I found that my PC can run a 64 bit OS, but my RAM is only 1.5 GB. Am I doing something wrong by installing windows 8.1 32 bit? Is my system capable of performing better? What happens if I install the 32 bit version of the OS on a 64 bit processor?

and these are my specifications:

With only 1.5G of RAM 64 bit will be a waste honestly the MAIN and most common advantage of 64 bit (x86_64) is the fully optimized use of RAM over 4Gb (without PAE).. 64 bit systems can either 32 and 64 bit OSes however the reverse is a major no-go. In short, given the lower specs the 32 Bit OS is better for your use-case..

With your current amount of RAM its better to continue with 32 bit. when you upgrade your ram over 2 Gb upgrade your os to 64 bit as there is a ram limit for 32 bit. Hope its clear.

Generally, almost everything will work ok, but some programs will not.
