Boot to CMOS and no further...CRAZY!!! NOT a normal "No boot device found".

Posted on 2006-05-08

I have a SOYO KT-400 Ultra Platinum Plus (silver colored board) that boots to CMOS but goes no further...never says "OS not found, please insert floppy" (or whatever that message says when no HDD or boot source is present). BUT it DOES say something like "Hardware problem, please see manufacturer". I removed ALL cards, reset CMOS (shorted reset pins and also removed batt. and shorted battery holder terminals), set CMOS (yes it let's me into setup) to basic no fail defaults, changed CPU, memory, known verified VID card (all verified components in another machine with same mobo). Tried with two HDDs, both with perfect installs of XP and BLANK formatted drive.

Very strange. Personally I think the board is bad. Different mobo with same components, same HDD etc. is fine - it's as if the moment it tries to do anything past exiting either CMOS setup menu or just a regular boot without entering CMOS it just craps out. I have 5 Soyo boards all in homebuilt PCs so I pretty much know what I'm doing (does 4 years Sys Admin of a Novell network consisting off over a hundred PCs and 55 Mac's count as experiance, too?).   :)

Help! NEVER seen this nor have any colleagues (nor has least the two techs I spoke to).

    Hi jamroc2000,

    If you have replaced all components with known working components on another board, it should be a simple fact that the board is dead

    I would send it back to Soyo and get them to make it work, get a replacement, or a refund

    Hope that helps,

    try taking the mobo from the pc that's not working & try putting in into one of the other computers (keep only cpu, ram, video, & hard drive.  if it can boot in another box fine then it could be the pwr supply in the old box.

    i say this because i ran into this problem on my son's soyo board & i did everything you had so far.  when the soyo tech had me remove the board from the box, leaving it lay flat on cardboard, the pc booted fine.  however, if i stood the box up the system (leaving mobo where it was) the system would restart back to the bios screen & not detected my hard drive.

    anyway worth a shot.

    Have not tried that. Is there any way to confirm BIOS is bad before speding the money to replace it?

    the fact it is bad will be reflected in the fact that it will work, when updated, or not.
    spending money on it?? go to you rmanufacturers site, and look for an update

    Accepted Solution

    have you tried what i suggested? you don't need to replace the bios chip itself, you may just need to download the firmware updgrade from the mfg website
