Beginning dump of physical memory

A few weeks ago I was playing Age of Empires III on my laptop(inspiron 6000) when the screen went blue and brought me back to the desktop. Confused and upset, I started the game back up again. A short while later, 10 minutes or so, a blue screen came up with this message:


A problem has been detected and windows has been shut down to prevent damage to your computer.

KERNEL_DATA_INPAGE_ERROR

If this is the first time you’ve seen this stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any windows updates you might need.

If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use safe mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

I then shut my computer down and immediatly restarted it. While it began booting, or so I thought, this message came up:


Internal HDD HARD error!
Strike the F1 key to continue, F2 to run the setup utility




I thought I fried the hard drive! The next day I started it up, waiting for that screen again, but to my surprise it started up as though nothing had ever happened.

Now I was working with photoshop last night and the blue screen came up, and again today while I was installing updates (hoping these would fix the problem).



Does anybody know what has happened to my laptop? My warranty(of course) is expired and I have taken good care of it since I purchased it (17 months ago).

Any help would be greatly appreciated.
