2.5 quad G5 will not boot. It will either boot to the gray screen, with the apple logo and the turning timer, or sometimes it will just go straight to a blue screen. This computer started fine, except it had infrequent kernel panics, 6 months ago when put in storage. Now when pulled out and attempted to use again this is happening. I was told that a bad processor may be the cause of the kernel panics. However, the machine never refused to boot when in operation before storage. Also it looks as if LED #2 and #7 are lit up. I'm kind of at a loss. It will not boot from the install disk or in in safe-mode. The PRAM has been reset, as has the PMU. No visible signs of coolant leaks. Any tips, or ideas would be greatly appreciated at this point.
