New GPU Crashing

[tylerjones]

I just upgraded my Gaming PC by adding more memory and an ASUS Radeon RX580 GPU. Before the upgrade my CPU's built in GPU was all I had for graphics. Now that my PC has been upgraded however, once in a game or while launching my PC will reboot itself. I've tried uninstalling all drivers and reinstalling and still gotten no results. Pretty sure all my software is up to date now. If anyone can help me I'd really appreciate it.

Specs:
CPU:AMD A10-7850K Radeon R7
MB:MSI A88XM-E45
RAM:16Gb 4x8 DDR3-1866 Gskill RipjawsX
GPU:ASUS DUAL RADEON RX850 (New)
OS:Windows 10 64bit

What power supply?

RX580 uses 185W on its own. If you don't have a reasonably decent 500W power supply that could easily explain your problems.

The CPU may also be over stressed now and overheating. When it was running just the APU it wasn't going to get a huge frame rate. Now that it can the CPU has a lot more to do to keep the GPU fed with data. You might try turning v-sync on to cap the maximum frame rate.

I have an Enermax Revolution-Xt II ERX750AWT 750W 80Plus Gold Certified Power Supply.

Tried enabling V-Sync, but it still crashed after a minute.

New question:If my CPU isn't good enough for my GPU is their a setting or something I can do to fix this?

If the GPU is causing the stress, the solution is to reduce settings. V-sync would usually do it so the card isn't rendering as many frames as possible. (unless you have a 144hz monitor or something, then v-sync doesn't do much)

The key here is monitoring. You want to see what the system is doing right before it crashes. Something like Hardware Info 64 (HWInfo64) or Hardware Monitor will let you keep an eye on things.

The CPU or GPU could be overheating. If it is the CPU, you just need a better CPU cooler. It is possible you got a bad GPU and you should start the RMA process to get a replacement. (If you have access to another computer, test the RX580 there)
