I have a Dell Dimension 4600 that is just over a year old an no longer under warranty when I unfortunately d/l a Windows Service Pack 2 update and now I am kicking myself :smileymad:.  The computer runs really really REALLY slow.  I have tried to uninstall the installation, reinstall Windows XP Home Edition and also Windows XP Professional.  To give you an idea of how slow the computer is running:  The last installation of Windows XP took over 6 hours to install.  That didn't include the additional time it took to install drivers and other applications.  I ran a Dell 32-bit hardware diagnostic test 3 different times and have come up with:  Error Code 0700:0120.  msg.  No Cache detected.  Cache might be disabled, defective or not present.  Then after I click okay to that error I get another:  System Error.  msg.  System_Error illegal attempt to disable.....

 

I Have popped the hood, so to speak and checked to make sure that all cards, including the memory was firmly seated inside the computer case.  Everything seems properly connected but I am not sure what cache memory the error refers to.  If anyone has any ideas or clues I would appreciate your input.
