Good evening, I have this notebook with a strange defect. Lights up, loads the windows, after about 2 minutes, the volume control bar starts flashing, and the hard disk begins to light up again, then at some point, the notebook restarts, no longer seeing the hard disk . If I disconnect the devices and hard disk player, the problem does not occur, when they attack the hard disk and the reader, the problem occurs. I attached a new hard drive, and I tried with an external reader usb, but even in that case, as an attack on the player, the problem returns. It could be a problem with the northbridge or is a power problem?
Thank You
