How to Use

Use this card to troubleshoot your motherboard problems. Sometimes your computer will not boot. Use this diagnostic card to see the POST (power on self test) codes that the BIOS commands the motherboard to perform. Each motherboard has a BIOS chip which is a device that initializes all hardware components on the motherboard such as CPU, memory, video card, etc. During the boot up sequence, your BIOS will also generate what is called POST80 code. Each code can be referenced in a manual supplied to help determine the problem with the motherboard. If your code is NOT LISTED in our manual, chances are you have a newer motherboard. Visit the manufacture of your BIOS and download the manual of your BIOS direct. In most cases, where the last post code is displayed on the POST card is generally the problem area. For example: If you have an Award Bios on your motherboard, and you install this card. Turn on the power to your computer. Your computer stops booting, but the POST card shows a code of “01″. This could mean you have a faulty CPU on your motherboard because the BIOS told the CPU to start, but the CPU did not respond. If a piece of hardware does not respond during a boot sequence, then the motherboard will not finish POSTing.
