It's the BIOS right?

[Michael]

So i was overclocking my CPU, trying to get to a setting i had previously had (200x12.5), and i set it to 180x12, or something like that. Usually when an OC fails, the computer won't beep when i turn it on, and screen will stay idle, so i turn it off and on and it will tell me, and i can set it right. However, this time, i got no beep, and couldn't set it right again. I tried clearing the BIOS, removing the battery, waiting then trying again, over and over.

Nothing worked. I have tried the CPU, RAM and graphics card in another pc and all work fine... I'm guessing the BIOS is corrupt?... Oh, when i removed the CPU from the board, i got the audio warning through my speakers about no CPU installed, so the motherboard is working as far as i can tell.

The motherboard is an Asus A7N8X Deluxe (nForce2)

Well if it is one of the early A7N8Xes then yes, very likely to be BIOS corruption. Happened to 2 of my boards. The only cure is to get someone to hotflash it for you or RMA it.
Do you have the necessary tools to remove the BIOS and post it to someone?

It's not a borked BIOS matey, if she tells you there's no CPU. I had the exact same problem with the A7N8X-E Deluxe version of the board. I can only suggest checking everything at the moment to see what you can narrow it down to.

You say you had it to 200x12.5 before? Why did you then change it to 180x12? What changes have you made recently? Have you moved the heatsink (that was actually my problem, the HS wasn't on properly)? Have you taken EVERYTHING off the mobo and tried connecting it to the speakers/headphones to see if she says anything? Check all connections, add everything one at a time to see if it fails to POST and see if you can narrow down the problem.

I had the exact same problem a couple of weeks ago..... and as soon as I remember what I did to cure it, i'll make sure your the first to know......

Meanwhile, try, cycling the power in the PSU unplug the mains cable for around 30 seconds then plug it back in. Make sure when you reset the CMOS, leave it in the enabled position for a good few seconds, even try turning the computer on with it in the enabled position.
