I see its working.  One comment on your 64 bit OS and only 4GB of RAM.  A 64 bit OS uses more of the basic memory than a 32 bit OS does, thus there is less left for programs.   I would seriously consider upgrading memory if the motherboard you have will accept more than 4GB. 

By the looks of it the system might be 7 or 8 years old. I suggest upgrading to a new PC when Windows 10 arrives. Or Windows 11 if you need to wait that long (if it doesn't conk out by then).
