Can't find reason of 100% cpu usage

My computer freezes suddenly, using 100% cpu.

the problem occures in windows when surfin the internet etc or if i'm trying to run a game.

It happens in both Windows XP and Windows Vista :S

I have recently upgraded my computer with this hardware:

* AMD Athlon64 X2 6000+
* Asus M2N-X Plus mainboard
* Apacer 1024mb DDR2-800mhz (2x these running dual-channel)

This is my other hardware in the computer:

* NorthQ 400w PSU
* Samsung 250GB S-ATA
* WD 500GB S-ATA
* DVD-RW

I have tried this without any luck:

* Updated BIOS to newest version
* Tried another PSU (also 400w, but should be enough)
* Windows Update
* Updatet chipset drivers from Asus' webpages
* Installed AMD's cool&quiet driver
* Tried the ram one at a time
* Running memtest86+ on the ram in 9 hours without error
* Tried changing harddrives
* Reinstalled windows xp and vista multiple times
* Tried different display drivers (ati, omegadrivers and the one included in vista)

I Have checked the temperature and volt readings on the cpu.

Any tips what can be wrong, or how i can find out?

How many processes do you have running in Background. I do not know how you can check for Vista, but for XP, go to Run from the Start menu and type "msconfig". Then make sure Selective StartUp is selected and then go to tartUp tab on top.

What you will need to do is leave all MS stuff, graphic exe and AntiVirus/Firewall stuff. Apply, click OK and then Reboot. Once done rebooting you will see a popup screen about Slected StartUp, click on do not show. This should help with Starting up faster and also keep your resources free in the background.

Also you can restrict some proccesses from the Adminstrative Tools from your Control Panel. Below is a list of stuff you can disable and stop.

Automatic Updates
Windows Firewall
Windows Installer
Anything doing with Remote Connection, Workstation and Servers applications.

I do have a FX60 cpu that use to act like what your problem is. I have done what I put down here and my computer boots up faster and hardly uses 100% of resources any more. It seems that when AMD dual core cpu's start getting warm, they tend to use more of your computer resources. Also when this happens. do a Defrag of computer and if you have Ad-Adware SE spyware program, run it (since cooies do report back to owner of them).

Hope this helped you out some.

roadrunner: the temp was around 40 celsius, and the volts were like they should.. about 3.3, 5.0, 11.9

what do you mean by disable hardware accelleration?


yoosty: the selective startup would not be any use i guess, since i havent installed anything other than chipsetdrivers and display drivers. but i will try it anyway, thanks for the tips. the firewall and automatic updates are disabled.

If FireFox is using 50% that means is using an entire core. That may be your issue there.

how old is the processor? have you overclocked it and had a bad result lately?
try running the same programs in safe mode. does it cause the same error?

Device manager showing anything not installed properly?

Has firefox been updated?

Click on:

help>check for updates

That's an awful lot of usage going on there. I mean, I'm running firefox, and usage is 0. I started up winamp, playing music, and usuage is 0. But taskmanager shows 1-3 percent usage.

Not sure what is going on your system. Seems like its doing updates or trying.

We need clues from taskmanager. Are your Windows CD/DVD bootlegged? Some bootlegged media has built in viruses.

Does it do this after a fresh install or after a software install. Try running windows after a fresh install and let us know what happens. A software such as a antivirus or something might be the cause. If it does it with just windows then we have a much bigger unknown problem.

I'm at a loss for now.

If it is indeed software and it happens before you install anything, could it be something on your asus cd? Try running the system without using the ASUS cd and just download drivers from the net if you need any. Although Windows update should find your drivers if you need any.

you run windows, enough said.

Windows is not really a operating system. Its a system operator.

hahaha

Do you have onboard and a seperate card?

i have a pciex club3d radeon x1600xt...

the event viewer have errors like these:

i'm trying to download a older catalyst driver, and shall try that.

Please screenshot the processes tab with all processes showing, please organize by CPU usage first.

Thanks.

Cool I'd say you got it now get a new card.
