Question Cant Watch videos/streams or sometimes even listen to music while playing games. brand new pc

[Kudrou]

Recently got a new pc i9-14900kf, 4070 ti super, 32gb 6400, good temps.
So the lag im getting isnt frame drops. Basically if im trying to watch a stream and play the stream will lag and not play unless i alt-tab.
same with videos if its on HD it will lag if i am playing but fixes as soon as i alt tab.
the 2nd part of this issue is sometimes while the stream/video is lagging it starts to lag the game aswell via input lag. Ill randomly get like up to 5 whole seconds of JUST keyboard input lag until i alt tab and close the video/stream. PLEASE help

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:

Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

Did you install the OS for your platform or did they do so at the store you purchased the system from?

Has the system ever worked properly?

Are you using a wired or wireless network?

Same question for keyboard and mouse, wired or wireless?
