I have an eMachines T6003 with an AMD Athlon 64 Processor and am running the full 4gb of ram. My current operating system is Windows XP 32 bit. So I was wondering if it would be possible for me to do a clean install of Windows 7 64 bit onto my computer? Because whenever I load the install disc it says that it is not a valid Win32 application? Any help onto this would be great.
