First, you should always provide system specs when seeking help.
Hold down the Windows key (left, with the flag on it) and the R key (for the Run command) and let go. Type dxdiag and hit OK. Choose to Save all information to your Desktop, then open it and copy and paste here the first section. Then copy the first few lines under Sound Devices, down to Driver Provider. No personal info will be sent.
Then tell us what your cpu cycles are from the Task Manager (hold down ctrl, alt, delete and let go).
Then tell us if you see any conflicts in Device manager (paste devmgmt.msc in the Run command and hit OK)
You can also look in Event Viewer for error reports (eventvwr.msc in Run command)
For videos doing stop and go, go to http://www.speedtest.net/ and tell us the result.
That will help diagnosis things.
Kenobi must look to Christ!
that dxdiag command, never saw that before
everything is okay according to that
BUT
In task manager, I saw this recently, too, it says I am running 5 or 6 copies of CHROME, I only have 2 windows open, so, I was wonderng what in the world would cause that
my cycles are all 00, 01 and 02’s
my performance is using half my RAM, and 10-45% of my CPU, depending on whether I am typing or whatever it seems, but 1-2% when just looking at it
deleted one of the Chrome’s, okay, but the next one killed this window, it did restore when I started chrome again :)
