GA-X99-SLI: Auto start after power supply

[kret007]

After turn on Power Supply (via switch on it) my computer start on it's own and won't do anything else, I mean OS (Windows 10 64bit) won't start. FBIOS_LED go first dim then bright and turn off (I don't know if it means anything).

What I tried and got up now:

• I tried to unplug front panel switches and it's that same, so it's not a fault of power switch
• I removed all peripherials but CPU and Power Supply and it's that same behaviour
• I disconnected Power Supply from motherboard and it didn't start, so i guess it's not PS fault

I don't know what BIOS (UEFI) version I got, but I didn't do anything with it, so I think it's stock.

Anyone can tell me if it looks like unresolvable Motherboard problem or any hint what I can do? I tought about CMOS reset or battery replace, but I would like to get other opinion before any mingling.

Reset the cmos just to see if it helps if it doesn't then you might have a corrupted bios and will need to get the back up bios going so it will overwrite the booting bios.

Here's what worked for mine:
1. Turn off machine.
2. Press and hold reset button.
3. Press power button while keeping reset button pressed for 10 secs then release.
4. Wait until the backup BIOS prompts and asks to install backup to main BIOS.
5. A window will pop-up stating that the main BIOS is corrupted and needs to re  flash, I hit "install"
6. After installing the bios, it will ask to boot or reboot, then will ask to load default or optimized settings in the BIOS.


After doing this post back with any problems, might be a good idea to update your bios.
