Greetings,

My pc had to shutdown and restart while coming out of sleep mode (at least that is the message I received). This is the third or fourth same message I have received in as many weeks. It then advised me to click on a link where I may be able to download a fix for this problem. The link took me to:

http://support.microsoft.com/kb/2547549#appliesto

I now have to choose a Windows program fix based on whether or not my operating system is:

a) All supported x86-based versions of Windows Vista or

b) All supported x64-based versions of Windows Vista.

Would someone please instruct me where and how I may find that information on my DELL Inspiron 9400 laptop please so that I can choose the correct one?

Thanks.
