Hello and thank you to all who read this. Recently while I was eating dinner and left my laptop open I got the BSOD and the laptop shut down. All I was able to catch was "Bad pool header"

I was doing nothing with the laptop it was simply sitting on the desktop. I am not that familiar with this laptop because I rent it from a store. However I was able to find these specs:

Samsung Windows 7 Home Premium
AMD A4-3300m APU with Radeon HD Graphics 1.90 GHz
RAM: 4.00 GB (3.48 usable)
64 bit OS

I am wondering what this blue screen could mean..or should I not be worried? If worse case scenario I would have to have the store send the laptop to another state to be repaired which would take weeks...Also could someone explain to me why I am seeing A local disc (C:) And a local disc (D:) because the C drive is saying 82.7 GB free of 178 while the D drive is saying 250 GB free of 267 GB...when I click D drive it lists Samsung Recovery folder and a system software folder.

Any advice is greatly appreciated! I currently use Vipre Anti-virus and also Cloud System Booster. I am up to date on all windows updates, and I defrag and run disc cleaner..but that is about all I know to do
