Slowdown after motherboard replacement

[abdullah_deniz]

Hello, the motherboard was repaired at the authorized technical service. After the motherboard repair, when I received it, I was told "Windows is damaged, you need to install it again" I installed Windows on 3 separate disks that I am sure are healthy, I tried with different RAM, I started diagnostics, I removed the battery and tried it, I completed the BIOS updates, I completed the windows updates, but it still lags and hangs, it seems like it is an old HDD. It acts as if I installed Windows 10 on a device with 1 GB RAM. HP Diagnostic did not find any problem. Is there any setting I should make after this motherboard replacement?

Thank you for your valuable time.

Additionally, when I press the Power button, it flashes the light 3 times as if it is analyzing, then it starts to turn on, but it turns on and off very slowly, it was like this when Windows was not available, I checked the disks again and again, but they are all healthy and the read and write values ​​are good enough.

Hi, Irwin

The diagnostic test hangs and never ends. It remained open for about 10 hours but was only 30% complete. Where it hangs is "Memory Test"

The problem is not solved yet, but can I know HP's warranty and replacement requirements and the countries covered under warranty? Can I repair or exchange a device I bought from Romania in Turkey? Where can I get information about my legal rights? I assume you are an authorized person at HP, can you give me some information?

Thank you very much for your help.
