I have a Soya SY-7VCA mobo that hasn't been used for about 6 years. Upon bootup, I received a CMOS checksum error message, but was still able to load a copy of Windows 98SE that I had on floppy. After...


Probably your BIOS battery, replace that and setup you BIOS again and it should be fine. BIOS batteries look like little round watch batteries.

Any more questions just let me know.

Thanks

1 long 3 short unit shuts down


If not graphics card problem, you are looking at a motherboard error. Try removing the bios battery for 5 mins, replacing and resetting the cmos settings to default, if that works, I'd consider thinking about a new mobo sooner or later.

If this does not work, motherboard possibly failing

MCP61PM-HM mobo won't run long enough for os to boot


I'm assuming you didn't use the Cmos jumpers to reset the cmos and only replaced the battery?
Checked board to see if there are any capacitors bulging, leaking r blowing?
You don't say why you removed it in the 1st place? I'd remove it again and test it outside the casing, see if that solves the problem, then look inside the casing to see if there is anything that could be causing a short,
Other than that, you may have damaged a component on the board when you originally removed it

Low battery alert at start up. must always type


The only battery in a desktop PC is the CMOS battery. This is a 10c sized silver disc that is held in a plastic black clip on the Motherboard. It can be clipped out and easily replaced. they are 3.6v and somewhere like Radio Shack etc. will have them.

My ECS P4M800Pro-M board will not hold bios after shut-down.


Good day sir/ma'am, we have several old motherboard that acts like that and everytime we turn oon the PC, CMOS/BIOS previous settings were not saved. even new batteries did not solve the problem, We suspect its the CMOS/Bios chip itself is the culprit. We did replace the whole mobo with new ones and scrap the old ones.
My answer to your Q is maybe, until we try to update it. but the best is to replace the bios chip.

When I make changes in bios they won't save. F10 doesn't work


If you are also experiencing a problem saving the date and time in the BIOS, then you probably need to replace the CMOS battery. Also, chech to see if the CLEAR CMOS jumper on the mobo is set in the correct position.

Checksum error, pc clock returning at jan 1, 2004


flashing BIOS is not needed in your case. The only way to solve your issue is to make the mobo work. When working, thats the time you can use utilities to flash your BIOS.
For now, visit your CMOS Setup by pressing DEL or F2 at startup. Then choose LOAD SETUP Defaults.

Single Beep on boot... repeats after 2-3 seconds, no video


This is a tough one. On some system bioses one beep means a problem with the RAM. On most it means a succesful POST. Are you getting any video? Have you tried booting to a boot disk? Have you tried a new hard drive? Have you tried to clear the CMOS? Good Luck!

Firmware has detected cmos battery failure even after changing the battery


If you have basic knowledge with electronics or that you know the basic shapes of electronic parts, look for a busted electrolytic capacitor on your mobo...it may look bloated or discolored. It can be found near the coin battery. Ask for an expert electronic technician to replace it. If it is still under warranty, have your mobo replaced with a new one.
If your mobo has its circuitry doing fine, you will need to update your BIOS software. Have someone assist you on this especially those who are computer engineers.
