Had 64 bit but had to reset hard drive and now i have a 32 bit windows 7

Ok here's the problem i use my computer for gaming and i had to reset the hard drive to fix a problem. Butwhen i re installed windows i only have a 32-bit disk even though my computer was once 64-bit. So my computer right now is windows 7-32 bit but is there a way i can get it to be 64 bit without having to buy a new disk because 32-bit really limits my pc to that it is capable of doing.

What did you reinstall Windows from, the factory recovery partition on the hard drive, factory recovery discs, or some other method?

well i had to delete my whole hard drive pretty much and then install windows again but i only had a 32-bit windows disk. So i had to delete my OS completely and download it again if that makes sense.

If it's a custom-built PC (I assume it is since you posted the motherboard model) how did you install the 64-bit version which it originally had?
