CPU 100%

by indrapest / October 19, 2009 12:06 PM PDT

Hello I've recently been given a computer from my father, and have been having this problem since I began using it.

After booting the machines fine until I open pretty much any application as this causes the CPU use to jump unaccountably to very high usually capping at 100% and staying there. What's interesting is that if say I'm using my web browser the CPU will decrease to something normal say until I refresh the page or another example if I leave a song on in media player it will calm down about 20% but jump again when I change the song.

The effect of all this is that I cant run more then a couple of programs at anyone time and even then if one maxes out the CPU all the others freeze. Larger programs like games wont run at-all.

This is not limited to any programs in particular anything that's 'moving' on the system causes the CPU to increase dramatically. even if the program is doing relatively nothing. (eg. This browser window is the only thing running on the pc at the momant and I'm at 100%)

Umm sorry if that's colluded -I have been trawling forums for similar problems but couldn't find any solutions that have worked.
Its defiantly each individual program that's running up the cpu so high

Its not for example explorer.exe or svchost.exe that's sapping it.

Shouldn't be the system: intel celeron 2.80 ghz cpu 1.96 gig ram
Running XP pro service pack 3
scanned with:
PC tools
Spyware doctor
registry mechanic

Doesn't seem that it could be a virus/worm It seemed that it could be a registry or driver error of some sort I just don't know where to go from here.

Thank you very much in advance for any help/ideas concerning this problem - (and for reading my long winded description).

little different problem
by pc browser / October 19, 2009 10:09 PM PDT
In reply to: CPU 100%

I had little different problem. I was fixing one of my client computer that indicate cpu 100% cpu usage, but in this case process called ?SYSTEM? showed 100% instead of ?system ideal? process. I found out it was a file usbport.sys causing the problem. I did temp fix by disabling all usb on device manager, and start working on solution to fix the problem. Maybe you should try to disable some device and narrow your problem. Not saying that it is hardware problem but it could be related. One other way I checked to make sure if it was hardware related and not software is to use spare hard drive and load operating system and see if it did same thing on freshly installed operating system.

Had same problem.

In reply to: CPU 100%

I spent month's trying to figure out my problem. This is a long shot but my problem was directly related to itunes. randomly uninstalled it one day after a couple months of weird cpu usage and such even when itunes wasn't running. uninstalled it and bam everything was fine again. I've since reinstalled it and all is good. wierd I know but it was definately itunes or a related component of itunes that was my problem for month's with no signs of it being the problem till the instant i uninstalled it!

while searching for my issue I also heard of usb related issues causing this type of problem. try disconnecting all the device's, see if that changes anything. and by all I mean all if its a desktop even front usb ports and stuff, unistall those devices in device manager, if it works plug back in one by one till the problem comes back. then u know which one it is.

Thanks guys

In reply to: Had same problem.

Don't currently have iTunes on this pc but it has been on here before so if I run out of options later I will start to check it was un-installed properly but thank-you that was definatly worth a try (especially as it took two minutes)

As for hardware I will definatly start trying to eliminate some items from the device manager, But I was wondering if I could get some help interpreting there older fix's/responses that I've found:

*"Then i UNINSTALLED all the primary and secondary ide CONTROLLERS in device manager,rebooted,it found all 3 HDs again reinstalled the controllers,rebooted and bobs your uncle i now have a computer that is extremely happy,running no problems"*

*"Problem solved!
It turned out that I had a heck of a problem with Hardware Interrupts. They were what was shooting my CPU Usage up.
I ended up going into the Device Manager, looking at my Primary IDE Monitor, seeing it was left in PIO, uninstalling it, restarting, and PRESTO! Fast computer again!*"

...Did Both these guys reinstall their hard-drives? whats a primary IDE monitor? Im hoping this could be the answer because both of their original questions mirror my problem.

And so if I reinstall my hard-drive -Only have 1 (segmented)
Will I end up formatting it? Do I have a secondary controller as I only have the one drive? and if I uninstall it through the device manager wont the system crash as I booted from that drive? ..Do I do it through the bios maybe?

