My Daru2 won't boot up any more and I think it's the hard drive, but I'm not sure. The only thing that happens when I press the start button is the power on indicator light on the front panel lights up. There's no activity from the hard drive light and nothing on the screen. Should I buy a hard drive and see if I can replace it, or might there be something else wrong with it? I'm way past the warranty period, but any advice you can give me on fixing it myself would be appreciated.
