How can you tell if you CPU went bad, if you Motherboard went bad, or both went bad? I am pretty sure my Motherboard went bad but I do not know how to test if it was my CPU, Mother Board, or Both that went bad. I was watch a TV show online when my computer just died, the indicator light on the front of the computer started blinking purple. I tested the Power Supply with a multi-meter and everything looks good. I tested all the case fans and CPU cooling fans and they all worked. I reconnected the 24pin power connector to the mobo and everything seemed to start up just fine. The status LED’s; 2, 3, and 4 light up blue showing that everything was good there. I shut everything down and hooked up the 8 pin cpu connector to the mobo and turned everything on again and the case fans started to move like they wanted to run but instantly dies with less than 1/8 of a rotation. The IC ship right by the indicator lights looks like it may have been burned out. The black casing has a large white spot on it where it looks like it burned up. I do not have a space Processor or Mobo to test the CPU. I do not want to buy a new MOBO and have the CPU also be bad or the CPU to be bad and cause another MOBO to burn out. The MOBO I have is a MSI 970A-G46 with a AMD FX8350 Processor. If anyone knows a way to test the processor and MOBO without having a spare of the other please let me know.
You can get yourself a POST card - something like this: http://www.newegg.com/Product/Product.aspx?Item=9SIA2PN1180847
this will show you exactly where your boot process stops (displaying a 2 digit code which you can look up - eg ram bank 1 initialization).
They are not too expensive and alsways good for debugging - not sure whther that particular one is any good though, just the first hit on NewEgg.
