Asus CUV4X boot problem

[Aaron White]

My computer is a 750MHZ Pentium 3 with an Asus CUV4X motherboard. I
had it unplugged from everything for a day or so while moving things
around, and I plugged everything back in today. It had been working
fine, but now it stops in the BIOS after the memory test on the line
Award BIOS xxxxxx and does nothing. It doesn't respond to the
keyboard, so there's no way to change any settings in the BIOS; I have
verified that the keyboard works with another computer. It gives a
single short beep like normal which indicates there's no error
according to the motherboard's manual.

Does anyone have any pointers on what could be wrong? Nothing has
changed except the computer was unplugged for a short bit of time.

Open it up and make sure that everything is seated OK. Unplug each card ,
memory module and drive one by one and reinsert or reconnect them, making
sure that the connectors are clean as well. Make sure your PSU is set to
the right voltage. Take a look at the pins in your keyboard and mouse
plugs. Are they damaged? It's an older mobo. Make sure you have a good
CMOS battery. Make sure your CPU is properly installed as well.

First of all I have had a CUV4X and a CUV266, and both are good PIII
motherboards.

Couple things....

Your CMOS battery (small rechargable) could be dead. Try installing a new
one (a couple bucks) and make sure your computer is plugged into an always
live power source. If it is plugged into a surge bar, do not turn the switch
on the bar to off.

Sometimes moving things around can loosen components. An upgraded heavier
heat sink my be wiggled loose or worse it may be still attached to the
processor and can pull it off the socket.

Also a simple thing. Maybe mouse and keyboard plugs are reversed at the back
of the computer?

The battery used on the CUV4X series is NOT rechargable. It's a lithium
CR2032 3V battery. But that probably isn't the problem.

OK, I managed to lock up a similar MB. There is either a jumper or
solder points like a jumper should go there by the battery. You short
the jumber/solder points for about 30 seconds. This will clear the
CMOS and let you set it for factory defaults. Then turn on the computer
and you SHOULD be able to enter the BIOS setup. Notice I say SHOULD.
Is it overclocked? Asus is pretty good for overclockers but I
personally don't do it.
