I have multiple questions related to high CPU and memory usage during play of live video in internet.

Problems:

CPU at 100% and RAM at 90% during playing online video like Amazon Prime, ZEE5, Netflix. Except ZEE5, others are still watchable as there is no lag, but ZEE5 causes videos to freeze.

Computer System: 4 year old. Gigabyte GA-N3050M main board with onboard Celeron Dual core CPU @1.6 GHZ. 4GB DDR3 RAM @1600MHz. A-DATA Ultimate SU650 3D NAND 120GB SSD. Sony 21 inch TV as monitor. Monitor connection is VGA. Motherboard supports a maximum resolution of 1920x1200@60 Hz in VGA mode and a maximum resolution of 3840x2160@30 Hz in HDMI mode. I use VGA. It has one 1 x PCI Express x4 slot, running at x1

Questions:

  1. The motherboard is capable of descent resolution then why the CPU starts to struggle at playing online video?

  2. If I connect the monitor to HDMI port will that lower the burden on CPU and RAM ?

  3. Will it be possible to install a graphics card on this board and if yes, will that make the video playing smoother and lower the CPU and RAM usage?

  1. Because the CPU is having to decode some/all of the video stream data. Video codecs have varying amounts of demand on a CPU.

  2. Unlikely.

  3. Yes, look got a PCI-e x4 card like a Geforce GT 710. It should reduce the load on the CPU & RAM.
