The computer runs just fine for days if i just use the programs i have open. The problem is when i start programs like limeware(filesharing), rappelz (game) (also other games), live help messanger (support IM prodgram for homepages) and some other programs. If i load the program with for example open firefox and all its pages and start winamp etc it works ok BUT if i teh also start one of the programs listed above then windows 7 freezes in a wierd way. The music from winamp just keeps on playing like its totally fine and i can even move my mouse but nothing is happening, its like its a screenshot infront of me. if i click some then the mouse also freezes but the music keep playing. However if i have no load on the computer and did just start up the computer and try to start one of the programs above then it starts up just fine and as long its running everything works fine. If i start up the computer and fool around on it for a few hours and then but no load on it and try and start one of the programs above then MABYE windows 7 freezes (it freeze for sure if i put load on computer and start it). I used to have this problem with windows mediaplayer classic but i updated/installed some drivers i cant remeber and then the problems for that program went away. It seams to be related with internet based program (however it have never happen on firefox startup, email startup and more) AMD Athlon 64 X2 Dual core processor 6000+ 3,02 GHz 2gb (ran a memorytest and no errors) 64 bit ultimate Any suggestion what might be wrong and how i can fix it?
