Wanted to install a GTX 1080 in my wife’s machine last night, but I think I ended up frying the motherboard instead.
- Board: ASUS M4A89GTD Pro
- PSU: Corsair HX650W (it’s a pretty nice PSU, so I’m assuming it has some kind of protection against overloading?)
The machine was working with an HD5870. All I changed was the graphics card.
I Googled around and was pretty sure the board could take the 1080 without issue, but when I switched the machine on the first time it looked like it was stuck on the “Entering ASUS ExpressGate” screen.
Switched it off and back on and it won’t POST at all. Black screen, no lights on the keyboard. Sometimes the mouse will light up, but never the keyboard. I’ve tried another keyboard just in case. I’ve also tried plugging the keyboard and mouse into different USB ports which gives random results — sometimes the mouse turns on, sometimes it doesn’t.
I’ve removed the graphics card from the machine entirely to try and use the on-board graphics, but it still won’t POST.
I’ve tried resetting the BIOS, and have even tried removing the CMOS battery for 30 minutes. Still nothing, no POST, even with the graphics card removed.
Did I kill the motherboard, or is there a chance I somehow overloaded the power supply and that’s the problem?
