Hi Kirk, not much to go on there for me, sorry.One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications&gt;Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...PS. Safe boot may stay on the gray radian for a long time, let it go, it&#x27;s trying to repair the Hard DriveReboot, test again.If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences&gt;Accounts (Users &amp; Groups in later OSX versions)&gt;Login Items window to see if it or something relevant is listed. Or an errant process eating up RAM.Check the System Preferences&gt;Other Row, for 3rd party Pref Panes.Also look in these if they exist, some are invisible.../private/var/run/StartupItems/Library/StartupItems/System/Library/StartupItems/System/Library/LaunchDaemons/Library/LaunchDaemons

You&#x27;ve upgraded the memory modules. Reinstall the original memory and see whether there&#x27;s any improvement. Be careful not to touch the gold contacts. Clean them with a mild solvent such as rubbing alcohol. Aftermarket memory must exactly match the technical specifications for your model.The Apple Hardware Test or Apple Diagnostics, though generally unreliable, will sometimes detect a fault. A negative test can&#x27;t be depended on. Run the extended version of the test.
