Last night I had a shortcut due to a bad storm and when I open my computer I saw the logo and directly go in my bios, I had touch nothing to the bios and press save and restart. Bam, black screen with a white bar on my screen, freeze to death. Red boot light was on. After I restart my computer I had only black screen with nothing left but a cpu red light. I retried one last time and both cpu and ram was red. Does that mean my mobo is dead basicly? I tried jumper to reset my cmos, Tried to shut down psu and re open it. all the fans in my pc are running. Don't know what to do left. Tried to look on internet to buy a new mobo : Sabertooth 990fx R2.0 but they are out of stock and people sell them for 800$ for new. I would love to buy a new cheap mobo to see if my fx-8350 and my 16Gb of corsair vangence 1866MHz are alive. I think even my SSD 840 EVO is maybe dead. Maybe it is the psu but last night I was playing video game with the pc base on luck. Because I had shut down the psu and hold the power buton for 30 seconde and re open the psu and press again the power buton to reset the bios and it worked. But today when I tried this trick it didn't work like last time.

Hello,

Steps you should take in order to troubleshoot the problem:

1. Borrow from someone 100% working PSU, attach it to your rig and see if it's working.
2. Measure voltage on CMOS battery that is powering BIOS if bellow 3V replace it.
3. Download stable version of BIOS from manufacturer website and flash it via USB. (carefully follow instruction manual)

Your PSU should have taken the blow and saved rest of the rig. Follow this 3 steps, if nothing helps then it's time for new configuration.
