I have a quite annoying problem with W2K SP4. It might be related to process priority management. Whenever I run an application that needs a lot of CPU, all the other process seem to "freeze". Sometimes it is the antivirus (avast), the explorer.exe process, when I copy something from the DVD unit, or whatever else, it takes the 100% of the CPU and the other applications work poorly for a while. I can specially feel this problem when listening music on an mp3 player (VLC, or Winamp)… the quality of the sound is poor or the music stops from time to time.
I understand that some applications need CPU, but it seems looks like they take the 100% of CPU resources. I tried to raise the priority of the VLC mp3 player to "real time" in order to compensate for explorer.exe or whatever else is taking CPU, without success.
I don't think it is a virus problem, since when the greedy application finishes its execution, CPU usage descends and everything works fine again. No troubles with svchost, services.exe stuff...
I am using a pentium 2.66 GHz, 1GB RAM. Not exactly a high end machine but not that old to have these usage problems. I ran the same SW applications on an inferior machine smoothly without any trouble.
Thanks a lot!!!
