Phantom GPU Problem

[Chaos_Theory01]

Around a month ago, I upgraded my graphics card from a RX 460 to a RX 580.

It has been working fine until today, when playing GTAV, my PC goes into sleep mode, and wouldn't reboot.

Shut down machine, and checked all connections to be OK, but whenever i tried to reboot, no fans or anything,

just a brief flash on the GPU and water cooler LED's

Replaced 580 with old 460 and system is working fine now

Just wondering what may have caused the problem, and how to get 580 back into rig.

 

System specs

Windows 10 64-bit

CPU: AMD FX-8350

GPU: XFX RX 580 GTS XXX Edition

RAM: 4x 4 GB Kingston HyperX DDR3 1600Mhz

BOARD: MSI 970 Gaming

PSU: EVGA 650 GQ

did you uninstall/DDU the drivers from the 460 and update the drivers for the 580? That could be your issue. 

Its also possible that you received a faulty 580

Just uninstalled the 460 drivers and reinstalled the 580.

Still no fans or anything, just brief flash of GPU and Watercooler LED's

Going to contact the manufacturer and see if they have any idea.
