Two dead motherboards

[Reem1k]

So basically I bought a new motherboard because all signs showed to the bios chip being damaged. I sent the new one to guarantee repair just in case. The other one is the same model and it broke suddenly while watching a youtube video.

 

I'm guessing the first time might've been due to a power outage, but someone could've returned the second one due to the same problem, because I didn't see any stickers on the board that usually prevent you from opening it right away.

 

If you have any suggestions, please reply right away so I can try it out that way.

 

I bought a new motherboard (msi B250M PRO-VD) and got the ME FW f ound abnormal message. I want to update bios, but mflash and the bios itself doesnt recognize any usb at all.

 

Edit:

Problems: USB devices not working at all, HDD showing up as 0.0GB

What I've tried so far:

 

1. I've tried out ALL usb ports in the front and on thr motherboard. No luck.

 

2. I've tried using a PS/2 keyboard. Works in bios, but I can't progress because I want to install windows and USB doesn't work.

 

3. I've tried to go to bios with one ram stick, everything else apart from the cpu removed. No luck.

 

4. Taking out the CMOS battery

 

5. Tried another power supply (it's from 2008 though so it might not work correctly.)

 

Specs:

CPU: Intel Pentium g4560 with stock cooler

MOBO: MSI B250M PR O-VD

GPU: ASUS GTX 1050 2GB

HDD: 750gb (seagate?)

RAM: 2x4GB Adata and Crucial

You should wait for the first one to be repaired. If is still doesn’t work you need to get a new mobo again

Could be a bent pin on a usb device? Check all your devices are not killing the motherboards.

Or the 5v rail on the Powersupply.
