hi, about a month ago my vaio laptop started freezing on youtube . i mean everything was frozen and i had to restart it manually. and then it started freezing on avi files.wether i play the avi file on wmp, vlc or real player, the duration of the freezing was about a minute or two every 20-30 minutes on both the audio and the video. so far, this is what i ve done: 1-updated the video card . and everything else through vio update. 2- installed k lite codec 64 3- ran disc cleanup and registry cleaner through vaio care . 4- installed the latest realplayer version. 5- ran sfc scannow . i dont really know the results for the scan because i was away from the laptop the minute it finished. 6- scaned the computer with avg anti virus 2012 and no viruses were discovered. results: the duration of the freezing decreased. now it freezes every 15 - 20 minutes for a second or 2 and the video fast forwards to keep up with the freezing and the sudio stops during freezing. and its really annoying because sometimes it freezes like 10 - 20 times a day. could it be from bitlord 2.0? my system specs: vaio laptop vpcea25fa windows 7 home premuim service pack 1 and 64 bit 4 gb ram 2.27 gh cpu ati mobility radeon hd 5145 graphic card. plz reply to me as soon as u can ,any help is appreciated. take care everyone.
