Start-up light blinks twice, and computer doesn't turn on.

History

Computer worked fine until one day upon turning it on the start-up light blinks twice, with a pause then blinks twice again. It repeats this loop with nothing coming to the display. If this is simply a hard drive issue that would be great as I am worried it is a bigger problem. Any information would be much appreciated. Thank you in advanced.

The 2 beeps = Incompatible RAM type installed (for example, EDO) according to Apple.

I would re-seat the RAM and remove any added RAM. Also check that they are in the correct slots and a matched pair. Bad RAM gives three blinks.

I found it works 90% if you use DDR 3200 Ram.

BTW thanks Mayer!
