Computer Running Slow: CPU Usage Above 90% In Task Manager?
Aug 26, 2006
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.

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.

My computer started running slow. I noticed in Task Manager that there were processes that ended in ' .t ' Running a search on my computer showed that there are over 100,000 .t files now on my computer. I've run Spy Sweeper, which blocks some of these from starting up, but won't get rid of them. Same with Spyware bot. What are these files? and how do I get rid of them?

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 must use the Task Master to help me to get out of a program that has locked up on me. My PC is very slow now anyway and the Task Master CU usage always shows 100% even though I may not be running any program.

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.

This is driving me nuts. The hard drive is constantly being accessed. In task manager I get usage from, services.exe zlclient.exe taskmgr.exe explorer.exe ycommon.exe vsmon.exe system idle process at 98% There are 70 processes from all users. Is this normal or what? I'm very diligent about running Ad-ware and Spybot at least twice a week. I have Avast antivirus and Zonealarm firewall and Windows defender running. I defrag once per week.Windows XP professional, 250 g hard drive, 2g memory.

Windows Task Manager shows my CPU usage at 50% when my computer is idle. The only process it shows running is the last one on the list "System Idle Pr..." What is going on here? Also sometimes Windows won't shut down the normal way and I have to just turn the power off. Could these problems be related?

I have 3 instances of CLI.exe running in the task Manager. If I close two, will it screw up some of the programs that may depend on it, or can I close all 3 instances without any problems?

I am new to Windows XP. When I had Windows ME, I only had one thing running under task manager, and that was explorer. My computer ran really quick. Under Task Manager for XP, under Processes, there is quite a bit running. I have everything unchecked under msconfig start up. What all do I need to have running under task manager and where do I go to get rid of these programs running under processes?

When I press ctrl-alt-delete, all at the same time I get a view of TASK MANAGER.Currently I have 47 processes running.I am not sure what these are, what they are doing and if they are all necessary. I am sure they are using resources that could be used elsewhere.

Had major trojans, spyware, etc. Ran Malawarebytes removed all beautifully except when I rebooted, I have nothing on my desktop except the wallpaper. When I right click on desktop, nothing. Can access Task Manager and get to files that way but no way to activate desktop. What has happened here? Also, nothing on desktop when I go into SafeMode.

My computer has been chogging quite a bit lately after booting up and continues to run sluggish...I've noticed the explorer.exe in my task manager is running extremely high. It seems to start up about 5 minutes after booting up, and continues to wreak havoc. I've seen this to be a problem everywhere from an a hole virus to RAM not sitting correctly. I've ran Ad Aware, AVG and a few others to check for a virus or anykind of malicious spyware...everything has come back clean.

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.

My task manager indicates cpu usage 55-99% when no known programs are running.Norton 2005 sees no spyware,adware or virus. SpyBot sees a file running called Xuron55 can not access this file because it is being used by another program?

I am running XP. The system is crawling. When I do a Task Manager or Ctrl Alt Delete, the little green square is full up and this is with no programs running except Windows. I am using Finity Soft Memory Manager and this program says Free Ram 54%, Memory Load Index 44%, and CPU 100%. How do I find out what programs are running other than using Task Manager which shows no programs running?

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
