I am also experiencing unexpected shutdowns. I have an HP Entertainment
laptop that I purchased in Feb of this year. It will randomly shutdown. It
seems at first it happend mostly when I was streaming music/videos or when I
was ripping a CD, but has occured other times as well. My favorite is when
it happens while my maching is in sleep mode. I took it in and the techs
couldn't find any thing wrong. When it starts to shut down I will hear this
obnoxious clicking noise and then a blue screen will appear that says that an
unexpected error had occured. From there my machine will restart and then I
will get the "Windows wasn't shutdown properly" screen. After that all is
well for a few more days. Any suggestions? I am very unhappy about the
situation considering how much I paid for this product.
