I have a Vista Home Premium OS SP2, 32 bit, Intel core2 @ 1.66 GHz, 2 Gb RAM, 100 Gb hard drive.
It has become very slow. I have removed all (or most) of the data but retained important programs the most important being MS Office Standard 2007.
I am looking to improve the performance. Contemplating upgrading the RAM to 2 x 2Gb = 4Gb (which I am confident I can do), also replace the drive with 256Gb SSD and upgrade/replace the OS with Win 7.
Should I consider 64 bit OS?
If so, how best to proceed?
If I stick with 32 bit, I presume I can reinstall Office 2007 with the original disc and key.
The currently installed drive fails PC-Doctor Targeted read test, SMART short self test (recommends replace drive), and Surface Scan test 2.
Any advice gratefully accepted.
