Hey there! @jt1313, Thanks for stopping by the HP Support Forums!

I understand you have issues booting into your PC.

Don't worry I'll try to help you out.

Did you make any hardware or software changes on your PC?

Have you tried checking with a different video cable?

Are you able to boot into BIOS your PC?

Please provide the product number of your PC to assist you better.

In case an item was changed in the BIOS, such as the primary monitor device setting, use the following steps to reset the BIOS back to its default configuration:

You can use these steps even though you cannot see anything on the monitor.

1. Turn on the computer and repeatedly press the F10 key for eight seconds.

2. Press the Down arrow three times.

3. Press the Enter key two times.

4. The computer restarts.

If you are able to boot into BIOS try the steps recommended below to restore BIOS to default.

1.    Turn off the computer and wait five seconds.
2.    Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3.    On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4.    Press F10 to Save and Exit.
5.    Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6.    Follow the prompts to restart your computer.
 

Also, I would suggest you enable Fast Start-Up on the system and check if it helps. To do this, follow the steps below.
1. Open Control Panel and go to Power Options.
2. Click/tap on the Choose what the power buttons do link on the left side.
3. Click/tap on the Change settings that are currently unavailable link at the top.
4. If prompted by UAC, then click/tap on Yes. 
5. Ensure that Turn on Fast Startup is checked.
6. Restart the computer.

Try updating the BIOS and chipset driver on your PC and check if it helps.

You can try updating the drivers on your PC using HP support assistant.

Refer this article to know more information about using HP support assistant.

If the issue still persists after trying out the steps try the steps recommended below.

In Windows, search for Command Prompt. In the search results, right-click Command Prompt and select Run as administrator. Then click Yes.
In Command Prompt, type sfc /scannow. Make sure to include the space between sfc and the /.
Press Enter and wait while System File Checker scans for corrupted files.
When scanning is complete, the results are displayed on the screen.
If the file checker found and replaced any corrupted files, restart the computer and check the performance.
If the file checker did not find any corrupted files or found corrupted files but could not replace them, go to the next step.
If System File Checker finds corrupted files but cannot replace them, use the Deployment Image Servicing and Management (DISM) tool. DISM checks the corrupted files; then downloads and replaces the files using Windows Update.
In Windows, open a web browser.
   NOTE:
You need to be connected to the Internet to use DISM.
In Windows, search for Command Prompt. In the search results, right-click Command Prompt and select Run as administrator. Then click Yes.
In Command Prompt, type dism.exe /Online /Cleanup-image /Restorehealth. Make sure to include the space before each / in the command line.
Press Enter and wait while DISM works. This might take several minutes.
If DISM finds corrupted files, it replaces them using Windows Update. If this occurs, after DISM is finished, restart your computer and see if the performance has improved.

If the issue still persists try running a system diagnostics test on your PC and check if the hardware on your laptop is functioning correctly.

Refer this article to know more information about running system diagnostics on your PC.

Hope this helps!

Have a great day! 🙂

Hello

I have the same problem and I´m desperate. We bought 5 desktop computers Pavillion 590-POxxx, and the same happen to all of them, the screen goes black for 1 to 3 seconds, it happens randomly and very often, it happens with different windows versions, and all drivers updated. It happens in different offices with different cords and monitors, and it happens without any other software installed. I sent the computer two times to HP, but they said they did a 96 hours intensive test, but everything it´s fine for them, so I´m in an end way. Could you solve this problem?

Regards

Please if you delete my email send me an email with an explanation. Yesterday I wrote here saying the same and it dissapeared. Thanks

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

• If not done already, check if it works fine on the BIOS screen to identify if it's either a hardware or a software issue:
  • If it works fine on the BIOS (Accessed while tapping F10 during a restart) it's a software issue & I suggest creating a new user account to check if that works better, for starters)
  • However, if it doesn't work within the BIOS either, I'm afraid it's a hardware malfunction.

While you respond to that, I have a few more steps that should help: 

Perform a power reset (no data loss) using these steps: Click here, proceed to next step if this works

Attempt to run a test from the HP hardware diagnostic tool, using this link: Click here for details.

If the issue appears on the diagnostics, it could again, determine a hardware failure,

If they don't appear on bios & the hardware tests passed: please update the BIOS & Chip-set drivers from the HP website using this link: Click here

if the issue persists, reinstall windows using the recovery partition or the recovery media to fix the issue,
use this link for details on performing the recovery: Click here
