Hp Omni 120-1209l powers on, intermittent black screen

[hiimmei]

I have had this pc for 5-6 years and this is the first time that it has happened. it just stopped turning on. there are extremely rare times that it would turn on fine, but most of the time it's just a black screen. it would power up but has no display and the fans(?) would vibrate and the mouse works and turns on but not the keyboard so i cannot troubleshoot using it.

do i need to let this one go or can it still be saved?

@hiimmei,

Thank you for posting your query on HP Community,

Let's try these steps here: 

Perform a Hard reset on the PC: 

Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset". Use the following steps to perform a hard reset on a computer:

1. If Windows is open, click Start and then Shutdown.

If Windows is not open and the computer has power, press and hold the power button on the computer until the computer shuts off.

2. With the power off, disconnect the power cord from the back of the computer.

3. With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.

4. Reconnect the power cord and turn on the power.

Next thing, I would suggest here is to attempt a Bios Recovery -   HP Desktop PCs - Recovering the BIOS
