Can't find the option in BIOS to enable 64 bit architecture on Intel DP55WB mother board. The processor installed is core i5 720 that supports the 64 bit architecture. Please help me in this one.
Yes You are right, The CPU is i5-750 2.67 GHz with 8MB cache. The link to the CPU is http://ark.intel.com/Product.aspx?id=42915
The HPET mode is present in the BIOS and is set to "ENABLED" No further subcategory to select 32 or 64-bit.
I have tried to install a fresh copy of Win7 SP-1 64-bit but again it gives me error of no supporting hardware present.
