Boot problem Asus P5B deluxe (out of the blue)

[JohnnySG]

Hi,

I have a ASUS P5B Deluxe (3-4 years old mobo) which has been working good. My Intel E6600 (I believe that’s what it’s called) has been ran in stock settings all along.


The problem arose the other day when I was booting up my computer. I the received the following message during boot:


“CMOS settings wrong
Overclocking failed! Please enter setup to re-configure your system.
Press F1 to run setup
Press F2 to load default values and continue”


Issue 1: I don’t overclock.
Issue 2: I can’t press the buttons.
Issue 3: I can’t press anything else to enter the BIOS.


Suggestions for failure 1: My CPU fan is a big beast and if you shatter the computer case, it risks falling a bit out of position, thus resulting in cooling failure. I had a cleaner in my apartment between the last time the computer worked and now and she might have touched the case.
Suggestions for failure 2: The CMOS battery had a little brownish spot on it. Could it be “burned out” or just dead?


Attempt 1: I re-attached the CPU fan with the same result. I.e. suggestion for failure 1 is less likely.
Attempt 2: I removed and put the CMOS battery back, without any changes in results.


What can I do?



Would very much appreciate any help!

3-4 years? Check the CMOS battery with a multimeter. It should be around 3v. Replacements are pretty cheap - Radio Shack has 'em for $3.

Yeah, replace CMOS battery before doing anything else.

OK guys, thanks for this tip. I'll replace it and come back!

Probably CMOS battery as others already suggested, otherwise you might want to reseat components CPU etc. What happens if you load and save default CMOS values in BIOS?

Hi guys, I replaced the CMOS battery, but with no luck. :-(

Cannot enter BIOS...

Using an old PS/2 keyboard saved me the headache. I guess it + the new batt did it!
