Problem with sound (thinkpad edge e540)

Hi!

I have thinkpad edge E540 (intel i5, 8gb ram, fullHD) with windows  7 64 bits.Sometime when i start winrar or other program like power menegment and listen music, the music is disturb for a moment. 

Somethime the operation system freezes for a moment.

What you think, these problems are from the operation system or the drivers or hardware.

Hi bacho10 If you switch the power plan settings to Maximum Performance, would the problem persist?

I switched power plan settings to Maximum and minimum, but nothing.

I ubdated bios with last version.

I think this problem come from Windows or process priority, but how to change priority for sound, not for player?

Hi bacho10

1. Please refer to this KB.

2. Download this and check if the DPC is high.

Hi bacho10

1. Would the problem persist if external headphone / speakers are plugged in?

 

2. Go to Control Panel > Lenovo - Update and drivers to ensure that your BIOS and hardware drivers are up-to-date.
