Flashing question mark folder at startup


Cannot startup iMac 20 10.6.3 -all I get is a flashing question mark folder. Tried doing all the safe boots, switching the ram, starting from disc... Nothing seems to work.
And cannot reinstall operating system; all discs cannot be be seen.
Also cannot reset the ram... No chimes, either.
F@&k!!!
This is also a replacement mac and I'm on my 5th freeking iPhone, I've been a mac user my whole life... yes I grew up with the apple(still works). Now it seems these apples are rotten...seriously getting pisssed off!!!!!!

    flashing ? usually means a HDD problem of some kind

    A good HDD with NO OS will do this so will a bad HDD.

    If your ODD also does not work then you probably have a hardware issue. PSU failed??

    PSU - Power Supply

    OK it seems your system is unstable... it may be faulty RAM.

    I suggest you pull all RAM and then install 1 module only into a slot and test/boot and run at least a short while. Then do this for all modules into the SAME slot. If none boot, then try same procedure in next slot and so on till you have tested all modules in each slot.

    You may want to mark the modules with a sharpie or similar to avoid confusion.

    Make a list of what modules work in which slots. This will help determine if there is a faulty module (common fail across slots) or a faulty slot (common slot across modules).

    Alternately, you can try booting the AHT (insert DVD reboot and hold "D" till icon appears) on one of your original DVD's and run the memory test there but it cannot distinguish between bad slot and bad module so you'd still need to swap and repeat to know.

    seems odd that a HDD problem prevents boot from the DVD??

    What is the error you get?

    HDD, SATA cable, logic board are the likely causes it seems

    If it is less than a year old then get Apple to fix it, easy!

    Other option is to try to get a successful boot on the DVD and run disk util and check the HDD is SMART verified. Try repairing the disk too via utilities.

    BTW - don't exclude RAM. I had a similar issue where I could not boot from the HDD and it crashes when booting from DVD to try a disk repair. It turned out to be a dud RAM module.

    I would boot the AHT and run the extended memory test just to exclude RAM, then assuming no errors, you have to eliminate the HDD and cable as possible cause. IMO the cable is unlikely to be the cause but I never say never!

    If you are comfortable with pulling your system apart then a new HDD is a quick and easy fix and places like iFixit.com have great guides available online for free.
