Hi @MmantaS,

Thanks for the post and Welcome to HP Forums. 

I understand your computer is not booting to the desktop, it keeps rebooting. 

Don't worry, I will be glad to help.

Were there any updates installed before this issue started?

Have you installed any new hardware?

Recommend you do a hard reset. 

Turn off the computer disconnect all the devices connected. (monitor, power cable and any other peripherals connected.)

Wait for a minute. 

Connect only the keyboard, monitor, and the power cable and Turn the computer On.

If the issue, persists, do a hard reset again. 

Turn the computer On and keep tapping ESC or F2 on the computer to enter System Diagnostics. 

Run a system test on the computer. 

If you have installed any new parts to the computer, please remove it and turn the computer On. 

Also, refer to this interactive troubleshooter available at this link for assistance. 

Let me know if this helped.

Yes Chimney_83 your info was useful it helped to turn on pc. I have reinstalled windows but the problem is not gone. I think the problem is in motherboard or one of a part is broken like integrated graphics card or processor. The light in front of case are shinning, its not shined before. The pc has become very slowly when light has started to shine. Photo link...

Hi, I'd like to help as @Chimney_83 is out of the office today. 

You've done a remarkable job performing the steps. I would like to know if you have run the hardware diagnostics on the PC. The slow performance could be because of a failed hard drive. It would be better to run the tests on the hard drive, memory and the motherboard. 

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

• Turn on the computer and immediately press the F2 key repeatedly, about once every second.

• The HP PC Hardware Diagnostics (UEFI) main menu is displayed.

• Select Component tests.

Please feel free to let us know what happens. I appreciate your patience. 🙂
