My computer with intel DH55TC mother board, 2 GB DDR3 RAM, intel 3.06GHz core i3 processor and 500GB hd is randomly restarted and its Ethernet cord light is fixed.
I recommend you doing the following steps:
- Clear the cmos by removing all components from the board and disconnecting the battery for about 20-25 minutes.
- If possible take the board outside of the chassis to discard grounding issues.
- After reconnecting all internal components, make sure you do not have any USB device connected in the back. Just keep the mouse and keyboard.
