Q: After downloading OSX 10.9.2 I can no longer access my iMac

After updating to OSX 10.9.2 (I think - cannot get into the machine to check) I can no longer

gain access to my iMac (27 inch, late 2009)

It gets as far as the grey apple start-up screen, 5 multi colour vertical strips appear - then

the screen shows a multitude of small hatched squares and does nothing else.

Can I get the Mac working again ?

iMac, Mac OS X (10.6.8)

    Try booting into the Safe Mode using your normal account.  Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.
