Well, the RAM seems off. Try taking one out and see how it goes.

Before upgrade, the laptop is 1 GB RAM only.
after addition of 4GB RAM, the total RAM now is 5GB RAM.
Thanks for reply my thread , Asura.

Are the latest drivers Installed for both the video and sound card? Is "streaming" fine for other devices on the same network?

Yes. I already install the latest version for both video and sound card on my uncle laptop.
streaming online also no sound and slow motion playback video.

It may well be a hardware Issue, as a consequence of the said repair.

Are other devices on the same network streaming fine? To eliminate the probability of anything software-related, hit a clean Installation of Windows with only the bare essentials Installed thereafter. If It's still the same, take It back to the person(s) who're responsible for the damage.

Given It was running fine prior to the repair, It certainly does point to a hardware Issue as a result of their (poor) workmanship.

If they fail to reply by phone, physically attend the premises.
