I have been having intermittent CPU usage problems for about 2 weeks. Everything will be going along fine, then poof - 100% usage. I have a Dell with all legal software. I am a stickler about this.
From reading other threads, I have been monitoring task manager. The culprits seem to vary widely and include one or more of these processes at various times:
rim.transcoder (this one was new today)
snoodoku.exe (I uninstalled this game after seeing it on task manager)
taskmanager.exe (runs at up to 50% sometimes when the CPU is maxed out).
I have already: run complete virus scans with both Avira and then Norton (a new install after this problem started); Run 2 malware scans - clean; cleaned up the registry.
I did not install or change anything in the days preceding this problem.
There does not seem to be a consistent trigger for this problem - i.e. I was playing Snooduko for 30 minutes without a problem, then it started to eat CPU. Nothing else was even open.
All suggestions welcome.
As I am far far away, I am going to bed and will check for responses in 7 hours. Good night world.
