This is pretty sure that there is no problem with the Hard Disk. I guess it is a fault with the motherboard ASUS P5N73-AM. Please suggest all possible options \ solution to overcome this issue.
I already told you what's wrong, it's not my fault you won't believe me. IRQL_NOT_LESS_OR_EQUAL is a crash caused by a device driver problem. You can tell me whatever you want, but if that's the message you're getting,
it is a driver problem.
Specifically, IRQL_NOT_LESS_OR_EQUAL happens when memory is paged and the a driver attempts access to that block of memory. This results in a disk access, but disk accesses aren't legal at this interrupt level (thus the name of the error). So, the driver requires an operation that can never complete, and your computer crashes.
The same hard disk has been tried on a different mother board, RAM & SMPS and I was able to install the OS. This is pretty sure that there is no problem with the Hard Disk.
I know, I told you in my first post that it was a driver problem.
