Startup error message

[cook54]

When starting the PC, I get the error message:

511 CPU fan not detected

510 splash screen image corrupt

It takes a long time for the win8.1 to start, sometimes over 3-4 hours

How can I solve this problem?

Are there still CPU coolers?

Thanks for your tips.

HI @cook54, Welcome to the HP Support Community! Request you to follow the below troubleshooting steps 

Perform the below steps: 

If the computer does not start, the LED lights do not glow, and the display is black, 

you can perform one or more of the following actions to resolve the no power issue: 

(Click on the blue letters to get more details about each step) 

1. Examine the adapter and power cord for physical damage 

2. Test the power from the AC wall outlet to the notebook connector 

3. Start the computer using the battery only 

4. Check that the lid switch moves freely 

5. When you have completed the troubleshooting steps, there should be power available to the computer. When you press the power button, the LEDs should glow, and you should hear the sounds of the fan and the hard drive spinning. 

   • If the battery does not accept the charge or the notebook does not turn on without the AC adapter, contact HP to order a replacement battery. 

   • If the LEDs do not glow, and there are no other indicators of power being available to the computer, contact HP for technical assistance in troubleshooting a potential problem with the AC power connection or the system board. 

   • If the LEDs blink, or the computer beeps, but it does not start, go to HP Notebook PCs - Troubleshooting LED Blink Codes or Beep Codes During Startup or Boot. 

   • If the LEDs glow but the computer does not start on either battery or AC power, go to Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot.
