High CPU usage all the time, even after format

[tal_be]

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.

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.

I'm at a loss as to what is causing it if you've updated drivers and BIOS.. What is the model of your mobo?

 

[tal_be]

My mobo is Gigabyte p35-s3l

Yes I ran an AV, and as I said, I've formatted my PC and didn't install anything after.

I've the same problem... my computer is barely 2 months old and its already thinking crazy... CPU is all the time 70-98%

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.

you run memtest yet?

I run AVZ, and looked into the LOG file, and there is nothing I can point as the problem's cause.

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

Open up start menu and type "system information" and click on that. Expand "components" and click on "problem devices". Read to me what it says...

When I click on problem devices, there are nothing written in the right side.

At the botton of this screenshot in the tray there's a flag with a "red X" open that... What is windows telling you?

Open up Action Center and turn off messages for Windows BU and firewall.

 

[tal_be]

Yes, I know to do that, but it's not the solution to my problems.

Has to be drivers...

you did re-install windows right?

 

[tal_be]

Yes, I re-installed windows, and already downloaded the drivers from your link.

Open start, computer, C:, program files and look for a "windows.old" folder. If it's not in program files try (X86)...

 

[tal_be]

I didn't find this file (Even if it's hidden)

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.
