Power outage while both PC on.

[BruceUSA]

Power outage while both my PC was on. Both system has Eva supernova 1300w pus. House power was restored and one of the system failed to restart. When I try to restart I see the system cycling thru some code show on the motherboard led. The last code is seen is 4F then it's just keep rebooting with no code. I thought perhaps the pus was fried. So I got a spare brand new 750w psu. Installed and got the same thing. Maybe the motherboard fried? I have a brand new motherboard that I bought it years ago have it repaired as spare part while I bought a 2nd one.. It's a X399 AMD 16 cores threadripper. I am thinking install the motherboard. I have remove the cmos battery but the same. What do you guys think the cause?

Does your mobo have a 2nd BIOS? If so, try to boot from it. If not, try flashing the BIOS using the BIOS flashback feature is my suggestion.

No luck. I attach a couple of pics, you can see what I am doing. Copy & paste X399AG7.F3j into a USB stick. Plug it in to the motherborad dedicated white USB Bios Port. Restart the PC the USB stick light up and showing a few blinking light then stop, at the same time I also repeatedly pressing the delete key trying to enter the bio page. The motherboard LED cycling thru and then last code is 4F then disappear. Then the PC just trying to reboot. Do you think the motherboard is fried? I am going to replace the motherboard tonight.

Follow the instructions in your manual for using BIOS Flashback. Just make sure you're doing it right.

It's possible the mobo is bad, sure.

OK, a couple of things with BIOS flashback. The stick has to be formatted FAT32 and the BIOS file renamed to gigabyte.bin or similar. I don't know for sure but your manual should tell you

Page 6 here tells you the specifics https://download.gigabyte.com/FileL...atures.pdf?v=ba3ea59bd379098bb4bcb388e9e18452

Johan45 and Earthdog. Thank you so much. After rename it to GIGABYTE.bin and try it. The usb stick continue flashing for a minute or so. I feel relieve because it is doing the magic to correct the corrupted bios. After the usb stick light is disappear. I remove the usb stick and restart the system and I am able to enter the bios. But windows needs repair. I am working to restore windows backup.

 

[Johan45]

Glad it's working out for ya!

 

[BruceUSA]

I am able to enter the bios but I still not able to restore windows. I insert a windows repaired disk into the DVD drive and set the DVD drive as boot priority in the bios then restart the PC. I see windows sign on the monitor and then get a message needs repair but why it is stop continue on. It message got stuck and freeze. I also try to install fresh windows. After a few try. I will message like diagnostic windows or just a solid blue screen. That possibly the OS drive is dead?
Attach a few pics.

When the BIOS was restored, it went to default. Were there any settings you made in BIOS for your drives or the CSM settings

Johan45. I don't remember exactly what version bios was on the motherboard. But I downloaded the bios that support NVMe raid support. I think I might previously using the original default bios. Here a question. Can I flash the bios back to the default one. I am thinking give that a try. the repair disk may contain the original older bios. Please advise me what to do. Thank you.

 

[EarthDog]

Are you drives in RAID?

 

[BruceUSA]

Nope. Just a single 1TB Samsung 980 NVMe M2. Can I reflash the bios to the older version?

 

[Johan45]

Using the original BIOS isn't going to help. Go to your BIOS and make sure that NVMe drive is showing up

Ok today I swap out the motherboard. Power up the system and press del to boot into the bios fine. Then set boot priority to DVD drive as I have the windows disk in the drive. Save & exit. The system restart. The monitor showing press any key to boot from cd or dvd...... Press enter the monitor show windows logo and stay there. The motherboard led show AE. I don't know what that is. Everything stop at that point. What is causing this AE. Windows won't proceed to install? Any one knows?

Ps. Format and clean the OS drive before I try to install fresh windows 10.

Dvd? Try making a usb install disk from the MS website. Look up windows 10 installation media.

Also, Johan asked a great question you haven't answered... does the drive show up in the bios??

I have tried usb stick and for what ever reason I got a blue screen with code 61 . Of course I set boot priority to the USB stick before restart. I had successfully used this very same usb stick to installed windows before but not this time.
Please see attached pic. What can I do to fix the AE. Legacy boot event.

 

[EarthDog]

Check post 10 again. Make sure legacy boot is enabled?

 

[BruceUSA]

I don't see anything about legacy boot. I am snap pics. You can see there is no legacy boot I can see

 

[EarthDog]

STORAGE BOOT OPTION CONTROL is set to "legacy only". Is there a uefi or both option there? What about windows 10 features? It's set to other
