My PM 8600 doesn't want to boot. I can power it on via the little case button or the keyboard power button but whenever I do, the screen doesn't display at all, it doesn't even make the start up chime. It won't even give a chime of death. The hard drive will spin for a few seconds, but that's about it. There is no response from the keyboard (not even a 'three key salute' will work), no screen, no machine activity whatsoever. It just stays on with the fans running. Any ideas or possible solutions? |

Do those have a removable ROM chip? If so, check that. Also, possibly power supply.

Prior to the "bong" the Mac performs a sub-system test. It does not check whether a sub system is working just simply if it is present. These checks would included the memory controller, PCI bus controller, video, scsi etc. If the system gets power but there is no bong, then as sub-system has failed. In a different post you mentioned changing processor cards. If you did so you might recheck the seating of the card. As a general rule if you have added and cards or memory to the system, it is a good idea to hit the reset button on the mother board. A Mach V 8600 (250 and 300MHz models) are awesome machines. I used one for several years and was always delighted with their performance. Since these machines have the cache on the processor card instead of the mother board, they will perform slower with Gx upgrades than the non-Mach V 8600s. bill

I had the same problem with one of my 8600's; turned out to a badly seated processor card. It may seem to be properly seated but something doesn't line up. Try removing and re-seating that card.

Quote from: "mac2geezer" I had the same problem with one of my 8600's; turned out to a badly seated processor card. It may seem to be properly seated but something doesn't line up. Try removing and re-seating that card. Thanks for the replies everyone. I reseated the CPU card and all works well now. Thank you! Naturally I would have thought that upon failing such a pre-boot self check a 'chime of death' would have sounded.

Glad it works. If the chime of death sounds, you WILL know it. Screen goes black. The mac icon is dead. And it screams a horrible death sound.
