iMac beeps 3 times at startup?
I have a 2nd generation CRT iMac that just freaked out.
It runs OS 9, so naturally I reboot it daily. :0)
I went to reboot it today and it never came back to life.
It starts up, beeps LOUD 3 times, and then the green power button changes to orange and flashes FAST. No CRT, no drive activity (booting), nothing. Just a blinking orange button. Yikes.
Is she dead, Doc?

As explained by Sad Macs, Bombs, and Other Disasters (an invaluable resource; 4th Edition, page 138 for those who have it) the number of beeps indicates a problem encountered by the Mac's Power On Self-Test (POST):
? 1 beep = No RAM installed/detected
? 2 beeps = Incompatible RAM type installed
? 3 beeps = No RAM banks passed memory testing
? 4 beeps = No good boot images in the boot ROM
? 5 beeps = Bad ROM boot block or processor is not usable
If you have any extra new RAM modules, try swapping them out with the installed ones. If not, I would suggest taking your Mac to a certified Apple Service Provider to make sure it's not a deeper problem.
Good luck! ...and I know what you mean about OS 9 ? I've got the same crashing problems. (stupid AIM and Word!)

Power supply board??
Yep..I mean fluctations across the line...Power supply needs to be steady in terms of voltage & amperage..
Try plugging your imac into a different power plug...
The "cure" might be as simple as that...

It's the RAM. Apparently yours is broken?
Cannot boot off the Mac OS X install cd, no network boot, nothing except OpenFirmware. It will not go into the boot menu by pressing option. All it does is that. When I type boot, I get this message: Cannot open hd:,\\\\:tbxi and when I type mac-boot, it shows a flashing folder.
