CPU Showing Usage At 100%: System Running Slow?
Apr 26, 2006
i know this has been posted before but none of the solutions have worked for me. i have a toshiba satellite laptop. it started running extremely slow and the cpu usage is at 100% all the time. i reformatted and reinstalled windows xp but that didn't solve the problem. i noticed when i was reinstalling windows xp, it was going slowly as it did before, and i hadn't even started up windows yet. when i would click the next button when installing it would do the same slow lagging thing. i tried everything when i did start windows too. i tried deleting the explorer.exe process and retyping it in

My PC is running superslow. Task manager shows that explorer.exe is using up to 99% of CPU usage- even though I have no programmes running.

Ive been having problems with my desktop computer. If you open up any program, the CPU usage immeaditely goes from like 0 to 100% and occassionally it will shut down and restart. Such times are when I try to run ad-aware or AVG. It will shoot up to 100%, maybe run for a minute then restart the computer. I cant even delete some files because it just restarts before they delete. So, I tried to do a restore since the last time ive been home when it was working good, about a month ago and it did nothing.

I recently allowed someone use of my laptop to access their Yahoo email over a dial-up connection. When I next used the laptop myself, the desktop had re-arranged to the default top left screen configuration and the laptop was noticeably slower in operation. It now appears to operate at 100% CPU usage, whatever programme I attempt to run. I have run Spybot (nothing detected). According to the "user" they did nothing but read their email and did not download anything (that they were aware of).

I noticed my laptop lagging a lot. I checked the CPU usage, and it was constantly at 100%. After retstart and shutdown, the cpu usage would never go lower than 100%. I did a system restore to a week ago when I did not have this problem, but this did not help. Did a spyware scan with Spybot and Ad Aware, again no help. Did a virus scan with TrendMicro, no help again.

My computer started running extremely slow. When I check the task manager it notes that the CPU usage is spiked at 100%. I checked to see what is using most of the CPU and its "explorer.exe" using about 99%.

I bought this new computer about 6 months ago and up till now no problems. I have Windows XP and now Internet usage is running ver very slow. It seems the green line on bottom takes for ever to go across. I know I only have dial up service (I know my son says i need cable but i don't want to spend any more money on Internet) but it has never run this slow before.

Recently my laptop has been running very slowly and I've noticed that the cpu usage is usually at 100%, even when most of the more memory intensive programs such as firefox and azureus are closed. Is this a problem with most lenovo laptops? I have a thinkpad T43p.

Recently found my computer running very slow almost stopped, not able to perform any function. Through task manager found CPU running at a steady 100%. Ran Hijackthis, spybot, and updated and ran antivirus - with no problems found. started in safe mode and CPU usage was at 1%. Working through msconfig i started turning services off untill i found culprit. The plug and play service is causing my problem with the CPU, but I don't know how to fix it.

Could someone please take a look at my HJT log. My CPU went up to 100% about ten minutes ago and hasn't dropped since. I didn't see any odd processes and I just restarted and it just jumped right back up to 100.

our computer is running slowly. When trying to open programs the hour glass flashes and so do the icons. I ctrl alt del to check my usage and it keeps going up to the high 90's and then back down. I have updated and ran Adaware , spybot and AVG.

First Post I have a Dell Latitude 810 XP Pro (SP3) 2 meg ram...about 50% HD unusedI have a problem with the CPU useage staying at (100%)even when I close all apps. The Windows Task Manager shows "scvhost.exe System100%" As long as I uninstall Norton I can get some e-mail response but really slow.I spent time yesterday with Dell "pay as you need" they had me run a Malware program (found five culprits) and a Spyware program (found 80 cookies)...took a lot of apps off my start menu...had me go to SP3...had me go to IE8. When done the Widows Task Manager showed appropriate low use % and all worked fine.

I'm scared to try and interpret for my own use. I have 81 processes running and have no idea which ones I can disable and which ones to not. I'm always nervous about messing with that. But, am I right in thinking that disabling something in the MSCONFIG thing at startup won't affect the program??? Can you still get to it? It just won't start up automatically, right? So, could I hurt anything if I disabled alot? So, how could I give you a list of all the processes running? I'm also having a problem with the xp update. I'm always showing that I need to update, but when I do this one part always fails. Here is what it says.
Security Update for Microsoft.net framework, Version 1.1 Service KB928366 didn't update. I'm not sure why, but it won't ever update. Also, in AOL I get an error message constantly which says this: A Runtime Error has occurred. Do you wish to debug. Line:? Error: Object Expected. I have no idea what that means and what or how to debug. I have tried repeatedly to uninstall and reinstall AOL but it keeps happening. Does anyone know what that means.

When using AOL Broadband the computer slows down and sometimes takes several seconds to refresh a page.I happened to open the Task Managerand two things came to light:I cannot get the complete Task Manager panel...It only shows TASK and STATUS..it used to show lots more.Also,and this is my problem,it shows CPU USAGE 100%.If I close AOL and go back online it is ok for a while and then starts to slow down to a crawl.

My system used to run games like UT3 and Oblivion real slick and fast. But for the past few months now it runs them real slow. I have no viruses and I have defraged a million times. I just can't seem to find out what the problem is. I have freed up a tona space on my rig, too. i have used tons of tricks to speed the computer back up, like using msconfig and disabling certain services.This is what worrys me though, I never used 2 get these: So like wtf is going down.
