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.

20 meg and I feel like my computer could need a little boost to speed up as well. It is a Compaq 3300+AMD Athlon 64 processor with 512 MB PC3200 DOR SDRram memory, 250 gb/7200 rpm. I have done defrag, utilities cleaners,start-up cleaning.
