This first came up when a faulty left fan caused my computer to heat up into a stall, which forced me to turn off the computer without shutting down (for the first time since getting the computer, albeit second hand). From then on it's been consistently going to the blue screen. The obvious solution would be to run disk utility from the install disc, but I can't load any discs from the drive (I've had this problem already). Holding down C does nothing, no disc will load from startup. Any ideas? Any way to do this without the install disc? Or any other way to run disk utility?
