Error Spooler Subsystem App

You see exactly what error I had last March 10, 2010. It is about Spooler Subsystem App which encountered a problem. I printed screen it for my personal use. Honestly, I was scared as I saw this appeared on my desktop. I thought my computer collapsed already. I am thinking of buying anew one now. I will see when finances are possible.

I found out in Microsoft Support that when "you try to start or stop the Print Spooler service, or when you click Start and then click Printers and Faxes, you may receive the following error message: Spooler subsystem app has encountered a problem and needs to close."

What to do when you encounter this problem? You can try to visit the Microsoft support in this link, http://support.microsoft.com/kb/810894/it.

I guess my computer is working good again even though, I really did not make any thing after I encountered this problem.
