When asking the computer to do more than one task the CPU usage jumps up to 100% & slows down everything. This is particularly annoying when playing music or a video in Winamp or Media Player & then, for example, connecting to the net or even opening a 1KB document, because everything freezes up for 30 seconds until the "new" task has finally opened. I've got a program that shows about 80% "Hardware Interrupts" going on while the new application is opening. I've been trying to fix it for 2 months with no success. There are no baddies on the computer for definite. The task manager shows as 100% CPU usage until the new application, (whatever it may be), opens. There are no conflicts with any drivers & everything is working fine on the computer & is really fast at everything, until i ask it to do more than one thing at the same time. Using Windows XP with Athlon AMD computer. :eek: Please help, coz it's doing my head in.

Hello,

A Hardware Interrupt is a "message" that the hardware will give the CPU saying that attention is needed somewhere else. For example, if your CPU is adding some numbers together, and something comes in on the serial port (such as a modem connection), the port will send an interrupt to the CPU, and ask it to read the data sitting in the buffer. Keyboards, mice, even the video cards have interrupts.

I think that you have an OS issue, as it is happening globally, and you are losing the battle with it. Because you mention that your computer is quite fast running one program, I am going to believe your hardware and RAM are alright.

If I were you, I would save off my data, and re-install from ground zero. As complex as windows is, you could spend the better part of another month trying to find it. Start clean.

Thanks K.C. for that. I've uninstalled just about everything from the computer, loads & loads of software & all external hardware, to try and isolate & detect the cause. It's still the same! I'm not an expert with computers & can get "stuck" on what would be a simple thing for a person "in the know". I'm going to try two more things before i wipe the thing clean & start from scratch & hope you can advise me. 1. I tried to uninstall Outlook Express yesterday & with all the warnings it gave me, i declined. Would it be ok. to uninstall Outlook Express? 2. I have the Motherboard Utilities CD with a service pack for all the drivers & other things i don't understand. How do i go about uninstalling drivers, then reinstalling them from the disk? Do i delete ALL DRIVERS from Device Manager then put in the disk, do i have to boot from the disk or just bang it in? There have been trojans, dialers, viruses, worms, adware & spyware detected & completely removed a couple of months ago & the puter is completely cured from "baddies", but just wondering if this has resulted in damage or corrupt drivers or whatever? One more clue........the "sound manager" icon on the task-bar appears & disappears at will, the "start-up" sound is scratchy too. When asking the puter to do 2 things at once its as slow as a pack horse, but then if i close both things then do them again, then everythings normal & low CPU usage. Then, for example, if i then open 2 entirely different programs then it takes 1 minute for the 2nd program to open with hardware interrupts & 100% CPU usage. Yet, close these programs & then open them again (& it doesn't have to be EXACTLY the same things, just similar, within the same applications), then evrything is lightening fast & about 7% CPU usage. Then, if i went back to the original 2 programs it now seems as though the puter has forgotten how to open 2 programs it opened 2 mins earlier, & it's so slow at responding (the 1st time) that i get the "send error" report, this program is not responding etc. Thanks again K.C.

Hope this gives some clues to a good Samaritan.

I noticed that you have Norton, which is a good start, but I suggest you also get Spybot S&D ( http://www.safer-networking.org )

Hello Megahertz, i already got rid of all of the above & just about everything else last month, & the problem still remained. It's gonna be a simple solution this one.

Just to re-iterate what's happening. If i open up ANYTHING, everything's OK. It's when the puter then opens ANYTHING else, ie, with the 1st program still opened, that the putergoes to 100% & all this hardware interrupts business & things take forever to open. Yet, if i close both programs, then open them up again (even if i do this 2 hours later), then everythings lightening fast & back to normal. But, then if i open 2 entirely different applications or one of the two above, with a new thing, then its back to square one! Once i've run loads & loads of programs in lots of different "combinations", then the puter is fine. It seems to "remember" where it's been & is OK then. Yet, ask it to do something it aint done yet on a particular session & it sort of works it out as if its in shock the 1st time.