Much thanks again.

No they are not

In reply to: Thanks guys

They are not adding or removing hard drive they are just uninstalling the driver for controller and reinstalling. When you go to device manager, you will see those listed under IDE controller. You can right click and uninstalled. reboot your pc and it should find the device and load driver itself.

In reply to: No they are not

What would my next course of action be if for some reason it could not find the driver, where will I be left -will the system boot or will I be left in the bios :/

Is it just highly unlikely that they wont be found?

I really wont to do it right now but there are some applications backed up of my dads on here so I have to be a little cautious.

Thanks again.

In reply to: should?

Primary IDE channel & Secondary IDE channel both seem normal drivers dating back to 2001 but I also have...

SiS 5513 IDE UDMA controller.. now whats this guy?
In its properties it has a device property tab which contains information for the hard-drive x2 [channel1] (I'm sure its just a partition) and also the two cd drives [channel two]

Is this in some way managing the drives, do I need this? should I uninstall this one first? looks to me like one of those 3rd party drivers then tells you things you could already find out in slightly more easily available colourful way... Can I kill it.. please

Thank-you again

hardware controller
by Porch-a-Geese / October 20, 2009 12:44 PM PDT
In reply to: I'll just add:

That is what you have there.
You need to see what services are running while the usage spikes.
Turn them off if possible.
If you don't need any messenger or music services, turn them off also.
Pick one antivirus/firewall and run that.
People- especially the moderators- on this forum get tired of my same advice; but, securing your computer at the start cuts down on a lot of trouble.

In reply to: hardware controller

You mean I should find that program that tells you what svchost.exe are being used by?

I don't think this fix I was trying worked I reinstalled the and primary & secondary & the hardware controller and the problem is unchanged except now the cd drives don't work **Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. (Code 38)**?

Yeah I appreciate the frustration of repeated advice but assure you I've tried to avoid that by reading every old related thread on the net I could find

I the problem still occurs with every process turned off that the system will allow without crashing. I've never used more then one AV and this machines has always been secured with the pc tools suite. which is what let us too hardware.

Once I fix these these cd drives ill continue to try and eliminate hardware from the device manager.

I was wonder if maybe the CPU is just on its last legs or this has something to do with integrated graphics? Seems very strange that I can run all manor of programs in the background and they will return to an expected level of cpu use, but when I alt-tab to 'process explorer' for example the cpu use for that application in particular hits 100%...why is it happy to run anything until I alt-tab to it..

Thank-you again for any help/advice if I get to the bottom of this I will definatly post the fix

Just had to mention here.. as part of what I was doing I ended updating the display adapter and oh my goodness what a difference its like a different computer its really amazing -and not something I would have done otherwise.(this is of course in the intervals when my CPU isn't jammed at a 100%)

If you can get a disk and burn it- image not data- and it boots and runs, then maybe you need software for your local OS.

Thank-you for the cd drive advice I have them working again now.

In answer to "what is taking up so much cpu' its whatever application I'm using at the time -as I'm typing this text its staggering because my web browser is at 94% however If I for eg. alt-tab to media player my web browser will return to normal (0-3%) and media players cpu use will spike to the high 90's(or 100 if there is nothing else using any cpu.)

Which is what I was trying to explain I found weird before I can run many programs and they would all be fine except what ever I have open in the for-ground smashes the cpu and freezes everything.

Tweak the browser
by Porch-a-Geese / October 20, 2009 5:02 PM PDT
In reply to: -

Whichever you are using, make it more secure.
There are tutorials for memory limiting in Firefox.
With IE, I'd say make it like a box and only allow very few sites access.
For the other- and I stopped to look again- my girlfriend's computer ahs the same type of processor with i810. Celeron D.
It also has issues with performance- which is one reason I installed Debian on it.
If the desktop and gui requires a lot of background processes to be run, it will kill performance.
Do you have a pci(e/x/2/16) or agp slot for a graphics card and a graphics card? the install it, that will help performance.
A pci(?) sound card available? Install that also.
These two will help cut down on cpu usage.
You may have multiple instances running in the background. Cut them down.

