I updated my BIOS and now my PC has no post diagnostics. I have tried seemingly everything to no avail.

UPDATE: Took it into a repair shop, they got it back in a day. Said they took out all drives, flashed a new BIOS to a USB drive and turned the PC on. After a while, it detected the BIOS wasn't working, and asked to update BIOS using the USB drive.

As my title claims, I updated my BIOS on my PC this afternoon on a flash drive. After it reached 100% it restarted, but nothing happened on my monitors (they kept reading: "Entering Power Saving Mode" and "No Signal".) I should mention that for the past 2 days I had been mining on and off for ~12 hours a day, and overclocked, but would set the settings default when I came back and would always restart my PC. Also, when playing Player Unknown's Battle Grounds I would get 1 of 2 errors every 3 or 4 rounds:

1.) My monitor would go a solid color, often the most common color being displayed at the time. (i.e if I where to have a picture of a ocean pulled up, the monitor would go blue. I could still hear the in-game sounds, but not my friends in discord

2.) The blue screen of death, which said "VIDEO_TDR_FAILURE (nvlddmkm.sys)"

I have attempted the following:

• Taking out the CMOS battery for 10 minutes and touching a small screw driver to the two places the battery touches.

• Touching the 3-4 pins under JBAT1 with a small screw driver.

• Only using 1 stick of RAM in different slots.

• Using my other stick of RAM in different slots.

• Putting my GPU in a different PCI-E x16 Slot.

• Taking out my GPU and trying to use my integrated graphics on CPU.


This is my current PC part list: https://pcpartpicker.com/list/VT2QGf

Is it time for a new mobo? Can I somehow get this back? Is the BIOS stored on a chip that I can replace?

EDIT: So I did some more research and found that you can buy BIOS chips. Would this fix my issue?

So can you currently run your computer or not? If you take out the graphics card and run the on-board graphics, do you have similar issues?

In my opinion, it's your graphics card. I recommend you uninstall it and download it from the manufacturers website. You can find it HERE.

Make sure it's the right version and choose the right OS. See how it works. If it works fine, great! If not, update, simply upgrade it.

Hope it helps.

Cheers :)

I mean I can kinda run my PC. The lights turn on and fans start spinning, but monitors show no sign (I can't interact with the BIOS/OS what-so-ever.) I've tried uninstalling and re-installing the GPU driver a few times due to the blue screens and issues with PUBG, but it didn't make a noticeable change if any. Probably gonna see if the BIOS chip is the issue. Planning on ordering one tomorrow

The issue persists if you remove the graphics card and attach the display cable to the mobo??
