Hello everybody
sorry if I have posted in the wrong section but im desprate for help here.
Today I went to start up my mac and got to the bit where the grey apple aprears and the spinning gear like thing. also I notied a bar under neath all that not even fill up 1/4 of the way before dissapering. I did searches on the problem and tryed all of the troubleshooting boot up keys but still nothing.
I then put my install dvd in and then nothing happens I try everything the C button on start up the option key and only my mac hdd and windows hdd partition show up.

So now im stuck with a mac that wont load past the grey apple or boot up my install dvd to fix the problem.
Please help

and also im running boot camp with windows 7 on my imac. that partition works fine but.

Thanks in advance
also I dunno if this is a problem but I have snow leopard installed on my imac but my boot dvd is 10.5.6 I dont have the snow leopard dvd

Any specs of what machine you have would be useful... but here we go...
Try resetting SMC, MVRAM and PRAM
Guides below:

Resetting your Mac's PRAM and NVRAM
Intel-based Macs: Resetting the System Management Controller (SMC)

Thats all good then, I was bargaining that you had an intel machine and gave you the intel guide for resetting the SMC, hopefully it will work for you.
Post the results

Basically make sure the computer is off. Unplug the power supply and remove the battery if it is a laptop. Hold down the power button with everything removed for 10 seconds, then replace everything into it and power it back on.

nope no luck with any of them man when I did the SMC my imac went really loud like it went into over drive or something that did nothing. wouldnt even load up my windows partition. So I unplugged it for a minute or two that worked but still no mac side working
then tryed the MVRAM and PRAM reset like I already have but again no luck.

What im seeing is Grey apple appears. then a loading bar at the bottom of the screen fills not even a 1/4 of the way up with grey. Then disappears and that little gear like spinning thing appears and then the machine will not go any further.

Thanks for your help but man
