My wife's relatively new (May of this year) Inspiron N5010 keeps locking up on her for anywhere from 30 seconds to 5 minutes. It gets hung up processing something. I can't figure out whats wrong though. No specific program seems to be causing the freeze, it happens when she's browsing the internet, typing in word, reading e-books or watching movies. It can happen as soon as she sits down and takes it out of sleep mode, no programs other than the windows tasks running yet or when she has firefox, word, adobe and iTunes on with 30 minutes to 8 hours of use. Mind you, when I say "freeze" I mean the computer is completely unresponsive and the HD light comes on solid until it unfreezes. I've done a complete reformat, thinking it was a factory installed software issue, but with a fresh install of windows 7 and only the up to date drivers installed it still freezes. I've called Dell to ask about this issue but they only tell me that they can fix it but for the low, low price of $200+ unless I purchase an extended warranty. Has anyone else had this type of issue or know what could be causing it and how it could be resolved? Thank you in advance for your help!
