CMOS or motherboard ?

By gill ·
I have a pc which doesn't start up at all. There is power but that is it. No BIOS information appears on the monitor and needless to say that there is no boot sequence to speak of.
I have checked the HDD settings and I have checked the memory. I also swapped processors on the off-chance that the processor might have burnt out but to no avail.
I have since found out that some individual cleared the BIOS memory.
Is there anyway of retrieving this information so that the machine can be recovered ?

CMOS or motherboard ?

by dmiles In reply to CMOS or motherboard ?

The info could be retrieved if you have the motherboard manual or a backup,if this is not possible then try looking for a mother manual from the following site www.motherboard.org

First,try booting the computer and press the key to enter SETUP,locate the line that says to Set Bios default and select save and exit.Any possibility of resetting configuration will depend on the jumper setting being placed back to the original position after clearing the BIOS

The other possibility is that if you can note all you hardware you may be able to enter Setup and manually set the configuration settings of the machine by following each configuration setting in the setupup panel.

I hope that you mean that someone cleared the BIOS settings, or CMOS memory. If so;

Check that the jumper to clear the CMOS memory is not still in the clear position, and that the battery is not weak.

Otherwise, double check that the memory isconfigured properly and seated properly in the sockets.

If someone actually cleared the BIOS there is little you can do to recover the motherboard.
If you know the make and model of the motherboard, you may be able to purchase a new BIOS IC fromthem.

There is a 3rd party BIOS firm that you can find a link to from the Phoenix bios page that may be able to provide you a new BIOS chip for around $100.
However, they need the BIOS ID for the motherboard.

The motherboard is almost certainly bad. Try this, disconnect everything (including floppy, mouse, keyboard, all cards, panel LED's) from the motherboard except for power, video and memory then turn it on. If you still have a blank screen, pull the video card and try a different one in a different slot. Still no video, replace the memory chips. Still no video, move the memory chips to different slots. Still no video, remove the memory chips and video card and make sure the speaker connector alone is plugged in. The motherboard, by itself, should give you a series of beeps whenever there is no video or memory installed. If you hear no beeps, either the PC speaker or the motherboard is bad. I'd bet on the motherboard.
