    I have come accros what seems to be an unusual problem when playing videos on my PC. Basically everything was running fine a couple of days ago then all of a sudden its like my PC has lost half of its processing power but only when dealing with videos.

    Basically I have a number of videos which used to play fine on my PC but now when I play them, they jumps, the sound skips and it seems to miss big chunks of frames. It doesn't seem to matter what filetype it is. If I try to view video's in fullscreen the problem gets twice as bad. I have already done the obvious things such as scan for spyware/viruses ect, clear my temp files and tried different media players such as WMP, Winamp, VLC and PowerDVD but to no avail, the problem appears on all of them. Now I'm a bit stuck. I haven't installed any new codecs which might interfere with it and my graphics drivers are all up to date.

    Any idea's?
