Hi fedzera,
The 8 beep error code indicates a display failure, try running the hardware diagnostics by tapping the F12 key on a few times during startup until you see the ‘One Time Boot Menu’ appear.
At the one time boot menu, press the down arrow key to highlight ‘Diagnostic’, and then press Enter to begin the hardware diagnostics.
If the test fails, please make a note of any error codes listed. You can also refer to the link below.
