okok recently im experiencing this strange problem...when i turn on my com i can play music from windows media player, youtube, imeem etc etc...
but after about 10mins this error will pop up

i dunno if its related but whenever that error pop up and after i restart/reopen my whatever music player program..my sound system will not work...if im using windows media player i will see this error

if im playing on youtube no sound will be played...but the show will still be playing...
sometimes after the error pops out something even worse will happen...while im using my com my taskbar will suddenly change from blue to this white one...lemme show u a picture

after i restart my com..everything will be back to normal..but after about 10mins the same thing will happen...but the white taskbar will only happen sometimes...
here is the process in my taskmanager after all the error happen etc etc

as u can see no other program is using my sound system...what is the problem?
btw if im using WMP and the error comes up and if i add songs into my playlist..i can still play it but after i restart my WMP i cant play any songs anymore unless restarting my com and image 2 will appear...
help needed! thanks in advance
