Sorry to hear about your problems,
1st. We need to know what kind of computer, Laptop or PC.?
2nd. What kind of error messages are you receiving, when the unit try's to startup. ?
3rd. Have you tried to back step and replace the new (not working memory) with the original
Note….. Always have power disconnected from the unit.
Disconnect all devices, lay unit on its side, where you can see comfortably.
Always, double check your work. Take your time.
Chances are, you do not have the memory seated properly.
Look at the memory and try to fit into the bit slot. Do not force the memory.
If you are receiving a Beep message when starting unit, it is not seeing the installed memory.
Install one piece at a time and try powering up unit.
Don’t mix memory, work on one unit at a time.
Hope this information has helped you.
Readers, please rate you technician’s.
Thanks
John Ray
