Hi. First of all, I apologize my poor english. I am not good at English.

 

I have Radeon PRO DUO. It's great VGA, I think.

But after Cold boot, My monitor has no signal and I can't see bios logo.(only black screen)

After one or two power on, off, I can get the signal. Sometimes, the VGA fan spin on full speed with no signal.

Plus, sometimes, Screen stays black after waking computer from sleep mode.

 

I inspected My PSU and mother board and I turned off the igfx device on bios. but it can't help me.

I will take this vga to RMA, next week. But before RMA, I want to know why this happen.

 

My system is below

 

CPU : i7-4790k

M/B : Gigabyte Z97X-UD3H Durable

RAM : 24GB

PSU : superflower sf-1000f14mg

CASE : thermaltech CORE X9

OS : Windows 7 64bit sp1
