SODIAL(R) 4-Digit PC Mainboard POST Diagnostic Analyzer Test Card

This is a 4 digit add on card for motherboard repairs(fits on PCI slot, even works on dead motherboards). I have been using this for a while now. I found this very useful for my motherboard repairs. It basically lets us detect the problems in motherboard.

Here is my diagnostic card -

How to use this ??? 

This article explains how to use a motherboard diagnostic card to troubleshoot and diagnose a wide range of hardware and BIOS faults.

While some computer hardware issues can be accurately diagnosed using beep codes, system error messages and experience, sometimes a more fulsome technique is needed to resolve more difficult hardware issues. For those purposes, technicians often use motherboard diagnostic cards to help them find problems and resolve them quickly.

What are Motherboard Diagnostic Cards?

Motherboard diagnostic cards (a.k.a. PCI POST cards) are electronic devices that fit into the PCI or ISA slots, or sometimes a USB port, from where they can analyze hardware issues and BIOS faults. These troubleshooting tools can usually find problems with the BIOS, video, CPU, hard drive controllers among other components.

A computer system has a number of failure points and while the cause of some issues will be quite obvious, at other times faults can be very difficult to find. Motherboard diagnostic cards can help technicians to quickly pinpoint the cause of system errors or hardware faults. This saves on time that would otherwise be spent in the trial and error process, and prevents waste of money purchasing the wrong solution.

How to use a Motherboard Diagnostic Card

By and large computer diagnostic cards are easy to use, with many offering plug and use simplicity. Here is how motherboard diagnostic cards are used.

Plug the card into the available USB port, PCI or ISA slot and switch the computer on.

Watch the card’s display for failure messages. At system start up, the computer will start the POST (power on self test). The computer does this to determine what components are installed and whether they are working properly. If a test fails, the diagnostic card will halt and display an error code that identifies the fault it has found.

To decipher what the code means, reference the accompanying POST card’s documentation; they usually have a list of all the codes that the diagnostic card recognizes, along with the possible cause of the error.

Diagnostic Cards Interfaces and Options

The more traditional versions of motherboard diagnostic cards use an ISA or PCI interface, but solutions with a USB interface are now available. USB diagnostic cards can be used without opening the computer to install them, which offers greater convenience to the technician, assuming that there isn’t a problem with the USB ports as well. There are even PCI and ISA cards that have detachable displays that allow the error codes to be seen even if the case is closed.

You can get error code manual with this when you purchase it. Or you can get the code manual on web. Here is the link - 

Or you can google every error code you get from the card.
