System ShutDown? Memory Dump?

[Dead Phoenix]

I don't know how many of you have this or had so I'll ask anyway.

I haven't used my computer in a while and I decide to use it last night. I was updating the system and I was online then my computer got the Blue Screen. When I started it back up I lost about 3 gigs of memory. Now this has happened 3 times and I lost about 7 gigs all together. I keep geting this stupid report saying this:

If in the event that your hard drive is failing mechanically you should backup your data quickly onto a external hard drive.
