Grey Screen

Can anyone tell me what would cause my imac a1208 take so long to boot to desktop. once switched on i get a grey Logo screen for about 4 minutes, and then turns to a Blue screen for about 3 minutes then lands on the desktop, i have re-installed snow Leopard 10.6.8 about 6 times trying to solve this issue, i have deleted partition and formatted with zero's and reinstalled os. I have ran Verify disk = OKay i have ran Verify Disk Permissions which came up with loads of problems, to which i ran the repair process. I have even run Disk Warrior. I have tried everything i know but to no avail, and is very frustrating, SPEC I HAVE IS 2GIG RAM DUEL CORE 2.0 Any help would be very much appriecated.

You might try resetting NVRAM. Also, make sure you have selected your normal startup drive in System Preferences > Startup Disk.

If this doesn't help at all, try running the Apple Hardware Test to eliminate the possibility of a hardware problem. (This can't catch 100% of the problems but it will eliminate most possibilities.)

If the procedures in the first paragraph eliminate the long grey/blue screen problem but it still takes a long time to get to the desktop, you may need to check your login items (listed in System Preferences > Accounts > Login Items tab) to see if any of them require a long time to launch.

If none of this helps, there are other things to check, like startup items & third party additions, but do the above & get back to us with your results before we get into that.

i have pressed the 4 keys mentioned in your instructions, but i am not getting a second beep, in fact the only thing that seems to work is the options key to choose what to boot with cd or hd, i have pressed option-command-p-r before the grey scree and waited nearly 9 minutes and nothin happens, is there a software reset program available.
