Hi All,
Lately I've been having some trouble with my system based on a Gigabyte GA-870A-UD3 motherboard (Rev 3.0).
Sometimes when I push the power button the computer doesn't start. No fans, no beeps, etc. The only thing that happens is that the PSU (Corsair AX850) starts making a faint buzzing sound.
What I then need to do is switch off the PSU itself using the button on the back. And then after switching it back on, try turning the PC on again. Sometimes I have to do this several times.
Today after trying this unsuccessfully a few times, I eventually unplugged the 2 power cables (ATX and ATX_12V) from the motherboard and then plugged them back in. Then the PC was able to start successfully.
I've got a Corsair AX850 in my other (Intel-based) desktop PC as well, which has never given me any trouble, so I'm inclined to think the motherboard is at fault rather than the PSU.
The problematic PC is using a Radeon 6450 and I read a forum thread elsewhere where someone solved the problem by switching to an nVidia card. Do you think it's likely that the GPU could be the cause, or is it more likely the motherboard?
Does anyone have any suggestions?
