I am sorry you are having problems with this unit but let me help you.
There are some troubleshooting steps I would like you to try:
- Disconnect all components from the motherboard (HDD, Video Card, Audio Cards, power supply, etc) for about 20-30 minutes.
- If possible place the unit in a non conducted surface like glass or wood.
- Reconnect some components to get minimum configuration (1 stick of RAM, 1 HDD. No Video cards or audio cards).
Let me know.
A video would help to have a picture of what you are talking about; however, based on the information you have provided and the steps you have done I would say that may be a problem either with the motherboard or the processor so I recommend you contacting our technical support for them to help you checking the unit and replacing it if necessary.
Here you have the contact information:
