|If a logo screen is displayed while booting...|
The model is often displayed on a logo (graphical) screen early in the boot, but it's often not as specific as the specific model number.
The model, sometimes the make, of a mboard in a generic desktop system is usually printed on the mboard's surface in obvious larger characters, often between the slots.
If the board doesn't have that, there may be a stuck on label on it
- on the top of the parallel port that has the model number
- on the mboard surface - the one with the model, or mboard part number if it's from a brand name sytem, on it often has a bar code on it too.
If you are able to boot the computer and get a display....
The bios string is usually a long string of numbers/letters at the bottom of the first black screen as you boot your computer - it often begins with a date - usually you can press the Pause key to read it and copy it down.
Press any key but Pause to continue booting.
It could also be higher up the screen under or beside the bios version line, e.g. under or beside Award or AMI or Phoenix...
Post that bios string here, and include any dashes, etc.
Please make sure you copied it right. Most Award and AMI Bios strings do not have spaces. Newer Phoenix bios strings, based most often on those for Intel mboards, are often like so: xxxxxxxx.xxx.xxxxxxxxx
If you have Windows running on it...
Go here, download BIOS AGENT.
Run BIOS AGENT to find your bios string.
- here's the link that downloads Bios Agent
The current Bios Agent calls the bios string the Bios ID.
Tell us the Bios ID it finds, or everything Bios Agent finds, and include any dashes, etc
Sometimes the bios string is not visible because a logo screen is displayed overtop of it while booting. In that case, if you are not able to use Bios Agent, go into your bios Setup while booting. Sometimes the bios version date, and sometimes the bios version number, are stated in the bios Setup screens somewhere, and/or some show the identifier part of the bios string at the top of one or more screens.
Or you could try disabling the display of the logo screen if there is such a setting, or disabling fast boot or similar, which often disables the logo screen.
Tell us what you find.
