CPU Usage % / Two Files Occasionally Start Running And Tie Up Cpu Capacity
Mar 9, 2005
Two files occasionally start running which tie up large amounts of CPU capacity. Checking thro Task Manager these appear to be
MSMSG.EXE which i assume is microsoft messages of some form but no message is actally on screen the other is VSMON.exe which is part of the Zone lab firewall, they only activate sporadically and when I am on the Net but they show cpu usage at 80%+ so everything freezes. When they are not active the cpu runs at around 15%.

My computer is running at 100% full capacity all of the time. As you can imagine, this makes things run very slowly. Any ideas of what could be causing this problem? My task manager has unfortunately stopped showing processes, and no programs are running when the capacity shows 100% usage.
I'm using a dell inspiron 8000, Windows 2000, Pentium III.

here's what's up - after about 10 minutes of being on the computer it slows down significantly, particularly web browsing. i usually notice the problem when using firefox 2.0 to check out videos on Internet. after watching 2 or so videos, the videos become very choppy and the system starts coming to a halt. checking out the task manager - i find that the cpu hits 100% during these episodes and per the processes the cpu is being gobbled up by firefox. a similar thing happens when i run itunes.
i installed a browser to monitor cpu speed/temp etc. i found that i have tons of ram available (at least 600 mb) even during the slow periods. i also found that the cpu temp is pretty reasonable (53 c) but then i found that my cpu is running at 600 mhz (most of the time, irregardless if plugged in or not). i can't seem to make my system run at full cpu capacity and am not sure why or if this has anything to do with my problem.

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.

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

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.

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.

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 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

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 was helped by Flrman1 last weekend in getting rid of a trojan, and it worked great. Scans come up clean now. But since contracting it even up to today, my machine seems to be running sluggish. Even running a non-online game runs the CPU usage to 100%. Have I too many things running in the background, and how can I get rid of unnecessary stuff? I fear some things are running that I did not intentionally put on there.

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.

I have a Toshiba Satellite notebook (about 18 months to two years old) running XP Pro, and frequently I encounter a situation where, with no programs running, explorer.exe "cycles" in activity and CPU usage - for example, from 30,000 K Memory Usage to 50,000 K to 70,000 K to 90,000 K (over the course of 10 seconds or so), then drops back down to 30 or 40,000K and starts over.

I would really appreciate some advice concerning a troublesome computer.A friend who was running Windows XP on a two-years old computer began to experience occasional freezes and blue screens without any apparent pattern in program or usage. It eventually got so bad that we removed most of his installed software other than the essential, but problems continued. We then made a repair installation of Windows XP from the Dell OS installation disk, after which the computer would fall over every time after initial boot up. With sinking heart (of course, he had no image, but had data backups) we then formatted the hard disk and executed a fresh installation of Windows XP.
Windows now boots but the Windows directories contain very few folders or files. The CD drive can only be read perhaps 50% of the time. Most program installation files refuse to run, but some do. One installation disk which will not run is his internet installation. The computer continues to display sporadic blue screens.Before it goes out the window can anyone suggest our next course of enquiry?

Windows seem to have a REALLY big problem when it comes to reading AVI files. It seems that when you click on an AVI file in explorer, it'll try to read the entire AVI file to determine the width,height, etc. of the AVI file this is displayed in the Properties window. Now the problem with Windows is that if you have a broken/not fully downloaded AVI file that doesnt contain this info, Windows will scan the entire AVI file trying to figure out all these properties which in the process will probably cause 100% CPU usage and heavy memory usage.

I used my External Harddrive on a macintosh computer - no problem there. I just needed to copy some files from the ext. onto the mac - All Good...
Now my PC won't recognize the files on my ext. I have been reading support forums for the like, but I have not found a solution.
The Mac did not give me any warning that it was altering the file format or anything like that, but it apparently has.
Is there any way I can get my files recognized by my p.c.? Windows XP.

All the .html files on mywindows XP sp2 machine have been renamed to .htm and further when I try to rename them, the explorer CPU usage suddenly increases to maximum. But, some files gets renamed and others can't be renamed at all. And, for those which cannot be renamed, I get a pop-up error message saying "file is being used by another program and cannot be renamed.", and that's when explorer starts using all of CPU and system gets very slow.I have already done full system scan through Kaspersky and Malware Bytes Anti-Malware, but they have simple turned out to be futile.
