my Inspiron 15Z 5523 beeps 4 times and doesn't start.
I have tried reseating the memory modules and i have tried pushing the Reset button. Neither one worked.
What could I do to fix the problem?
Build yourself a new Windows install medium (USB key or disc) using the Intel IRST driver (first one in the link below if you're using 64-bit 7; second for 32-bit).
For instructions on slipstreaming a driver into a Windows installer, see
