DDU, uninstall your GPU drivers and then reinstall the latest Catalyst Drivers Suite. If the latest revision causes the issue, then drop down to the last known stable drivers. If you think it's the Gigabyte Xtreme software suite, then have you uninstalled it and ruled out the issue?
