You are making assumptions as to the cause of the problem. You need to provide more background information as to what happened before the problem first occurred. Some event usually triggers a problem of this type. Did you make any changes to the hardware or programmes installed on the computer? What are your anti-virus and anti-virus and anti-spyware arrangements?

I see I posted to one of the threads where you have read the comments that resulted in your questions. However, whilst failed memory and a failed hard drive can cause your problem there are many other reasons for this type of failure. You can get clues by observing the text on the screen and listening to the beep sounds during the boot process before it fails. Unfortunately it takes experience to know what you are looking for and the text is only there for a brief moment.

Before embarking on measures to fix the problem is important to know whether you have important data files you need to recover. If yes these need to be recovered first. Do you have access to a second computer? Is that computer a desktop or a laptop?

What exactly do you have by way of a Windows XP CD? What is your Dell model. Some Dell models have problems with capacitors! Are your keyboard and mouse wired or wireless?

Try booting with all hardware peripherals disconnected, except keyboard, mouse. and
monitor.

Have you tried Last Known Good Configuration?

A copy of the Stop Error code might help us.

Disable automatic restart on system failure. This should help by allowing time to write down the STOP code properly. Keep pressing the F8 key during Start-Up and select option - Disable automatic restart on system failure. Do not re-enable automatic restart on system failure until you have resolved the problem. Check for variants of the Stop Error message.

Background information on Stop Error message
http://msdn.microsoft.com/en-us/library/ms797159.aspx

This occurs when Windows switches into kernel mode and a user-mode
subsystem, such as Winlogon or the Client Server Runtime Subsystem (CSRSS),
is compromised. Security can no longer be guaranteed. Because Win XP can't
run without Winlogon or CSRSS, this is one of the few situations where the
failure of a user-mode service can cause the system to stop responding. This
Stop message also can occur as a result of malware infestation or when the
computer is restarted after a system administrator has modified permissions
so that the SYSTEM account no longer has adequate permissions to access
system files and folders.

when you mention "just change the RAM and re-start the windows", how
exactly do you do this and does not having a whole lot of memory left
affect doing this?

( I have a Dell desktop, it was originally Windows ME then upgrade to
XP home edition)

I am in the same position as one of the previously frustrated people
in which I get a blue screen and can't do *anything*.

I can press F8 and get to Windows Advanced Options Menu but when I
select any of the options it just goes back to the blue screen. I can
also press F2 and get the the Dell SETUP but not sure as to what or
if I can do here.

Another previous post stated "Simply remove the drive from your
system, and attach it to the other system either via internal cabling
or a USB2 drive case (about $20)." How do you do this?

Thank You,
Charyl
