Hi; this is my build: Asus X370 Prime Pro Ryzen 7 1700 Corsair CX750M 2x8GB G.Skill 3000Mhz Cl10 Samsung 960 Evo 256GB EVGA GTX 970

I built this in september; tried some OCing with the CPU, but that didn't help much with the stock cooler (got to 3.7ghz max). Guess I didn't win the sillicon lottery after all.

This is important: I found an OC sweetspot for my RAM (I got it to 3200mhz Cl15 1.4V, I think; can't remember it correctly) months ago.

I bought a Deepcool Assassin II with Am4 brackets. Installed it yesterday and went straight to overclocking. Was able to get to 3.9Ghz 1.41V (my chip sucks, I know). Then, I went straight to overclocking my ram, back to my sweetspot previously mentioned. When I booted up, it was stuck in the post screen, so I turned everything off and on again. BAM. No post. No beeps (yes, I do have a mobo speaker connected, and it was working perfectly).

What are the odds I fried something? Maybe my mobo, or my CPU? I'm pretty sure the RAMs are intact. I tried using only one of them (tried that for both of them) in all slots. Also tried with a spare DDR4 ram I have here (which I already tested before, and it was working in this exact configuration).

I tried resetting the CMOS by taking out the battery many times. Last time I left it out for 1h30. Tried resetting through the jumper too.

Nothing works. Since it can't even beep, I assume that, if the mobo and the CPU are physically ok, then the BIOS must be corrupted, but if even the CMOS reset couldn't restore it to default, what should I do?

I updated the bios to the latest version exactly one day before all that. The system was working perfectly fine before that, too.

The system turns on, fans spin, bright red leds from my case, but nothing on the screen. No response from the Numlock/capslock/scrolllock of my keyboard either. This happens EVEN WITHOUT a stick of RAM plugged in.

What should I do? I'm kinda hopeless here. The only hope I have now is to leave the CMOS battery out for more than 10 hours (I read about a guy having a similar issue that did that and it worked for him). Do I need an external flasher for a fresh BIOS flash?

The motherboard doesn't even have a memOK button, or a Q-CODE display, or, goddamnit, not even red leds indicating CPU/RAM/VGA/Boot failure in it.

Help.

Actually you don't have to pull the cmos battery out all you need to do is reset the cmos via reset jumper un- plug your pc before doing this you can also disconnect your hard rives and gpu and ram then re start your pc then shut it down.
