Windows 7 Video lag on ALL MEDIA PLAYERS, please help!

[ap0calyptic]

so I've been having this issue on my laptop for about a month now. It just started one day and even after reinstalling windows 2 days ago, the problem is still there.

Whenever I watch a movie any video format including high quality, mkv files my video lags, the picture just freezes, gets choppy, the sound continues to work, but video is freezing and eventually I have no other solution than click pause/play a few times, so the picture and sound gets correct again. I don't know what the problem could be, but every player does it, VLC, KMplayer, RealPlayer, WMP,MPHC, so please help me as it's driving me crazy here.

Here's what codecs I have installed if that is of any help,

K-Lite Codec Pack Full
Combined Community Pack
CoreAVC Professional Edition 1.9.5
SRS Audio Sandbox (to amplify sound on my laptop when I watch movies without headphones)

I don't think any of the codecs is causing it, cause I had only K-Lite codec pack installed 2 days ago and I still had video lag, so any idea what it could be?

here's also my laptop specs:

I would think if the video was messing up that something was degrading the performance, or was not up to the task.

You say reducing the video quality does not help, which would seem to indicate it would not be the processor. Is anything else running on the system taking processor power that might cause the slowdown? Are these videos streaming, or even when watching a DVD?

I do not know about the codecs, but did you test your system prior to reinstalling K-Lite? Are there any errors or warnings in the event viewer that might be related to the problem. Look for something that seems to be consistent around the time the video problems show up.

I would probably try to watch the system performance to see if I could notice anything that might be related to the performance problems.
