Wow, this is like the 3rd post I have seen in as many days where people are trying to flash a new BIOS revison and ending up with a dead board.
The sad fact is they were all brand new boards, and did not need a BIOS update in the first place.
Here is this guy, spent money and time to put together a new system. Maybe read some posts, some stickys, ask some opinions. Got all the goodies together, and many people say the first thing you should do is update your BIOS.
This is just not the best advice! Unless you are having a problem, and the new BIOS update is specifically written to fix your problem, there is no reason to update it.
And let me repeat that again in a slightly different way. If you are having a problem with your PC, and the new BIOS revision was not specifically written to fix the EXACT problem you are having, updating your BIOS will not help you in anyway shape or form.
Updating your BIOS is a simple 10 second task.
Messing up during an update and ending up with a dead board is also fairly simple, as a few people lately have unfortunately found out the hard way!
The real secret is if you are not 100% absolutely positive that during the flash everything went "perfect", I mean 100% dead nut positive perfect.
DO NOT REBOOT. Re-flash it again and make sure!!
Once you reboot, if it's not right, it's all over. Dead board never to boot again until you obtain a new BIOS chip.
