99% core utilization..whats wrong!!!!

[mgacam2]

alright so vista is running extremely slow, and games also run extremely slow. This includes simple games like maple story which dont even take advantage of 3d. I have the latest 158.8 forceware drivers for vista 32 bit installed and its slow, as well this is a fresh install and my computer is using 99% of one of the cores. The other cores jumps up and down from 1-4% like it should. What exactly is the matter? its not memory problems and iv reset my bios and such so anyone have any ideas. my pc specs are in my sig

First thing i thought of was maybe a virus or spyware?

There really isn't enough information here to offer much advice. Something clearly is pegging a core, open taskman and figure out what process it is (and if it's a service, which service it is). From there perhaps we can provide more guided advice.

Rockwell: Randomly guessing at vauge symptoms does no-one any good.

well its a fresh install no spyware and such, im really good at keeping with that, as well i turned off windows indexing and such, and i checked task manager, nothing is showing any apparent lag on the cpu. The thing is the day before that it was working perfectly fine. Then boom the next day it stopped working well. Im really going from a fresh install with all windows microsoft updates done. I turned off all things that could hog it down, but it doesnt explain how it WAS working well when i didnt even change anything.

You said that something is keeping one of the cores at 99%, if thats the case it WILL show in taskman, so please look again. Otherwise, I'm not sure where you are getting that 99% utilization number from...

my task manager processes barely peak over 1 but it says all together im doing around 48% useage 2% on 1 core and 99% on the other. It shows that in the performance tab of task manager

 

[mgacam2]

alright so i changed the process list and what it shows and it says its being used by System Idle Process I tried to end the process and it doesnt let me...its a system process

 

[mgacam2]

by the way i know that system idle process is exactly that left over power, but it doesnt explain why my computer runs so slow suddenly and especially games like simple 2d scrollers lagging. My athlon 700 with a geforce 2 could play it perfectly why cant a core2duo overclocked with a 7600gt do it like it did on xp

click the show processes from all users button.

 

[mgacam2]

i did that already, and like i said read above

 

[Noema]

I've had happen that to me; In my case it was a loose PCI card that was making XP behave funky.

Try reseating your video card and your RAM...it's worth a shot at any rate.

 

[mgacam2]

yeah i tried, it didnt work unfortunatly..iv even resorted to rebuilding my computer a few times except for taking the motherboard out...i did just get a new case.. do you think there is a possibility of a short on my motherboard that is causing this performance lag?

Not much more to do here, we've tried to help, and you've been at best 'diffcult' (e.g. answers like the above). If taskman is showing 100% utilization on one of the cores then one of your process list entries should be showing that usage The data comes from the same place.

How about this, post a picture of your process list while your having this issue.

The task manager CPU graph and task list don't show exactly the same things. It is possible for a CPU to be used but the usage not to show in the task list - this is most likely due to hardware causing excessive Windows kernel CPU usage (which doesn't show in the process list).

The best thing to do is to get hold of the 'processXP' system tool from microsoft (it's a free download). It will show you exactly what is using the CPU. When this happened to me - it showed the problem as 'hardware interrupts'. (Actually, just realised you are using vista - I suppose it's worth having a go with processXP, though i don't know whether it will actually run).

This immediately indentified the problem as a hardware one - I eventually traced it to a faulty USB cable (or some other trivial problem, but I can't quite remember). Anyway replacing the faulty item, solved the problem.

It will show, he's not pegging a core to 100% without something in that process list accounting for it. HW issues are extremely unlikely to effect a single core like this.

Um... yeah you don't want to end that and you can't.

Ok, good... that sounds like a driver issue though; did you install everything for the motherboard and video? Did they break somehow? Check the device manager for issues and maybe reinstall the drivers.

 

[mgacam2]

as i said i installed the newest forceware 158.18 nvidia drivers and my motherboard drivers are up to date. The only thing that has not been updated is my onboard sound driver, which i attemped to upgrade but it failed miserably due to poor vista support for it right now
