Loud pop, Smoke, motherboard smelled like burnt electronics, replaced cpu, and motherboard and still no display

[Tacomaco47]

I cannot get a get the display to work and im to my breaking point. It worked fine for about 4 months and my friend ran a overclock program while playing a game. Next thing you know there was a pop, a little smoke and the smell of burnt electronics. I have a Asus formula v motherboard, that i replaced with a asrock 990FX Extreme 9, and i also replaced my amd 9590 with a new one. I also have a corsair 850 Gold PSU that i swapped with a 700W PSU. Everything i change the fans still work, everything lights up, the fans on the graphics cards work, but still no display. There is no bios no beep, nothing. Please help.

could be the gpu then. do you have another one to test with?

I have 2 gtx 770's SLI, Ive unplugged one and removed the SLI bridge and still nothing.

The question is what was your friend overclocking when he smoked it (and can he replace it)? If he was messing with the GPU, and caused it to burn, chances are its done. If he was messing with CPU voltage, I would bet your motherboard is toast, if not the CPU AND motherboard.

Did you try the other one?

Did you not read the part where they replace the CPU and motherboard already?


Well really, that only leaves the other GPU if you didn't try that particular one and the RAM.

Yes, I did see the motherboard/cpu was replaced, except the system not working still doesn't mean the GPU is at fault. Especially if said "friend" was messing around with CPU stuff at the time. There are a lot of unknowns here. Maybe the new motherboard doesn't work with the CPU, or needs a bios update. Maybe the old PSU doesn't work. Hard to tell with the information given.

If you have a functional system, you could try replacing the GPU with your questionable 770 to see if that's the issue.

Could you test with onboard graphics?

As getochkn suggested, have you thought of RAM?

AMD 990FX based board's don't have built in video. That motheboard has supported the 9590 for all BIOS revisions.

That's my problem i have no clue whats going on.

Maybe your "friend" will let you "borrow" his GPU, its only fair.
