NT Authority\System [error]

I have a problem on my Windows XP. This started like a month ago. I turned on my computer and like 5 seconds after its done loading a message pops up and says that NT Authority\System has initiated a shutdown and will restart in 1 minuted. I looked at the message or the code thingy on the bottom and said this:

C:\\WINDOWS\system32\services.exe is unexpectedly stopped with status code 128.

Am I able to fix that? If so can anyone please help me because I want to get my computer running again. ANY HELP WOULD BE APPRECIATED. PLEASE HELP ME!

Thanks. I already did all of that but I don't have msblast.exe. Also, I already downloaded all those wrom searching things and found none of them. I used the Mcafee stinger was it? Or something like that and found nothing as well.
