Hi, whenever i open My Music folder from the start menu, and some other programs like World of Warcraft, in Windows XP the CPU usage jumps to 50%. When i look at the processes in Task Manager "explorer.exe" is using 48-51% constantly and won't go down unless i end the process and run it again. I've tried all Anti Virus and Anti Spyware software and nothing has worked so far. I've gone into msconfig and run in Diagnostic Mode and i still have the same problem so it's nothing that is starting up. I i was having this problem before but then i reformatted my HD and reinstalled Windows XP. it's been 10 days since then and untill today it started doing the same thing. If anybody has some other ideas for me to try i would really appreciate it.
