Hi, 1. Did you make any software changes to the computer recently? Check if the issue exists in Safe Mode, if the computer works as expected in safe mode then we can troubleshoot the issue in clean boot state.Step A. Refer to the article below for safe mode steps in Windows XPA description of the Safe Mode Boot options in Windows XPhttp://support.microsoft.com/kb/315222 Step B. You are required to perform a clean boot to find the program that is causing this and then disable or remove it.How to configure Windows XP to start in a "clean boot" statehttp://support.microsoft.com/kb/310353/en-usNote: After you have finished troubleshooting, follow the steps as explained in the article to reset the computer to start as usual. Also I would ask you to install the Windows Xp Service Pack 3 for a stable performance.It improves the reliability of Windows by installing the latest software updates - new drivers for the hardware and more.http://www.microsoft.com/downloads/en/details.aspx?FamilyId=68C48DAD-BC34-40BE-8D85-6BB4F56F5110&displaylang=enHope this helps.Thanks and Regards:Shekhar S - Microsoft Support.

How much RAM does your computer have?Try Ctrl+Alt+Delete to select Task Manager and click the Performance Tab. Under Commit Charge what is the Total, the Limit and the Peak?You should be able to gather more information from Task Manager. With the Processes tab open select View, Select, Columns and check the boxes before Peak Memory Usage and Virtual Memory size. What are the figures for the 6 processes using the largest amounts?I would check for error reports in Event Viewer.Have a look in the System and Application logs in Event Viewer for Errors and Warnings and post copies here. Don't post any from than more than 48 hours ago. You can access Event Viewer by selecting Start, Control Panel, Administrative Tools, and Event Viewer. When researching the meaning of the error, information regarding Event ID, Source and Description are important. A tip for posting copies of Error Reports! Run Event Viewer and double click on the error you want to copy. You will see a button resembling two pages. Click the button and close Event Viewer. This places a copy of the report into your Clipboard. Paste into the body your message. Make sure that this is the first paste after exiting from Event Viewer.Select Start, All Programs, Accessories, System Tools, Disk CleanUp to empty your Recycle Bin, remove Temporary Internet Files and other selected options. I also recommend you click on the More Options tab, System Restore and remove all but the latest System Restore point. Run Disk Defragmenter.Using the System restore option is most appropriate when your system is running slow and you need to increase free disk space on your C partition. If you have errors which might be resolved using System Restore to put your system settings back to before the error first occurred do not use this option.If more than one person uses the computer and they have their own user Log on you need to run Disk CleanUp in each user profile to remove all unwanted files.A better programme than Disk CleanUp is cCleaner but note that cCleaner will not handle System Restore points. Removing older restore points can be important if you have limited free disk space. cCleaner comes with a Registry tool. Do not use this tool as like any registry cleaner it can lead to the creation of very difficult to resolve system errors.http://www.ccleaner.com/download Hope this helps, Gerry Cornell
