Hello everyone,
For 2 months my computer made a lot of noise, and 2 days ago I decided to open it, remove all the hardware and check the source for the noise.
After I finished, I started the computer, and I've noticed that the computer is very slow, and the cpu usage is
always between 35%-90% when there are nothing open.
I've looked for spyware etc, and there were nothing.
I've decided to format my computer, and even now after the formatting, the cpu usage is high like before, and even in safe mode.
I haven't installed anything yet, and I think that there is an hardware problem and I need to replace my cpu and motherboard (core 2 due). I checked the hardware and cleaned the cpu fan, and it's the same.
What do you think the problem is?
Thanks, Tal.

Could you post a list of your hardware?
Make sure you have all of the best drivers for your hardware because windows doesn't always install the right drivers without help from it's user.
If your replace your motherboard/CPU you should (almost certainly need to) replace your RAM. You might also want to replace the hard drive.
You might want to hold off on new parts at least until AMD bulldozer comes out, if not Sandy bridge E or Ivy bridge. even if you don't want one of those CPUs they should lower the prices of current CPUs to make the wait worth your time.

as everybody suggest ... open your task manager first and see what happens there. If you find a process that eating your CPU resource, and there u go ... you know your problem. However if you can't find any processes which use your CPU resource .... it's time to download "Process Explorer" from Microsoft and I'm pretty sure that you will be able to see anything that eat up your CPU resource.
This happened to me a long time ago, and Task Exp could not find anything, and Process Explorer let me know that one IRQ was holding out my CPU and after much checking from Google I found out that IRQ belongs to HDD. So I change the SATA port from SATA0 to SATA1 and it worked (it means ... I must say goodbye to my SATA0 port T_T)

My HDD is good too, no error, but the problem with mine is the SATA port on my MB. So has to unplug it and plug it to another SATA port on my MB. So sometime you can't just rely on SMART information hehehe.
did you get the interrupt number (IRQ number)? if yes, try googling it to find out which hardware that cause that high CPU.

I tried to connect to another SATA port, and it's the same.
How can I get the IRQ number?
CPU temps are 63C(core 1) and 60C(core 2)

Reopen your case and check the wiring, looks like something is wrongly connected to the Mboard.Everything is connected.

I've updated all the drivers, and the bios, but the problem isn't passed.Yesterday I took out the bios battery, and after 2 minutes I returned it, and the cpu was fine, but now I turned on the pc, and the problem showed up again.
What to do? Maybe I have to replace my MB and cpu?
have you looked into the link that I gave you? You will be able to find the culprit behind your high CPU usage and act accordingly. Don't just change your CPU and MB ...... yes, that would be the easiest way, but .... the most expensive.

Ok people, step back a second:
1: PC was slow AFTER everything was physically removed, which points to a hardware problem
2: Item that is eating up time in Task Manager is "Hardware services and Interrupts", which again, points to hardware.
Now, could be a BIOS thing [due to hardware being removed], but more then likely, something either got damaged, or was not set up properly. I'd reset the BIOS back to defaults. Failing that, I would physcially remove everything again.

yes, you're right, it is hardware problem, but using process explorer and the method explained in the link I gave was to isolate which hardware that has problem. I use that method to find mine and It worked for me. :-)

I made reset to the BIOS battery, and the computer was fine after that.
I shutted down the computer, and the next day I turned it on, the problem came back.
I made the guide which "hasappra" recommended, and this is the result:

I've installed driver genius, and installed everything, but it's still the same.
I don't know what to do, please help me.

Hi Tal, sorry for my late reply. I saw the screenshot you posted .... and unfortunately I can't offer any help anymore since the one that brought your CPU up is actually "Unknown". You probably need to join that MSFN.org and ask for their help.
Oh, one thing, you probably need to see the detail from ntoskrnl.exe by clicking the (+) button and see what kind of process that holding your kernel.
If you don't want to join their Forum ... here is my suggestion ... since it is hardware problem. Usually it was because IRQ conflicts (you can check your IRQ using "system information") or damaged Hardware. So if I were you, I will try to disable my hardwares 1 by 1. For example: turn off your LAN (by disabling the driver in hardware management), then see. If the problem persist, you can disable another hardware Wifi for example, Modem, USB ports, sound card and so on. And if you have a onboard VGA, try to pull out your discrete VGA and using Onboard VGA to see whether your VGA was damaged or not. Pull out any added Hardware in your PCI slot or so on. Remember ... do it one by one so you can observe which hardware that caused your problem.

I have already tried to replace my hardware one by one, but when I replace the HDD the computer does a blue screen, and the the same with the graphic card.
The ironic thing, is that when I wrote the last reply, my computer was fine, and I shutted it down, and now when I turned it on, the problem is back.

Yes I ran an AV, and as I said, I've formatted my PC and didn't install anything after.Common mis-conception of people thinking if they re-install OS solves virus issues. Newer versions of adware have become resistant to formats or even detection of some of the better known AV programs. I'm not saying this is your issue but it is worth a gander. Download and run the AVZ script, you could be surprised.

And yes, I run memtest, there are no errors.

Ok, I want to update you about the problem:
I replaced my HDD with another, and also my video card with another. The computer didn't start so I had to took out the BIOS battery, and put it back.
I formatted the HDD, and installed windows, and the CPU was good.
I took out the Video card, and put mine, and the cpu was good again.
I took out the HDD, and put mine, and the CPU was good again!
So, I think the problem is related to the bios battery/motherboard, because the last time I reported that the cpu was ok, was after I took out the bios battery, and the next day the problem was back.
So, what do you recommend me to do? to replace my mobo?
(I've already updated the bios...).

I don't think it's the board or cpu... but if you're loooking for a reason then go ahead.
Have your checked your HDD for errors? Open start, computer, right click C:, properties, tools, check now and reboot. Takes a little while but windows is pretty effective.
You could open up device manager and start disabling things like network adapters until you find the culprit...

I run the test, nothing was found.
I dont think that there is a problem with my HDD, because now after restarting the bios, i'm working with my hdd, and the cpu is good.
