Motherboard: MSI International MS-1352 Ver 1.000


CPU Usage spikes as soon as you log into the computer. It’s usually one of two processes:
Lsass.exe 80% - 100%
Or svchost.exe 97-100%
Usually, any time a browser is opened or networks are looked at, one of the above processes takes over the computer.
Essentially the CPU is constantly overloaded and it makes all tasks on the computer aggravatingly slow. It’s really frustrating for anyone to use this computer.

After waiting for about 15 minutes with no open applications, the CPU usage went down to 5-10%. When Google chrome was opened: CPU usage temporarily is 100% on chrome.exe, then 95-100% usage on lsass.exe. This is happening with no active network or internet connection.

The MSI X340 13" laptop supports a maximum of 2 GB of RAM, so there's no option to add more to it.

Between the combination of its processor and its RAM, it's not going to be speedy and snappy running Windows Vista.

It appears to have multiple users, so it's my guess there's a large number of running processes and it's infested with malware, spyware, etc..

Do the following in the order that they're listed.

--------------------------------------------------------------

Go here, then click the large blue "Download Now @ Bleeping Computer" button to download and save AdwCleaner.exe to your desktop.

Close all open windows first, then double-click AdwCleaner.exe to load its main window.

Click the "Scan" button, then allow the scanning process to finish.

Click the "Logfile" button.

When the log appears, save it.

Return here to your thread, then copy-and-paste the ENTIRE log here.

When you close AdwCleaner, ignore the warning that appears, then click "Yes".

--------------------------------------------------------------

Go here, then click the large blue "Download Now @ Author's site" button to download and save TFC.exe (Temp File Cleaner by OldTimer) to your desktop.

After it's downloaded and saved, close all open windows.

Double-click it to load its main window.

Click the "Start" button.

If there are a large number of temp files and/or there are multiple user accounts, the temp file deletion process may appear to freeze or may take a few minutes, so be patient.

After the temp file deletion process is finished, restart the computer.
