Blue / green Screen on all in one desktop

[Gwyn6]

Hello, more problems again with desk top all in one, after switching on the pc, I get a blue/green patterned screen, if I switch off and switch back on I get my windows screen, if I type in my access screen name I get revolving loading icon, then a black screen, I can only exit by Ctrl, Alt Del.

Thanks for any response.

Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• Did this happen after a recent window or software update?
• Have you made any hardware/software changes?

While you respond to that, let's try these steps: 

• Step 1: Remove discs and devices
• Step 2: Perform a hard reset
• Step 3: Run hardware diagnostic tests
• Step 4: Refresh or reset your PC. Click here: https://support.hp.com/in-en/document/c04718479 to complete the troubleshooting steps. By end of the article, you will be able to fix the issue.

Hi i did the hard reset. the screen was still locked into a green pattern, i had no alternative than to take my PC to a repair shop, diagnostics came back with no hardware problems, windows was reinstalled at a cost to me.

I can now access my pc , but if i leave the pc unattended, stop using it for a short time the screen turns green, and I have to switch it off on the button at the rear...The pc is barely out of warranty, and I've had problems with it for months.

 Thanks,, Gwyn

Thank you for posting back. 

I appreciate your efforts to try and resolve the issue. I would suggest performing system factory reset will put the computer back to the original factory settings in this way all corrupted and outdated software will be removed. 

While doing the recovery there is an option to back up your personal files. If you have not previously done one now is a good time. 

Restoring Files that were Backed Up Using HP Recovery Manager (Windows )You can also contact HP support for assistance. They can remotely access your system to help alleviate difficulties: www.hp.com/contacthp/

The HP Cloud Recovery Tool allows you to download recovery software to a USB drive. You can use the downloaded recovery image file in order to install the Windows operating system.
