Extremely Slow Computer - CPU Usage Is Quite High
Jul 9, 2009
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 I have used cc cleaner to clean my registry and even update some of my out of date drivers but the problem has continued.

When I run spybot or my antivirus my cpu goes to 100% and eventually overheats my laptop. I suspect I have a trojan/virus that's making the cpu run so high but I cannot scan my computer to find the culprit.

I have been having this problem for a couple of days now. I was listening to music which had been skipping for a while but not to bad and suddenly everything froze. i killed winamp and hit pulled up the task mgr. cpu usage was staying around 100% different processes popping up to the top. i downloaded process explorer and it has a file highlighted in dark red wmiprvse.exe i read this could be a virus but i verifed it was in the correct folder. im running win xp media center edition with sp3. while looking at processes in the task mgr the system idle process is usually at the top of the list. my computer pretty much freezes up every few seconds now for a second or 2 and whenever i open any program it freezes up for a good minute or 2. Anything else ya'll might need to know feel free to ask. is there a way i could check if it is a hardware problem? this is a Hp pavillion laptop amd turion 1.99ghz 2gb ram. i have also tweaked xp to run faster by removing the themes among other things. I think thats the only thing saving me right now.

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.

My laptop recently became extremely slow. The CPU usage is barely ever under 94-100% when any programs are running. I was wondering if you could help me find out what is wrong with it

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.

I'm running XP pro SP2. I have a gig of ram and my mother board is an Intel D101GGC. My CPU is Intel Pentium D 920.
If I use Windows Explorer to go deeper than the first level of any tree, CPU usage goes to 100% and stays there. I've disabled System Restore because it wouldn't let me go back in time anyway and this program is a known resource gobbler. Didn't help. I've attached a hijackthis logfile to see if anyone recognizes a Trojan, etc. I would appreciate any help at all.

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 recently kept getting a blue screen everytime I tried to restart my computer. This happened with my old computer and I ended up having to get a new Hard Drive. Well I was able to fix this problem by booting in safe mode and system restoring to an earlier date. Well now my CPU Usage is always running high, over 30% almost aways, dipping all the way up to 100% sometimes. This is when I have nothing system heavy running, I have Dual 3.2Ghz EE processors and 2GB of Ram.Well I was getting a similar problem last month, it was because of the trojan vundo. I got vundo off a couple weeks ago and no more CPU Usage problems. Well I didn't go THAT far back in system restore. So I did an updated Norton Scan, and updated Adaware scan and an updated spybot scan, still gettin the problem. It's doin enough that I cant watch videos with th epicture being jerky and sometimes it freezes my IE for 15 or so seconds.

I'm hoping I can resolve an issue here. First let me start out by apologizing for this long post, but i'm trying to get as much info out as I can.Recently i've been having big problems with my computer running VERY slow, my computer takes 5 minutes to boot up when normally it would only take 1, my mouse moves very laggy, and I can't start up any programs without having to wait minutes just for it to start. When I look at the performance monitor, my CPU usage is anywhere from 50%-100%...and i'm not even running anything! First let me get somet things out of the way. First off I have a laptop with AMD Athalog 64 2.5 ghz processor, 1.0gig of ram, and a ATI X600 mobility video card. I've had my computer for a little over a month so it's not outdated or anything, and all of my drivers are up to date.
I did a viruscan on my computer which took very long b/c my CPU usage was very high, and nothing negative came back when I did so. I ran adaware and removed all of the adware I had.still didn't fix the problem.
After trying both of those things I decided i'd try to restore my computer to an earlier point. it was successful. That was a couple days ago when I was having this same problem. Well here we are present date, and i'm having the same problem again. I tried restoring my computer to an earlier point again, but this time it resulted with some troublesome problems, apparently an important ATI file was deleted or something (not sure exactly) and I couldn't boot my computer up in normal mode, I had to go back into safe mode and rollback the drivers for my computer to even boot up. That was approximately 30 minutes ago, and here i am now. Obviously restoring didn't help this time because my computer is very slow at the moment.
I don't get it, because both times this has happened, it comes out of no where. My computer will be running just fine, then 'BAM!' out of no where my CPU usage is out of the roof. I'll try restarting, closing everything on my toolbar nothing works. Speaking of toolbars, mine is pretty empty, it's not overloaded with a bunch of crap, mostly just important stuff like firewall and virus scan. I can't imagine that restoring my computer is the only option here. There has to be something that is causing this, that i'm not detecting. Originally I would have guaranteed it was a virus, but McAfee Virusscan isn't picking up anything. And it's obviously some software issue, because when I tried restoring my computer a few days ago when I was having this problem, everything ended up working normally after that. This time when I tried it though, there was no luck.

