Hi Felix_1989,
Two beep error code on Dell Inspiron N5010 indicates No Memory (RAM) detected. I’d suggest you to reseat the memory on the system and try switching ON the system.
We will have to isolate the issue is with the RAM slot or RAM modules installed in the computer. I’d advise you to Interchange the memory or reseat the memory module(s) one at time in each slot and check for the issue.
You can contact our Dell Support at phone numbers in the link below.
Please let me know if this helps.
