replacing usb ports toshiba L755D

[mrkfmcliq]

My usb ports on my Toshiba Satellite L755D-S7340 have stopped working.

I have tried to reset the BIOS and most other fixes I have found on the net!

How do I open my laptop and see if the ports are physically damaged.

I also get a "Critical cooling system malfunction" error from time to time.

Do these have anything in common!

Hi, when you go into the Device Manager, do you see in the Universal Serial Bus controllers a yellow triangle?
