<p>Bluetooth devices connected to a computer system via a
wireless signal, so that the desktop of annoying cables and wires to strip.
Even if your computer does not have a built-in Bluetooth receiver, you can
create a Bluetooth dongle, the function adds the system to connect. If the
dongle is not working to resolve the situation. <br />
<p>1. Check the system requirements for the Bluetooth dongle.
If the system does not fit all the requirements, the device will not work. The
requirements for the Bluetooth dongle can be printed in the manual and
packaging. You can compare that with what is running on your computer by
clicking "Start" "Control Panel" and "System".
This gives the computer hardware. <br />
<p>2. Unplug the Bluetooth dongle, restart the computer, plug
it into a USB port. If you leave power on the computer with the dongle already
instead, the system can not detect the devices. Restart the computer and
perform this action helps to correct the problem. <br />
<p>3. Remove the dongle from the USB port and plug it into
another compound. Some USB ports do not meet certain computer hardware
detection. Changing the connection port fixes this. <br />

installation. Without the driver, the computer can not detect and use the
dongle. Insert the installation CD driver on your computer and follow the steps
on screen to install the driver on the system. <br />

The first thing I would do is boot up in safe mode see http://support.apple.com/kb/ht1455 this will boot the imac up without extensions on that includes video extensions which could be the source of the problem. See if the screen works after this, if it does it could indicate that the either video card is not operating properly or one of the drivers isn't. If you then search on google for your model of card and see if this is a known problem and you could find a work round. If it boots up as you have described it in your email it's a possiblity that the card is no longer functional and it will be expensive to repair.
If you are accurately reporting these symptoms and messages, you had more than "a bad file." You have a failing drive.
The Disk Utility repair function doesn't look at files, it looks at disk structures. If it said the drive was not repairable, then it has bigger issues. A lot depends on WHY it said the drive was not repairable, which you don't report. If it just said it couldn't repair some structure or other, you could try a more high-powered utility like DiskWarrior. But if it was because hardware errors made the drive impossible to interpret, then you have serious problems, especially if you haven't been backing your system up. At this point, the less you play with this drive before you get it to a professional, the better chance you have of being able to salvage SOME of your files (but not even that is guaranteed).
When you say your Mac "won't start up" does that include off the DVD drive? If you have a failing hard drive, your Mac should still be able to boot of the DVD.
Hello, you can test your parts using your Apple Hardware Test. But you can also see if the system profiler sees it, by going in the apple menu, about this mac, more info. The best test to do is connecting a device on it though.
Best Buy geek squad might fix Macs. Try booting up the computer with out the hd plugged in. And then plugging it into the computer after it has booted up. I've found that unplugging the power from the computer for an hour or so and plugging it back in can sometimes magically fix some booting problems.
