Flashing Video BIOS

[bennylava]

Thinking about tweaking the video BIOS lately, and I know BIOS flash can always be a risk. I am trying to understand the risk.

Under what circumstances would a BIOS flash fail? I know it's probably going to fail if you unplugged the power cable during the flash, but what if everything was compatible, the correct software was used, etc. Basically what I am asking is if it's possible for a BIOS flash to "spontaneously" fail without the user doing anything wrong? I am trying to fix a fan issue that is somewhat annoying but nothing I can't live with, so I will probably avoid flashing unless it's really safe, especially since I will probably flash multiple times if the issue isn't solved. Thanks.

a lot of bios flash failures today are from the motherboard vendors writing bad windows updaters. you should never update a motherobard in windows...a lot of backgroung programs like anti virus can stop a flash update and brick a mb. always use the bios updater in the bios or a dos boot disk. (that why asus newer mb use a usb flashback tool now).
