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?
Please provide the product number of your PC to assist you better.
As you mentioned when you boot your PC a white screen with hp pops up and get error 500.
Try restoring the BIOS to default and check if it helps.
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.
To perform a power reset on a laptop with a sealed or non-removable battery, use the following steps:
Turn off the computer.
Remove the computer from any port replicator or docking station.
Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.
Unplug the AC adapter from the computer.
For most laptops, press and hold the Power button for 15 seconds to reset.
Plug the AC adapter back into the laptop computer, but do not connect any of the peripheral devices.
Press the Power button to turn on the computer.
If a startup menu opens, use the arrow keys to select Start Windows Normally, and then press the Enter key.
After Windows opens, reconnect each peripheral device that was disconnected, one device at a time, until all devices are reconnected.
Your laptop has been reset. After a power reset, it is a good idea to run Windows Update and HP Support Assistant to update all device drivers. See Updating Drivers and Software with Windows Update (Windows 10, 😎 and Using HP Support Assistant (Windows 10, 8, 7) for more information.
