Explorer/ High CPU Usage / CPU Usage Goes To 100% And Stays There

Apr 6, 2007

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.

High CPU Usage On Explorer.exe

Apr 29, 2006

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.

Unusually High Memory Usage By Explorer.exe And Svchost.exe

Explorer.exe-high Cpu Usage / Invalid Time Stamp

Jun 1, 2005

I'm having a problem when i start up my comp. after logging into my user account, the monitor sorta "blinks" periodically.. as in, the wallpaper is there, but all the icons disappear. However, as soon as i open Norton Antivirus , the problem stopped (until the next time i restart the computer and log on).

On loggin in, I checked the cpu usage with taskmgr, and foud that it was goin pretty high (jumping frm 10%to 60% or 80%).. when i checked out the running processes, "EXPLORER.EXE" was taking up around 95% or so.

Explorer High CPU Usage 2 / Wont Open A Signal Folder

Feb 6, 2004

My explorer has gone nuts. It will run programs, run shortcuts to anything but folders and the real problem is that it wont open a signal folder either by explore or open commands. I've reinstalled WINXP off the CD as update, nothing happened. I've ran the steps listed in the last forum. Nothing has worked. I'm desperate. I'm running WinXP Professional on a basically 7 month old Dell comp with 512RAM and a 2.4 GhZ Pentium in it. I'm lost at what to do.

CPU Usage Always High?

Oct 31, 2005

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.

CPU Usage VERY High

Feb 10, 2006

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.

CPU Usage Is Too High

May 22, 2006

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.

What To Do About High CPU Usage?

Jan 2, 2007

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.

Very High Cpu Usage

Nov 23, 2007

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.

High CPU Usage With Everything

Sep 16, 2006

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 (?)

Running XP / CPU Usage Is Too High

Oct 10, 2006

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.

High Cpu Usage On New System - New Installation

Jan 6, 2006

My new system has an unusually high level of cpu usage after startup. Windows was only installed a week ago and I haven't installed much software on this yet. Today was the first day I got it online and all I did was install the newest windows updates. The only things I've installed in it are nero, omega radeon drivers, videolan media player, winamp, and adobe.I've looked at the hijack log and I don't see anything out of the ordinary. The odd thing is, the cpu usage isn't constant, it ranges from 30%-50% even when nothing is running.

Svchost.exe High Memory Usage

Apr 16, 2008

I have recently become annoyed at the high memory usage of the svchost.exe process. I have 8 of these services running at the moment. I havent had reason to complain until recently when they seem to be using more memory than necessary. I might just be over reacting here but perhaps someone can verify it for me. I have included a hijackthis log at the bottom.my system is running WindowsXP SP2, Asus K8VSE deluxe, Athlon 64 3200, 1.75 GB RAM, updated via drivers and windows updates (except one that just came in and I havent done yet).These just seem like too much memory for these. I have check at blackviper and didnt really see a lot of things I could turn off. I could be wrong though.

High Cpu Usage - Hangs Around 55% - Constantly

Jul 4, 2006

I recently have been seeing odd spikes in my cpu usage, and it hangs around 55% now constantly, occasionally peaking at 100. Also when I used EasyInfo (a system info utility that comes with EA games) it said my CPU speed was -1541 Mhz, even though I have a 2.8 Ghz Pentium IV. I installed Windows SP 2 a couple days a
Equally confusing is one other thing: I have installed Directx 9.0c but it does not say so on system info.

CPU Usage Running Extremely High

CPU Usage High / Unlisted Program?

Jan 2, 2007

I am using a P4 2.8ghz system with 512 RAM and Windows XP SP2.I do run a secure computer (AVG on and updated, Zone Alarm, Spybot's Tea Timer, Win Patrol, AdAware & Spybot run regularly, occasionally I double check things at PandaScan online).I am on a DSL connection behind a router. Never had any revealed spyware or virus problems (other than tracking cookies).At times my CPU usage shoots up to a high percentage (90 - 100%, occasionally dropping slightly) and remains there indefinitely. Here is the puzzling part - when I check the list of processes (sorted by CPU) the only number over 5% is System Idle Process. In other words the sorted list will have System Idle Process using 90% or more (which should be "unused") but at the same time the CPU Usage at the bottom is at or near 100%. How can this happen? Can there be a hidden program using CPU time? Could it be a rootkit? Hardware problem?

This has been very hard to diagnose because while it shows up regularly, it does not show up all the time. I have thought it solved several times only to have it show up again. Here are what might be related factors.It most often happens shortly after booting up. Within a minute or less of the last programs loading CPU spikes and remains high.If I quickly "Engage Internet lock" (in Zone Alarm) just after booting it does NOT occur. Even if I un-engage the internet lock just a minute later.It does not always happen after boot-up. This is frustrating because I have tried disabling some startup programs (Skype, IP Phone Center (works with Skype and a cordless phone), TeaTimer) and thought the problem was resolved only to have it occur again later.It will occasionally occur at some random point during use (or non-use). When it does this it sometimes will only run up to 60-70% CPU and remain there (again with nothing other than System Idle Process over 5%).

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.

Getting High Usage At Startup And Starting Programs?

Oct 28, 2007

Whenever I startup, the computer usage runs way up to 80-100% and it takes forever to start a program. It immidiately starts this whenever I just turn the computer on, and I hear it because the sound that Windows makes at startup gets scratchy and stutters. Once it has started up, if I click on iTunes (for example), once the program pops up and I click on Play, every song stutters. It stutters only at the beginning and then it smooths out, but it does it for every single song played.

High Cpu Usage, Extremely Choppy Sound And Video

Dec 22, 2008

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.

High Memory Usage For Svchost+wuauclt; USB Hubs Don't Work?

Sep 2, 2010

Both svchost.exe + wuauclt.exe's memory usage occassionally increases rapidly even if my laptop is idle. I have to terminate wuauclt.exe manually (through End Process in Task Manager) in order for the 'Commit Charge' to return to late 300/early 400M figures. If my 'Commit Charge' is 5XXM or above, if I plug any USB devices Windows XP won't recognise them. I have to terminate memory consuming programs (e.g. Firefox), restoring the Commit Charge to 4XXM, then Windows XP will recognised any USB devices I plug in. However, if I plug any USB devices right at the beginning when I turn on the laptop, I won't encounter any problems. Why is this?
