[Solved] Bios flash broke gtx 470?

post #1 of 5
Thread Starter 
After having a modified bios on my EVGA gtx 470 for a few months I decided that I wanted to flash a stock bios back on so that the clocks would decrease at idle again. I used nVflash to put on an EVGA 470 SC bios. After I rebooted the system, there was artifacts (a bunch of red lines) on the screen that appeared after POST.

I was able to enter windows and do a clean install of drivers and reboot, but still get the artifacts after the POST screen.

I then downloaded 2 different stock EVGA 470 bios's from the techpowerup archive and flashed them on to the card (seperately, of course), but still get artifacts after POST.

The commands I used were:

nvflash -r
nvflash --protectoff
nvflash -4 -5 -6 .rom
nvflash --protecton

Did anyone else ever encounter this? Any thoughts?

note: at windows login the monitor receives no signal and powers off, only under safemode can I even boot into windows.

Sounds like a dying card. Artifacts are usually caused by hairline fractures in the GPU's solder (used to 'weld' components to a board) and is not usually a problem with the bios. I would recommend reading this article and related ones:

http://www.addictivetips.com/hardware/fix-your-graphics-card-by-baking-in-oven/

Have you got a seperate gpu you could use to boot into windows, alongside your 470? Any will do, even if it is like a million years old. Does your motherboard have an integrated gpu? If you do then boot up using the different gpu and try flashing the BIOS whilst in windows.

Doubt it is solder related. It happened as a result of the bios flash for sure. There was nothing ever wrong with the card for the 2+ years I owned it, up to a few seconds before the flash. When I run in safe mode (without the drivers) the card runs fine.

I am currently using a 560 Ti; ruling out driver corruption and windows corruption.

I will continue to mess with the 470 on another PC for now and report back if I find a solution.

Fixed it. Went to an older PC I had, where I saved the original bios from my card. Flashed the original bios on to it and it worked fine.
