Q: My mac mini wont turn on but there is power to it as the usb port charges my iPad

My mac mini wont turn on but there is power to it as the usb port charges my iPad. My monitor uses a HDMI cable when the mac mini is off it says no input received which it does not say so it is receiving some signal from the mac mini. I have tried a different cable and a different monitor/ hdmi cable. The fan isnt running there is no start up noise but the little light on the front blinks every 4-5 seconds. Im booked in to see a GENIUS on sunday but I was wondering if there is anything I can do in the mean time. The mac mini is only 8 months old if that. Any ideas people? Oh the mac is also running mountain lion and has been since the day of release i've never had a problem up until this.

Mac mini, Mac OS X (10.7.2)

    The following table lists the new tones and their meaning:

     

    Tone(s)          Description

    1 tone, a 5-second pause, repeat          No RAM installed

    3 successive tones, a 5-second pause, 3 successive tones          RAM does not pass data integrity check

    1 long tone when holding down the power button          Firmware upgrade in process. See About firmware updates for Intel-based Macs for more details.

    3 long tones, 3 short tones, 3 long tones          Firmware restoration from CD in process. See About the Firmware Restoration CD (Intel-based Macs) for more details.

    Can you count the beeps or flashes?

     

    1 beep = no RAM installed

    2 beeps = incompatible RAM types

    3 beeps = no good banks

    4 beeps = no good boot images in the boot ROM (and/or bad sys config block)

    5 beeps = processor is not usable

     

    In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.

     

    Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.
