i Just bought the HP Pavilion 20-a228l AIO Desktop PC and when i update the bios and after it reboot, the screen blank. only the switch on button is light for a few seconds and then it switch off.
At every time i switch it on, the sound of the fan and hard disk running appeared and for a few second, it automatically switch it off back.
Hope somebody can help me with this matter and i really appreciate it.
Thank you
