In the meantime, I'd like to suggest you run diagnostic tool to check hardware on the system by following steps below.

1. Power off system.

2. Power on system, quickly start tapping F12 key continuously. In the menu, stroll down to Diagnostic and then click it. After quick tests, click Hard drive, and then Thorough Test Mode. Please report back any error code.
