Advanced PC Diagnostic Card
Motherboard Diagnostic Card, also known as a "POST Card" (Power On Self Test), is used to test & diagnose motherboard problems.
If your computer has problems powering up, freezes for long periods of time, suddenly shuts down unexpectedly or shows other signs of hardware problems - this card can diagnose your problem. It can even pinpoint problems you don't even know you have!
Is it the CMOS battery or the memory? Or maybe the processor is toast? And how about the external cache? The Debug card will tell you instantly through a series of LEDs and a codes. This card can diagnose hardware problems even before the VGA card is activated. Similar (older model) kits sell at CompUSA for $55.
