I'm having problems with my lappy today. I've had two blue screens of death so far, and ran a diagnostic which said it couldn't locate the hard drive. I'm back on and trying to get it sorted. Going to back anything up that I might not already have done and contact the nice people at Dell. I've had this before where the hard drive wobbled and then it died so if I vanish, I'll be back! Lol. Talk about bad timing...and thank god for warranties!
