Power Supply Light Blinking When Plugged to Motherboard Only

Media Center m1050y
Microsoft Windows 7 (32-bit)

Hello,

 

I the power supply light of my Media Center m1050y is blinking and the PC does not turn on at all. So I tried the troubleshooting sequence posted here in the HP Support site, and after unplugging all the cables and replugging them one by one, it turns out that the light blinks only when the PS is connected to the mother board (the connection is a white, wide plug with about 12 pins - pardon my ignorance on the actual name).

 

I looked on the internet about trying to narrow the cause on the motherboard and I unplugged the front USB ports, the fan, and other "solutions" without any luck. Does this mean the motherboard is fried and either I need to replace the motherboard or look for another PC?

 

Thanks!

What troubleshooting sequences did you try......was it this.   Suggestion: get a hair dryer, and use it at the rear vent. See if the light stops flashing. Read about the hair dryer tip here.

Hi @Dean

 

Yeah that's the troubleshooting wequence I tried. Also, I tried the hair dryer for several minutes and nothing. I don't know what is the rational behind it but, as I suspected, it didn't work.
