Hello @syasa 

Thank you for posting in the HP Support Community.

3 blinks of the CAPS lock is a clear sign of memory slots or memory chips.

If reseating the memories didn't help, you should try with different chips (completely different ones) because your existing one(s) may be broken.

If you have 2 chips and 2 slots, you can test by removing one of the memory chips and leave only the other one to see if this is a failure in one of them, and this way test the 2 chips one by one.

If nothing helps, it may be the motherboard or the slots themselves. If it doesn't help, you need to have the PC serviced. How to contact HP Support team for your country/region >> https://support.hp.com/id-en/contact-hp

Let me know how it goes - provide your feedback and/or update.
