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.
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, hulu.com, 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.
