Idk, when I upgraded winwos 10 installled the 32 bit OS, but as i remembered, this PC had Windows 7 64 bit OS. Is there any way to change it? or I need to buy a new PC and give this one to the gods as an offering?
I can see your processor is a x64, so it is compatible with windows 10 64 bit operating system , just find Windows 10 installation disc and switch to 64 bit OS
You can use Google to find instructions of how you can switch to windows 10 x64 bit
