Hi,  The flashes are because they were activated in the Systems Preferences > Universal Access > Hearing to turn on when the computer beeps. This is to alert those Mac users who cannot hear, so that they are aware of the alert. They will be able to see the alert. It has nothing to do with the motherboard or problems with it.  :-)
As for turning it on at all - try holding down the shift key while booting the Mac. This gives it a safe boot. If it boots that way, you know it can boot. Then go to Disc Utilities and select 'repair permissions'. That might take awhile, but should help.  You might have to reinstall the OS to make all work again. That's IF the tea didn't do its thing. It's a good idea to get a skin for the keys. They can be found at most stores that carry Mac products, or online at the Apple store. Good luck.

    Hi Eric,
      You shouldn't have to deal with the mouse at all to turn on the Mac. It should just turn on. If you can hear a chime when you turn it on, it's a very good sign. It means you have a happy Mac.  :-) No chime is an "uh oh". Think repair shop.

    If you can buy Tech Tool or Disc Warrior you will have excellent tools to find out what is going on. They are both excellent diagnostic/repair tools for the Mac and you will be using them, hopefully once a month or so just to keep things up and running smoothly. 

    Have you worked with Disc Utilities yet? You will find it in your Applications folder. I keep my labeled in red so that I can find it easily. Disc Utilities is always the first place to look at repairing problems. You want to run the "Repair Permissions" action. It takes awhile, but just go get yourself a cup of coffee. It will repair what it can, and that's a good thing!  Shari

This is a question from a friend of mine who recently was given a used imac. Any ideas what he can try doing? when I plug it in and turn it on I get a grey screen with a little icon in the middle (looks...

What your friend is seeing, is an indicator that the Mac 333 Mhz, is not able to boot up to recognizable Mac OS volume. This means that Mac OS volume is either damaged or has some how been corrupted.

Apple advises the only fixes for such an issue with this class of their "legacy computer" series is to back up the data on the hard drive if possible and reinstall the Mac OS version is was operating with, or simply go a step further and upgrade to the highest version of the Mac OS X family of operating systems, that this iMac G3 qualifies for.

Here is a link from Apple support for resolving this issue for this legacy mode;
Macintosh starts up to Grey Screen

If your friend is interested in knowing what is the highest version of Mac OS X he can install on his iMac 333,, it would be Mac OS X 10.3 Panther.

This version is the highest upgrade for the iMac 333 because Mac OS X 10.4 Tiger will only work with Macs that have a built-in Firewire port.

Here is the technical specifications link from Apple for this model:
Technical Specifications - iMac 333 Ghz (1999)

This should help.

I have brought a Belkin printer adapter Model Number F5U002 and it only has software in the box for Windows but I have a imac where can get software for my imac Thank you Greg

Belkin seems not to be very proud of this product, it's no longer on their support website...
There seemed to be a special MAC version of this product, and I'm afraid you are among many people trying to make use of this adapter and not being able to obtain drivers for Mac or for Windows Vista for that matter...
If you bought this recently, you'll have to return it I think and look for some other, more Mac-friendly USB to Parallel adapter that has it's manufacturer's support.
