If you press F12 at boot when you see the Dell Logo does it show the option to run Dell Diagnostics

Remove and reseat your memory and run the test again. If it fails test with one module in at a time. If still fails contact Dell Support and Tell them the error you are receiving if you are still under warranty.

Pressed F12 key and ran diagnostics. Error 8123 memory integrity failed -  code 2000-0173.

What should I do?

Thanks for the advice Sam,

I removed one memory module and ran diagnostics - no errors.  I put the second memory module back and ran diagnostics the test failed.  This time there were two failures. The first was error 0333, the second was error 0123.  What do you think?

Should I call Dell, tell them what has happened and ask them  if  I buy  two new 4GB memory sticks can I return them if they don't pass the diagnostic test.   I will have up graded RAM from 4GB to 8GB.

You have a bad memory stick. You are getting a Memory Integrity Test Failure. You will need to replace it. If under Warranty ask Dell to replace the pair. Its good to install memory with matching pairs

Hi Sam

Notebook not under warranty with Dell, purchased 2 4GB DDR3 modules from Seifelden