My CPU Usage is too high. My computer is running really slow because of it. I looked under Windows Task Manager/Processes and System is taking up about 50% of the CPU Usage. It is not a virus because I have been through a whole thread in the Security section and they said I have no infection. This does this off and on. I have been having this problem for a while and then it stopped. I just restarted my computer and it just started again.

This question is actually going to be for a friend of mine mostly and secondly for me. We have the same issue.We both have Norton Antivirus 2007 and the latest updates We both Have Zone Alarm Pro and the latest updates We both have all the latest drivers for all our hardware and use third party driver toolkits just to be sure about it We both Recently formated and reinstalled windows and made sure we have all the latest windows updates We both scan for viruses and other types of malware religiously For some strange reason my computer will be completely idle and out of nowhere the CPU will start running high (fast).I mean, it's literally out of nowhere because there are no changes in whatever i am doing. I will leave the computer completely untouched, without being connected to the internet and the CPU will just go off on its own running at high speeds out of nowhere. I don't even have a screensaver.

this problem just happened today.. my cpu usage seems to spike to about 50% every 5-10 seconds, and it's become unbearable to work with.i scanned with avg and it detected nothing.. i believe the problem stems from something called services.exe because when i ctrl alt del, i can see in processes that it spikes up to a high amount of cpu usage. i did some googling and haven't found much help on the issue.

I formated my pc, deleted the partitions, recreated them and installed 2 OS of XP in each partition (same way and thing as I had b4). This time my cpu approaches 100% with nearly anything, from opening a window to scrolling down. Everything I do raises the cpu. The only thin I installed are the drivers for motherboard and antivirus. I checked the pc with 3 diff programs for viruses and nothing came up. I can do nothing! Plus I got this windows poping up telling me that I got system critical errors and that my registry is corrupted (?)

My computer started slowing dow about a month ago. It got to where it took forever to load when I turned the computer on and even opening software took forever. Same with turning it off. It also hangs up on me. I can't even press Ctrl + Alt+ Delete to end a program when its not responding. I have to strictly turn the computer off just to get somewhere. I uninstalled and reinstalled Norton. I have the entire Norton system and catches nothing. It says all systems are working properly.
I was asked earlier if I had ever put a music CD in the computer that was by SONY, and I can say that probably close to 20 over the 4 years that I have had it. I was told that SONY puts this "thing" on the CDs that transfer to your computer before you even hear the music so that you are penalized if you try to duplicate them.

Win Xp - Service Pack 2, I suspect the problem lays with a trojan dropper. In fact I'm certain. At the moment I am getting a trojan dropper putting random files into my temp internet files every 3-4 hours - the latest file being SQL.AVG?? Norton deletes it as soon as it appears but I'm certain its causing my 90-100% CPU usage on explorer. exe. Its been doing this for about the last week.
I've got all of these installed - ZoneAlarm, Norton, AVG 7.1, Ad-Aware Se and even Microsoft Anti-Virus. I updated them all and went into safe mode and ran every single one of them on full scan and none have found the culprit. When booted back into normal mode the trojan dropper has started again and cpu usage back up to 100% for explorer.exe. Basically everthing crawls after 5 or so minutes of reboot.

I'm running XP on a computer with 1.3 gig CPU, 768MB RAM and 60 gig HD. My CPU usage is typically about 25-40%, but if I want to link to a video clip online and run it, CPU usage goes to 100% and the video won't run.I had a bad browser hijacker in May which took 10 days to fix with Tech guy help and me learning along the way, and a small problem in August, again fixed through advice from TechGuy, which I really appreciated.However, I have another teen living with us now, who says that my CPU usage should only be about 5%.Could someone help me decide what I layers of protection I can do without or how to configure all the anti-everything software I have that was recommended in May? I look forward to hearing back from someone.

my computer has been running abnormally slow, and I don't mean 5-10 seconds for a program to load, more minutes. Once, it took, from turning the computer on, to arriving on desktop a total of 12 minutes, that was without half the stuff even loading by then!
The slow speed usually occurs when rebooting, I left my computer on for serveral days and eventually it worked good as ever.
I'm not sure if it matters, but soon before loading the desktop, there's a weird grinding type noise coming from the computer, this lasts for about 5-6 seconds, and happens several times.
