Is it possible to use a 64 bit Microsoft Windows operating system on my HP Pavilion a6220n desktop computer? The computer has the original motherboard. I have upgraded the RAM to 4GB. I have a one terabyte Seagate hard drive with a rotation speed of 7200 rpm. I would appreciate anyone's help. Please let me know if more information is needed.
Since the original OS is 32bit, there are some considerations for you to address. In order to use a 64Bit OS, it has to be a complete reinstall, an "upgrade" is not possible. If the Recovery partition is still in place that option will not restore the new 64Bit OS. The motherboard can only support 8GB with the 64Bit OS, 4GB more than now.
Unless there is a specific need to use 64Bit OS, there will not be much advantage unless the RAM is increased. Also, get all the needed drivers downloaded to a flash drive or DVD/CD BEFORE doing the reinstall.
Have a great experience in this endeavor and good luck.
