I do have Norton client firewall which has been on for over 2 years. I also have Spybot search & destroy running along with disk keeper.
I've done a Belarc check and all drivers seem okay. I'm running XP pro with a 1.8Ghz processor with 768mb memory along with a 80gig 'C' drive and a 40 gig 'F' drive, I've set the appearance to best performance but the problem has re-surfaced.
I'll give Winamp a go but If there's no simple solution I'll just listen to radio whilst on-line and listen to my burned wma/mp3 discs on the DVD player.
Thanks to all.
