Open the Task Manager (Ctrl+Alt+Delete).
Under the Mem Usage tab, which program is using most of the memory?

I too also had the same issue
the process is svchost.exe its related to Windows Updates
try to look at it for it may be the cause of the problem
check for that and tell us if the CPU Usage of it is high
and how much memory it uses

The Svchost.exe process may spike the CPU usage to 100 percent during update detection or update installation. Also, the Svchost.exe process causes the computer to stop responding for various lengths of time...The Svchost.exe process produces an access violation during update detection or update installation...

Hotfix for issues that involve the Svchost.exe process

You can download and use Process Explorer to investigate all processes and gather additional information to identify and resolve problems. This tool will show the process CPU useage, a description, company name and its path (location). If you right-click on the file in question and select properties, you can gather additional information.

The Process Explorer window shows two panes by default: the upper pane is always a process list and the bottom 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.

Also see How to determine what services are running under a SVCHOST.EXE process and What is svchost.exe?.

I agree with the problem, but the HotFix has never worked for me yet. So, If Quietman's fix doesn't work, try this:

1. Click Start->Run, type "services.msc" (without quotation marks) in the
open box and click OK.
2. Double click the service "Automatic Updates".
3. Click on the Log On tab, please ensure the option "Local System account"
is selected and the option "Allow service to interact with desktop" is
unchecked.

4. Check if this service has been enabled on the listed Hardware Profile. If
not, please click the Enable button to enable it.
5. Click on the tab "General "; make sure the "Startup Type" is "Automatic".
Then please click the button "Start" under "Service Status" to start the
service.
6. Repeat the above steps with the other service: Background Intelligent
Transfer Service (BITS)

Step 4: Re-register Windows Update components and Clear the corrupted
Windows Update temp folder

1. Click on Start and then click Run,
2. In the open field type "REGSVR32 WUAPI.DLL" (without quotation marks) and
press Enter.
3. When you receive the "DllRegisterServer in WUAPI.DLL succeeded" message,
click OK.
4. Please repeat these steps for each of the following commands:

REGSVR32 WUAUENG.DLL
REGSVR32 WUAUENG1.DLL
REGSVR32 ATL.DLL
REGSVR32 WUCLTUI.DLL
REGSVR32 WUPS.DLL
REGSVR32 WUPS2.DLL
REGSVR32 WUWEB.DLL

After the above steps are finished. Sicne temporary folder of Windows Update
may be corrupted. We can refer to the following steps to rename this folder
that

1. Click Start, Run, type: cmd and press Enter. Please run the following
command in the opened window.

net stop WuAuServ
(note, you might need to reboot before the net stop command will work)

2. Click Start, Run, type: %windir% and press Enter.
3. In the opened folder, rename the folder SoftwareDistribution to SDold.
4. Click Start, Run, type: cmd and press Enter. Please run the following
command in the opened window.

net start WuAuServ


I have had 100% sucess with this procedure when the issue was what was mentioned above.

good luck,

rigel

Hi,
thanks for all the great advice, but she has decided to do a fresh install of windows, as she has all sorts of stuff running around, including the likes of trojans again, her pc takes 20 minutes to boot up now, and you cant do anything else after that, what i would like to know is, she has put her first disk in (hp restore plus) in safemode this has finished and is now asking for the windows xp home disk, but it keeps spitting out that cd, i personally brought this cd with key and have used it to formatt the computer as it belonged to me and she brought the pc off me.i then got her to restart and hit f8 and select boot form cd, but then spat the cd out. not sure wat to do

Did you mean eject the cd out?
If so (not sure what may be the cause)
could be hardware problem
