"system" cpu usage 100%

by skhoon / September 8, 2009 9:40 AM PDT

Hi, this issue has been bothering me for awhile, and I did some search on my own about this issue, but I couldn't find much helpful advice. So I decided to ask for a help.

I currently have dell laptop inspiron e1505 with 1.83ghz, 1gb ram, & windows xp home edition. I bought this computer 3 yrs ago and it has gotten slower; thus, through a friend I reformatted the computer about couple months ago. My friend got it reformatted through her school, and the school installed all the drivers for me, so I don't exactly know what drivers are installed. anyways, the issue is that since I reformatted the computer, (I cannot exactly remember if the problem occured before or after I installed all the programs such as adobe suite, office tools, firefox, etc.), the computer would freeze up randomly without a notice. Thus, i checked Windows Task Manager, and under processes tab, "SYSTEM" would be eating up 95-100% of cpu. I tried closing all the processes and services (such as automatic updates, nvidia driver, etc.) that are unnecessary in running the computer, yet the SYSTEM would still be using 100% cpu and the computer stays slow. I checked the Event Viewer to see if there's an error, but couldn't find anything. I ran virus checks using both norton antivirus and avg, but couldn't find a significant threat. I uninstalled norton and just kept avg., thinking having two antivirus programs may be the problem, yet the issue still occured. I tried removing my battery couple times after reading some advice, yet that also didn't solve the problem.

I can't really find a consistant pattern, because sometimes the laptop would work just fine. But my opinion is that it may be related to something video, because I think it occurs more often when i'm watching something on youtube,, other video-websites, & avi files through itunes or gom player. however, that also is not inconsistant. once the laptop slows down, even after I close all the applications and unnecessary processes/services, the laptop stays slow with 100% cpu usage mostly by "SYSTEM". the problem often disappears when I restart the computer, but sometimes it doesn't go away even after I reboot the system.

I really don't have a clear idea of what is going on and what is causing SYSTEM to take 100% cpu usage. Please, help me out. Thank you.

System Idle Process is the amount of the CPU that

System Idle Process is the amount of the CPU that is *NOT* being used. You want it to be 100% during times the machine is not doing anything.

I see you mentioned batteries
by MarkFlax Forum moderator / September 8, 2009 7:33 PM PDT

This being a laptop, when you run it from the mains, do you use a UPS? I've pulled this from another web site's forum discussion;

"After searching through the Microsoft Windows XP Knowledge Base a bit, I came across several articles mentioning this problem, and the cause in those cases was battery related. My computer is a desktop, so it doesn't rely on battery power like a laptop, but I have a handy BackUPS from APC, and Windows was having trouble with it. All I had to do was unplug the computer and plug it into a normal outlet, lol. Apparently SP2 provides a hotfix for this, but I think the KB said I can request the specific hotfix since my drivers aren't SP2 compatible".

If that is not the cause, you might want to try and delve deeper with another suggestion in that forum, Process Explorer by Sysinternals.

I hope that gives you some ideas.
