I turned my computer on yesterday and got this message in a blue screen. I called tech support and the guy had me do a few things I didn't understand, and then run a diagnostic which showed that all of the components "passed". My question is: I've only had this computer for about a week, and since HP has a 21 day return policy, I can return it. So, should I return the computer while I have the chance? Is this hardware failure screen a big deal that will bite me later? Thanks.
