Boot pc into safe mode..... still freezing?
Are you loading from a cd??? It could have a scratch, bad image. Also, onboard recovery are known to be faulty(basically if windows goes bad w/out virus, spyware problem; usually means corrupt image, and same could be true from onboard recovert. Make sure no devices expet keyboard, mouse and monitor are hooked up whenever you preform a reinstalation. I know for a fact that if a printer is hooked up it will mess up everything. Remove any add on cards besides video ( wireless network card etc..) Try another reinstall, used advanced options and preform full recovery.
Still freezing??
Check memory, unseat, switch slots reseat.
If still having trouble , can you remove hard drive and install it into another system temporarily ? Try installing to that hard drive in the alternate pc. Or install an already images hard drive in this system and see if it boots up.
Why are you reinstalling OS? Did it crash/freeze? Perhaps there is harware damage, bad ram, loose cable, warped processor. Did the system overheat?.... Is it overheating?....
Don't be daunted yet, stay calm, above all be PATIENT!!! Sometimes these things become a pain, but realise... their could be several things affecting this reinstall. Just keep at it. We are always here to help.
