I'm waiting for you to stop crossposting, so someone can help you. This doesn't belong in sci.electronics.design. Try posting *only* to the alt.comp.periphs.mainboard.asus group, and then someone can walk through a test procedure..
The more you muck with this board, the more damage you are going to do. You don't have 5% of the knowledge or the tools to work on something this complex. Either get a new motherboard, or send this one back for repair. Expect to pay for repair, as you have likely voided the warranty by messing with it.
And please don't post this endless tale of woe to s.e.d. It's actually not appropriate.

My PC(900Mhz Athlon) was having trouble BECAUSE of a bad PC fan. It was loading the PS and causing reboots.And the fan was still turning at speed,not slow.
First check the CMOS battery. Most will run with a dead battery but it is a pain having to enter the settings every time you power it up.
What are the Power On Self Test codes telling you? The computer should beep the internal speaker one time if everything is working. More than once means you have a problem - the motherboard manual should tell you what the beeps are indicating is wrong. Research POST codes for the mobo you have if that's the case. The POST is there so you have some way to troubleshoot if the display or keyboard is having problems.
If it beeps once and fails to boot, but the screen comes up, use the start up disc, your master boot record must be damaged. The boot record is corrupt, missing or not where the BIOS expects to find it.
There's a DOS command for restoring the master boot record, RMBR, but it depends on your version of windows or what OS you are using. Research the problem if that's the case. Drive overlays, and added stuff like PCI hard drive controllers may require a non standard boot for everything to function properly. Plain vanilla computers are easier to fix.
Unlikely. You're the computer expert - certainly you didn't kill it.
Lightening and Tesla coils can write to the bios settings on my system, but they only change the date time, and maybe at worse, I'll have to re detect the hard drives. That last has only happened once.
Are you flashing the BIOS? That is asking for trouble with most motherboards. You said something about an Asus board in one post, they are supposed to be almost idiot proof with their flashing system.
The ONLY time one flashes a BIOS is to upgrade to allow it to handle some piece of added hardware or to eliminate a bug in the original flashing - Flashing the BIOS is a last resort no matter how good you are with computers. Last resort - means you have already spare BIOS in one hand or a back up computer and really, really, need it.
Best plan is don't flash - unless of course you bought an ASUS with the foolproof flashing and bad flash recovery.
Anything is possible
You were wearing your "summer shoes" again and shuffling across the carpet?
Wrong settings are common - they will make it look like the BIOS or MoBo is bad - but there's usually a choice somewhere in the BIOS setup that allows one to chose default settings - to bring it back to something that should work, then you just have to choose "detect hard drives" or enter the number of heads and cylinders from the HDD spec sheet manually.
The BIOS itself runs cool, it doesn't do much except start the computer and hold the settings, it doesn't use a lot of power - they have to run on batteries for back up. If the BIOS dies from heat, it would probably be due to another source of heat - a hard drive or processor is more likely to die of heat, it generates.

Maybe. But more changes may only exponentially complicate the problem. BIOS does not operate until it receives a signal from the power supply controller. The power supply 'system' (which is more than just a power supply) can be completely defective and still a light glows; fan spins. There is no way around numbers. There is no way around first confirming the power supply 'system' is functional. That is two minutes with a 3.5 digit multimeter - a tool so ubiquitous as to be sold even in Kmart (and Radio Shack, Lowes, Tru-value Hardware, Sear, Wal-Mart, Home Depot....)

Use numbers in that discussion AND post numbers here for further information (and to learn what those numbers say).
Never swap parts or change wires until a suspect has been identified. Two minutes with a meter will either accuse or exonerate the power supply 'system'. Only then are you ready to move on to other suspects. Doing it this way means you know what is good and what is definitively bad. Currently, everything remains unknown - the third state.
Get the meter. Use the procedure. Report back the numbers. Two minutes to uncomplicated a problem.
The answer is simple. The motherboard is dirty. Carefully place the board into a plastic tub half-filled with hydroflouric acid (5% solution) and allow it to soak for 24 hours. If you're really in a hurry, make it 50% solution. This will thoroughly clean the bios contacts and, well, everything else on the board with remarkable results. It also works wonders on you car windows.
ha, you didn't pull the memory ? you should at least do that to see if you get the memory error code beep ! if so, that would tell you that you have a bad chip.

as far as your CPU, i don't know, on my MB, i have a mini processor that's part of the MB resources and it channels the primitive speaker out to my shelf speakers. It will verbally tell me if there is no CPU. after all the post are done , then tells me it's booting from the operating system. You don't need the memory in for the very basic boot start that bios goes through when resetting the main CPU.. Most MB's have a wire called the PG (power good) that will shut the power supply off for various reasons.
You have to stop complaining and do some serious research .
