There are other issues that could be causing this as well. Such as a pop-up blocker, flash or java corrupt or in need of updating, browser needs to be reset to default settings, add-ons disabled or compatibility issues.
Although there are many benefits to running IE 64 bit it doesn't always play well with others.
Benefits of 64-bit IE: A: There are a few advantages to using the 64-bit version: •Security: DEP/NX is always on for 64bit processes. (Of course, on Vista SP1+, 32bit IE8+ has DEP/NX enabled by default too.) •Security: Memory protections like ASLR are more effective (because the address space is dramatically larger) •Security: Most bad guys only bother to write x86 shellcode, which will fail in an x64 process •It may crash less. (Because most add-ons don't load in 64bit IE, it tends to be more reliable.) •It may be faster to start up. (Because most add-ons aren't loaded. You can disable add-ons in 32bit IE if you'd like)