In reply to: Tweak the browser

that's a good pion't I will tweak my browser.

and would definatly look at getting some more grunt but this has a 2.8gighz processor It should be able to run paint without taking paint.exe up to 100% cpu-

(And yea I tried running nothing in the background basically had it down to svchost.exe(s) and explorer.exe and the problem was unaffected...its amazing what runs under svchost.exe actually WinPatrol gives you a list but I'm in 2 minds as to whether thats where the problem could be.)

-and indeed it does run very nicely in the 5 seconds before the cpu realises I've opened paint (for eg.) and devotes all its spare energy towards it crashing it at 100%cpu

It's almost as if its homing onto whatever I'm doing like I said before if I want I can run huge games in the background but it will spike the process of whatever I'm doing in the foreground no matter how measily

It's started actually crashing as I've been experimentally running larger applications, It just reboots, doesn't go2 blue screen just restarts itself basically.

I told my dad this (whom I just inherited the PC from ..if you'v been reading the novel that is this thread) And he said it has actually been doing this for some time.

:/ Theres got to be something going on here.. Maybe the motherboard was just never quite installed properly? I've tried eliminating hardware done the IDE controllers which seem to have been the problem for others in this situation

It's so frustrating because this would be an excellent PC especially as I had no chance of affording one.. It even has a nice large flat screen monitor Happy If only I could sort out this problem.

..actually going back to the instances where removing/reinstalling the IDE controllers worked I believe massive hardware interrupts were involved and whilst process explorers tells me I occasionly have 10-20%cpu interrupts its the program that i'm actually using (regardless of what running in the backround) that gets spiked... so im very confused..

Thanks again for all help/ideas that have been offered for this issue it is greatly appreciated.

How does a Linux liveCD run on the machine you have?

I'm talking about performance. go to mirrors and what you want is version 5.
Burn the image.
hit the k
go to control panel, peripherals, keyboard, and set repeat rate to 10/s .
hit number lock.
everything is single click.
firefox is iceweasel in networking.

I will be told that I'm trying to hack a product by a few of the moderators.
If the livecd works then your system may be salvageable but not with windows.

Be sure that the BIOS can boot from the cdrom.
Whatever CD burning suite you have, look up the instructions to burn an image to disc- iso format. The last time I had windows, I used both roxio and nero. There's a program in the advanced menus for doing so. in English for you. sample directory.

ADRIANE is not what you will need. Version 5.X. KNOPPIX_V5.1.1CD-2007-01-04-EN.iso

Hard drive?

In reply to: cool

can you run any test's on the hard drive? I know this sounds wierd again but I had a friend a couple years ago with the same problem and his hard drive was done. took him 3 month's to diagnose it it would hang all the time on any app run at 100% everything still worked just really wierd cpu usage and stuff and like I said hanging loading app's and what not. anything that required hd access. i forgot about it till yesterday. I don't know, its just one more thing to try. if you can get a read/write test to run that is? but your right. this isn't windows vista running crysis. this is basic computing task's and you should'nt need to be limiting stuff in app's thats just nonsense. seriously check the hd.

When I had this EXACT same issue it ended up being that my sound card was plugged in to a bad PCI slot. I plugged it into a different one and it fixed it right away.

by indrapest / October 23, 2009 1:53 PM PDT

now we're talking that really does seem to be the basis of my problem, that's 2 sets of really good advice actually I'll move the sound and tv card to different slots.

..And I'd checked the IDE controllers but hadn't looked any further into the hard-drive being the culprit. I don't know of anything that could scan the hard-drive for errors like that? If anyone does that would be a really useful resource? Happy

As far as XP goes it seems to think its fine and I've done a defrag & checked the disk for errors.

What I'll do is install windows onto the other hard-drive in the tower and boot off that -I've tried booting the pc with that hard-drive deactivated before so I'm fairly sure the problem couldn't be that one although it is older.

Thanks again for all comments and ideas related to this issue, I had just about given-up.
