Computer was working okay when I shut down, but when I rebooted the next day I got no video. I changed monitors, installed a working PCI graphics card, replaced RAM, removed battery (to reset BIOS) . . . but nothing helped. I've lost onboard video in other computers but was able to install a PCI card to get it back. I have some experience with general computer repair but not with mobo problems. I assume my mobo may be bad, but how do I know for sure? And why did it go so fast?|||If your computer is not working properly when it is switched on, it could be a problem with device drivers, hardware or software.
Detailed instructions at http://tinyurl.com/yd34oj|||Its usually visually undetectable when a motherboard goes bad. The only thing you may find to give clues that the board is bad are blown or bluged capactiors. These are the little electrical components that look like tiny soda cans. When they are good and functional the tops will look very flat, but if they are bad, they will be bulged and possibly leaking a fluid out of the top. If you see this anywhere on the board, then it needs to be replaced. But with all you have replaced, I would bet it is bad even if you don't see any bad capactiors. Besides, running a 466MHz celeron indicates that you are due for an upgrade anyway. It may be for the best. Not trying to be personal or rude, but this processor isn't sufficient for most of today's computing needs.|||all thats happened is you video drivers have gotten corrupted
just reinstall them
its not a big deal|||try starting in SAFE mode if the machine will come up in that then try to re-installing the video drivers..if not again try your add in PCI card but goto the bios and tell it to use the card and not the onboard see if that helps......and does it go thru post ?? if not you may just have a bad motherboard|||You can often diagnose any problem at the motherboard level by interpreting the number & types of beeps the PC generates at bootup.
Please follow this link for details (and make sure your PC speaker ...the internal one...is connected properly):

As to repairing MOBO. MOST are multilayer, and considered NOT repairable except by the manufacturer. (They usually just replace them unless it is a bad chip!; and it takes test equipment to find the bad part.)
If the MOBO, or system, is still in warranty, contact the manufacturer. (They will want you to return it for repair.)
