have had a recent problem while trying to play Battlefield 2 & Battlefield 2142. I will be playing for a few minutes, when suddenly the game will start to jerk and run very poorly. When this happens, if I ALT + TAB, and check the task manager, a system file titled "SYSTEM " will be running, usually using about 25% of system resources, although I have seen it as high as 37%. I have not noticed this happen with any other games, but the Battlefield games are my most processor hungry. I have had the same setup for a while and both games worked fine till recently. The only recent changes I can think of are an upgrade to internet explorer 7, and installing a new cordless mouse & keyboard. I have tried uninstalling the mouse/keyboard driver, re-installing the games, doing a system restore (but I keep getting told that the system cannot be restored), and finally, running a windows repair, but nothing has worked.

Google searches on "system" are a waste of time, so, I was hoping that maybe someone more knowledeable than me can give me some guideance, or may have come accross this before.

If it makes much of a difference, I am running a P4 Northcot 3.2GHz, 2 Meg RAM, x1950PRO graphics card (512 mem) and Windows XP Pro as my operating system.

In order for anyone to properly assist with your problem, you need to be more specific.

What type of anti-virus are you using? Have you performed any anti-spyware scans? Have you tried doing your scans in "SAFE MODE"? Are you doing scans while logged into the Administrator's account or an account with administrator privileges?

Do you know the file associated with this process and its location? Know that will help give us a clue as to whether or not your dealing with malware.

Anytime you come across a suspicious file, search the name using Google, BC's File Database, File Research Center or the Process ID Database.

Also see How to determine what services are running under a SVCHOST.EXE process.

Determining whether a file is malware or a legitimate process sometimes depends on the location (path) it is running from. One of the ways that malware tries to hide is to give itself the same name as a critical system file. However, it then places itself in a different location on your computer. A file's properties may give a clue to identifying it. Right-click on the file, Properties and examine the General and Version tabs.

You can download and use Process Explorer or Glarysoft Process Manager to investigate all running processes and gather additional information to identify and resolve problems. These tools will show the process CPU usage, a description and its path location. If you right-click on the file in question and select properties, you will see more details about the file.

The Process Explorer window shows two panes by default: the upper pane is always a process list and the bottom pane either shows the list of DLLs loaded into the process selected in the upper pane, or the list of operating system resource handles (files, Registry keys, synchronization objects) the process has open. In the menu at the top select View > Lower Pane View to change between DLLs and Handles.

If you have XP Pro, you can use Tasklist to display a list of active processes.
Go to Start > Run and type: cmd
press Ok
At the command prompt type: tasklist /svc >c:\taskList.txt
press Enter

Go to Start > Run and type: C:\taskList.txt
press Ok to view the list of processes

The /SVC switch shows the list of active services in each process. For help and syntax information, type the following command, and then press ENTER:
tasklist /?
or see: Syntax options

You can also use the WMI command-line utility to view and list processes.
Go to Start > Run and type: cmd
press Ok
At the command prompt type: WMIC /OUTPUT:C:\ProcessList.txt PROCESS get Caption,Commandline,Processid
or: WMIC /OUTPUT:C:\ProcessList.txt path win32_process get Caption,Processid,Commandline
press Enter

Go to Start > Run and type: C:\ProcessList.txt
press Ok to view the details of all the processes.

If you come across a suspicious file which you cannot find any information, the file has a legitimate name but is not located where it is supposed to be, or you want a second opinion, submit it to jotti's virusscan or virustotal.com. In the "File to upload & scan" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.
