Hello everyone, this is my first post here, and if I'm writing this is because I ran out of options with mi issue.
So, I was having problems bringing back my PC after hibernation. In fact, I had problems even putting it to hibernation. The screen will shut down but fans will keep running. Usually, after a hard reset everything will go back to normal. However, a couple of days ago, the system refused to launch anymore. PC is running, because lights are on and fans are running. However, it won't post. The MB speaker also doesn't make any sound anymore. I swapped EVERYTHING: CPU, GPU, RAM, Power Supply, SDDs and HDDs... and nothing. I tried everything written in this posts, because the authors seemed to had similar problems to my own:

Currently, the only explanation I have left is that MB is dead. I have a theory: weeks ago, I bought an audio interface to plug in external speakers. The AU is powered via USB, but the speakers get their power from the wall. Is it possible that, leaving the speakers on during computer's power-off and power-on, the motherboard has been fried?
Thank you very much, here are the specs of my PC:
MB: MSI Bazooka B350M
CPU: AMD Ryzen 3700X
GPU: Asus Stryx GTX 970 OC

SSD: Patriot M.2 NVMe 512GB
HDD: Western Digital Blue 2TB 7200RPM
PSU: Gigabyte Technology P650B 650W 80+ Bronze

Desktop won't boot after hibernation
I have googled around, but can't seem to find similar issues, so I am going to ask here. Some background information: My desktop is a few years old, but when I built it the components were all brand new and have worked quite well. Motherboard: Asus Z77 Sabertooth CPU: i7-3770k with Corsair...

No BIOS, no POST, but Power and Fans are on
Hey guys, been working on this the last two days. I have been working on recovering data from my SSD on a different computer, and since I had the case open to put it back, I decided I'd reapply the thermal paste on my processor/heatsink (CoolerMaster hyper 212+). Once I plugged everything in...