I've just reinstalled windows by accident! When the puter started it flashed up this........"press any key to boot from disk", so i pressed a key. One hour later i have a fresh installation of windows PLUS the old one with everything still intact. All i wanted to do was chose a REPAIR option that someone told me about. Can anyone tell me how to get to the repair option on the windows installation disk?

After i did the above, on boot-up i noticed there were 2 options to chose how windows is gonna boot up. These were 2 choices of Windows XP Home Edition. The top choice brought me to the new installation & welcome/tour screen & the bottom choice took me to the original. When i went to the original settings & desktop etc, i noticed that some song tracks had changed their symbol to that of a file & would not play...(unrecognised file format). Most of them played OK in Winamp & Media Player, then suddenly, Media Player would not work at all. All i got when clicking on a song was an error "PING", but with no error message. The same happened if trying to open Media Player itself. I thought, "ney, i'm not having this", so did a SYSTEM RESTORE to the previous day & everything was OK again, (apart from the usual problem at start of this thread). So now, when starting the puter, i no longer get a choice of booting up to the new Windows installation, (probably due to the fact i've done System Restore). Shame really, because i was going to go to that & copy a folder called SOUND MANAGER from there & put it into our usual working "setup" because the folder (Sound Manager) is EMPTY.
Can anyone please tell me how to find this folder from the installation disk, without having to reinstall the whole lot.
So because i did system restore i would have thought that the new installation of windows would have now disappeared, well it's disappeared from the start up options for sure. Thing is, looking at the amount of space used up on the hard drive, it's stayed on EXACTLY the same mark as it was after doing the fresh installation of Windows yesterday, i'm 100% sure of this. How can this be possible?

I've now got "2" puters___________________with one "hidden"

Gosh!

You will probably need to do a proper windows update for your newly installed XP Home. The slow startup of applications sounds like a problem prior to SP1 installation.

Also you'll need to clean up those spywares on your system.


Go to :-
http://www.download.com/3000-8022-10122137.html

Download it, update it and do a scan on your system.

If you need to remove some persistent ones on your system, try tapping on F8 when your XP starts and select Safe Mode from the options.

Once in safe mode, run regedit (Start, Run, type regedit in box) and remove suspicious entries from :

1. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
2. HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Then restart and do a spyware scan again.

Can be quite a pain to remove these spywares but after that, you system will run faster and less random problems.

Also patch up your Internet Explorer. Alot of automatic installation of spywares are due to a unpatched IE. Or just use Firefox at mozilla.org.

Thanks Techahbeng. I'm going to look into these things you suggested apart from removing the spyware as these are reliant on other programs that we enjoy a lot & if the spyware is removed, the programs shut down or don't work correctly.

Last month i removed all traces of spy & adware & their related software, got everything up to date & scanned for everything bad. The puter was clean but the problem remained. So i've put all the brill things back on again.

The fav is going to be driver problems, conflicts, or the processor.

I installed an up-to-date soundcard driver yesterday & got all the features back that we used to have. Trouble is, the sound was terrible & the mp3 vids hardly played at all & the puter was as slow as it has ever been. (there is 61% of the hard drive still free). The updated driver was definitely the righjt one. I just put the damaged old driver back on & we are now back to as it was at the beginning of this thread.

I'm going to do a system restore point & install ALL drivers & update them too. There is a basic thing that i don't know! That is, i install all drivers into c:\temp THEN do i just install the new drivers over the existing ones? OR uninstall all the existing ones first?
I've been reading up & it says that some of the drivers are to be used ONLY with Direct X, 4.0, or Direct X 8.0, & this, that & the other. Recently i downloaded Direct X 9.0 (only because everywhere i went on the net, it said that we should)!

The manufacturers driver disk i have seems to be already obsolete & it's only 6 months old & the puter itself.

Could you please tell me the best way to install all the drivers. Finding them & installing them into temp (before unzipping) is not a problem at all. It's just what to do with the existing ones 1st. If i uninstall the existing drivers 1st then i won't be able to roll them back, is that right?
Cheers!
