Rapidly Slow Down The System - CPU Usage
Oct 9, 2009
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 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

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.

my laptop which wont post unless I rapidly tap the F8 key as I press the power button.The laptop then boots normally and runs fine.If I then restart it after installing a program, using system restore etc it wont reboot, and I have to resort to holding down the power key to switch off and then back to tapping the F8 key again.If you don't tap the key really fast it wont post either.If anyone could point me in the right direction I would be very grateful as Evesham no longer exist.I have read lots of info on the net and tried removing hard drive,memory, cd, holding the start button for 30 seconds to reset with battery out, but to no avail."

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.

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).

Several weeks ago, we had a blackout. When I rebooted my PC, everything was slow. Programs, internet, everything. Looked all over the web for a solution but found nothing. Wound up reinstalling Windows, and the PC was running like new again. Two days after the reinstall, we had another blackout, and I'm right back to where I was before. I've scanned for spyware, defragged the drive. I'm a novice, so I'm not really sure what else can be checked.

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.

I have a laptop operating on Windows XP. Recently my computer has become extremely slow. I have gone into task manager and noticed that the CPU usage is quite high, even when there is very little running. At times the system idle will hover in the 90% range, however the CPU usage will also stay in the same range. (As far as I know, if idle is at 90%, than CPU usage should not be higher than 10%). I can't figure out what else is running that is making the CPU usage run so high. I have run various virus and spyware tests and all have come out clean. I have used cc cleaner to clean my registry and even update some of my out of date drivers but the problem has continued.

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.

I have a compaq(aka junk box) 3.2 celeron(crap) PC.It just started running like a 95 machine a few days ago. I did ctl, alt del and got a look at proceses running its system, not system idle. It runs at 99-97. I look at cpu usage its maxed never moves. i did a back up of my pictures to disc and did a "destructive" windows reinstall from the recovery menu seeing as cheap compaq crap doesnt give me a windows disc so i can do it the old fasioned way. Is the destructive reformat doing a full format. i prefer zero filling a drive with issues like this. what else could make it do this 100% usage thing right out the door when i install windows.

I recently installed a winTV card in my computer, ever since that I have noticed that when I press ctrl, alt and delete, the cpu usage appears to be 100% full whenever I try to open an mpeg file I have recorded from the TV card. it is a pentium 4 2.8 ghz processor.

Why would the cpu usage be on constantly 100% in xp, with barely anything running. that doesnt seem as if its right ... does it?

As soon as I turn on my laptop, my CPU usage in the Task Manager is at100%. There are no programs running in the Applications tab and theprocesses using the most memory are explorer.exe (~9000K) andsvchost.exe (~6500K).My computer doesn't seem to be running excessively slow or getting hotdespite this.
