s12 hd playback laggy

[Guest marind]

Maybe im expecting too much out of it but ive seen videos of the s12 playing back 1080 smoothly and mine struggles immensely.

Ive googled it to death, tried klite codecs, different nvidia graphics drivers, MPC, VLC. Ive installed asrock tuner and overclocked it to 2.1 ghz and it still struggles. Ive uninstalled mcafee lite, tried selective startup aned cancelled some background apps. The only thing I havent tried is fresh version of windows 7 without the bloat, as I havent got a windows 7 disc this may be tricky.

For info; 2gb ram ion version bought jan2011.
