System process takes 50% of CPU
Hi,
I have this ongoing problem with the system process taking around 50% of the CPU time. It went away for a few weeks and now it's back with a vengence! I have Norton 2006 Anti-Virus, Spy Doctor, Zone Alarm all up to date and everything fully scanned. I am behind a router and have XP firewall. All Windows updates applied with SP2. I have tried stopping all processes that let me but the good old System process still reports between 49% and 53%. If I go into Safe mode with Networking all is OK. If I use msconfig and turn everything off and re-boot, the System process still reports 50% or thereabouts. I can't find any pattern as to why the problem went away and then came back. It's a real problem as the PC runs slow and the fan is full blast all the time. I read that this is a common problem but no-one reports any solution. I have uninstalled quite a lot of stuff to no good effect. I don't install too much anyway and I'm particularly careful not to install dodgy music downloaders or anything like that. Any ideas before I reformat the disk and re-install everything? Regards, Vic Russell |

System process takes 50% of CPU
You need to find the specific system process that's taking all (there are
lot of sub-processes tied to the 'System' process) the CPU resources and slowing down your PC. To do this try Process Explorer: http://www.sysinternals.com/Utilitie...sExplorer.html Once you have Process Explorer installed and running: In the taskbar select View and check 'Show Process Tree' and 'Show Lower Pane' options. (This will provide the detailed info you need) Next click on the CPU column to sort processes by %CPU usage. Then click on and expand the 'System' process and identify the sub-process that's using most or all the CPU %. Click on and Highlight the sub-process of interest, right click and from the options listed select: google, This should display what's out there on the web about that process. Note: some entries like Explorer, System process and svchost may need to be expanded to show the detail, (sub processes), in this case click on the + located to the left on the entry.

Additionally, when you find out what is the process that is hanging up
your machine, goes to PROPERTIES in Process Explorer and then in THREADS. Put here the process on the top of it. For SVCHOST this is necessary. Regards. |

System process takes 50% of CPU
Im also having this problem, at random times my CPU usage will spike to over 50% and stay there for random amounts of time. I looked in process explorer, and there is no "child process" under the "system" process... here is a screenshot... http://img88.imageshack.us/img88/3682/untitledhk9.png -- Freeway |

System process takes 50% of CPU
Okay, So I registered just to post this. I DL ed the process tree thing from previous post. At first, it cannot identify which sub process in my system process that took most of the CPU %. a few seconds later, I foolishly (and fortunately) decided to just kill all the system tree, this caused my comp to go BSOD and blahblahblah. after one restart later, the system CPU usage went down to 5%! I dont know what did it, but it just works like a charm. -- freedude |

System process takes 50% of CPU
new HP with XP SP3 workstation System process takes 50% CPU. After some research ..... i think it is the screensaver/lock workstation process that holds 50% cpu, even after unlocking! What works for me: Just a simple "right-click" on my desktop drops the CPU usage... Not solved, but easy to handle. Hope this could help.... DickDelete -- dickdelete |
