Hi @abboudi32 

 

What you describe sounds like a hardware issue. The blinking may be an indication - this is the PC trying to tell you where the problem is.

 

and try to identify exactly how the PC blinks, try to catch the pattern

 

Please, tell me exactly how it blinks

Hello,

 

Thank you for your update.

Unfortunately, I cannot help you without details.

 

  • It is essential to identify how exactly the PC blinks, try to catch the pattern.
  • If you are unable to, please create a video clearly showing the flashes and upload it somewhere. Please, share a link to watch it.

 

Looking forward to your reply.

Thank you for the video.

 

This is something I cannot fix remotely. It's definitely a BIOS or board issue.

 

 

If BIOS recovery does not help, contact local service center for HP in your country. You may try to contact local HP Support following this link >> https://www8.hp.com/emea_africa/fr/contact-hp/phone-assist.html

 

Hope this helps.
