Black screen

Black screen, computer won’t turn on but orange led light blinks, it makes kind of a scratchy noise instead of a beep

@BrittneyGermain Here's what you need to do, to identify the issue and resolve it accordingly:

• check if it works fine on an alternate/external monitor.
  • If it works fine on an alternate screen, please Perform a hard reset, Attempt a BIOS recovery  and then, Run the System Diagnostics tests.

That didn’t work. I got a new motherboard and I made sure the ram was in place and tried a BIOS reset. F12 key blinks orange and it sounds like the hard drive is trying to turn on but fails.

@BrittneyGermain Where did you get the new motherboard from? Is it HP or local? That said, could you share the results of the hardware test I had requested? if not done, here's what you may want to do:

Hold the power button for at least five seconds to turn off the computer.

Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.

On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests.

Click Extensive Test.

Click Run once, or Loop until error.

While the test is running, the time remaining and test result for each component display on the screen.

If a component fails a test, write down the failure ID (24-digit code) for when you respond back to us.

 Computer screen looks like as it was never turned on. The screen does nothing when I turn it on/off or press esc. I can’t do anything with it and it doesn’t work when plugged into a different monitor

@BrittneyGermain You haven't mentioned where you got the motherboard replaced from? I suggest you contact the same tech and have them replace it again, and have them look at the DC power connector as well, considering the device is no longer powering on, if the motherboard was replaced via HP, here's what I suggest you do:

If you have an HP authorized service center near by, you should be able to take it to them and have it checked,

Here is a link to HP Service Centers, by Country/Region: Click here

Or, I suggest you talk to HP support and discuss your options, follow the below steps to get started:

1) Click on this link - http://www.hp.com/contacthp/

2) Click on Sign-in or select the product using the below step:

3) Enter the serial of your device.

4) Select the country from the drop-down.

5) Click on "Show Options".

Fill the web-form, to populate a case number and phone number for yourself!

Also, if you are having trouble navigating through the above options, it's most likely because the device is out of warranty, if yes? please send me a private message with the region you are contacting us from,
