Windows 7: Helping Friends make computer need help!

where abouts on the mobe is the black square?

next to the ram, close to the corner

is the mobo the one in your system specs? if not could you tell us the manf/model

the mobo is the one i said in the post its msi 890GXM-G65

Sounds to me like you probably fried the motherboard ...

The chipped black square is likely a MOSFET, or power control transistor. When they get too hot from over-voltage or current, the black epoxy that they are made of will often fracture, and the broken piece will frequently go flying. That was probably the bang that was heard. The smoke likely came from that component, or other components that were supplied any voltage or current from that device down the line.

EDIT: @ illway1:

I've attached a screen shot of your mobo. Which area was the broken part located in?


And possibly the RAM and CPU as well...

Beep codes for AMI,Phoenix and Award bios. Post Beep Codes, AMI & Phoenix/Award BIOS error codes I'm going with the fried MB as well. Fabe
