I'm using DELL Inspiron N7110 laptop win Win 7 64-bit Home premium
When I was doing an automatic windows update, OS crashed & did not allow me to boot & give BSOD error.
(during automatic update I was using card-reader to read a card)
System restore did not work. Diagnostic test went fine. No issues with any hardware

I tried re-installing the OS from scratch. Once the installation completes & restarts, it again gives BSOD error.
I replaced the harddisk with another one but still getting the same issue.
Tried changing the RAM in the RAM slot, tried with 1 RAM at a time. This also didnot work out.
Even now the diagnostics are clean.

Can anyone suggest how to fix this issue ?
