I have a Toshiba lappy with XP Home and a Realtek sound device. After the Windows update debarcle a few days ago I have sorted the problem with the Hotfix that seemed to fix most peoples systems. But now my whole system struggles to even play a song or movie in WM without stuttering. Most other apps also stutter or fail completely (like Protools ect;) within a short time. I notice that my CPU usage fluctuates wildy and does not seem ever to stop, even when idle. When I open any app, even just Media Player, CPU is pegged at 100%. I have more than 50 proccesses running at idle which i dont remember ever seeing before (but cant be sure) , I dont know if this relevant? ...and I notice a comment like "TPM gone or TMP Not working" during boot up, again i cant be sure but I never noticed it before and know if it is related. I really need some help and guidance please, so I can get back to work, all I seem to be able to do now is check mail and browse help forums... Cheers!
