Long story short, recently my motherboard is fried and I need a cheap emergency subtitute. Then I bought ASUS m5a78l-m le.

Eeverything nice and works fine for at least 2 weeks. Then suddenly out of nowhere I got CPU over voltage warning on boot screen.

I've look up in this site and I found
some solutions. Here is the things I've tried
- turning off the "cool'n quiet" feature
- change the "cpu over voltage" from auto to 1.30000 (I don't know what this means)
- make sure it's not a voltage spikes (is that how we called it?) From my old power supply
- using a Jumper pin and reset everything (even though I don't change anything)

And so far the things that works is only the jumper pin. But I have to do it afain for like the next week or so because the CPU over voltage error popped up again.

Oh one more thing. I've checked the Hardware monitor and the VCORE voltage is around 840 V. And it's red (again, Idk if this info helps)

I personaly think that the problem is in the motherboard, but you're the expert so I'm open to solutions

My spec are
Cpu : Amd fx 8350
MB : Asus m5a78l-m le
Vga : rx 480
PSU : enlight 600 watt

you are running a cpu that is too power hungry for that mobo you got

you must reduce its voltage and speed to something the crappy mobo can handle

840V? I'm surprised that the CPU is still alive if that's the actual voltage. I have a feeling it's a bad reading cause no PC would run with 840V, and I don't think there's a PSU on the planet that can output 840V.

Go into BIOS and set CPU voltage to 1.3 or something NOT 840, or anywhere close to any of those numbers. A quick google search of your motherboard and an overclocking guide will tell you how to set core voltage.

The big problem here is that you bought a motherboard that does not officially support 125W CPUs. You've been stressing it horribly for the last two weeks and now you're running into issues. You're likely going to need to underclock the CPU, reducing the voltage in ticks to the point that it's stable.

If you keep giving it more voltage, you have a very good shot at frying this motherboard too.

Project much? Nobody called you stupid. But for any PC problem, one needs to understand what the problem is in the first place before one can start to fix it.

Best of luck to you, I hope you fix your problem.
