I just removed maleware on the maleware forum and and it was suggested I post a topic on the hardware forum. I still have a hight cpu usage. Lowest svchost service is 50% and most of the time 100%. From process explorer the svchost program is running Esent.dll and I have 40 entries of this line

DataStore.edb C:\Windows\SoftwareDistribution\DataStore\DataStore.edb

OK, let's try something....

Go Start>Run (Start Search in Vista), type in:
msconfig
Click OK (hit Enter in Vista).

Click on Startup tab.
Click Disable all
IMPORTANT! In case of laptop, make sure, you do NOT disable any keyboard, or touchpad entries.

Click Services tab.
Put checkmark in Hide all Microsoft services
Click Disable all.

IMPORTANT! Disable also Microsoft Security Essentials

Click OK.
Restart computer in Normal Mode.

NOTE. If you use different firewall, than Windows firewall, turn Windows firewall on, just for this test, since your regular firewall won't be running.
If you use Windows firewall, you're fine.

Post new PE log.

Oh boy. It's even worse.
Two svchost.exe processes are using almost 100% of your CPU.

However, you didn't disable Microsoft Security Essentials, which would be MsMpEng.exe process.
Disable it, restart computer and post new PE log.

Nothing helps.
Please, re-enable all items you just disabled and restart computer.
Those settings were for testing purposes only.

Basically, we have three possibilities:
- corrupted Windows profile
- corrupted Windows installation
- some hardware problem(s)

1. Create new Windows profile, boot to it and see how CPU usage is there.

2. Go Start>Run ("Start Search" in Vista/7), type in:
sfc /scannow
Click OK (hold CTRL, and SHIFT, hit Enter in Vista/7).
Have Windows CD/DVD handy (with Vista/7, most likely, you won't need it).
If System File Checker (sfc) will find any errors, it may ask you for the CD/DVD (rarely in Vista/7 case).

I created a new profile and performance was the same. I ran the sfc program and no files were replaced.

Download System Information for Windows (SIW free version)
No installation required.

After it scans your computer, navigate to Hardware>Sensors and post all info from there.

Aha, we're getting somewhere.
In Safe Mode System Idle Process is at 99.23%. Just perfect.

Next try.
Restart computer in Safe Mode with Networking, run PE and post new log.
