|"Specs: Windows 64"|
Why didn't you list the complete system specs? Windows 64 doesn't tell us much. Is it Windows XP, Vista or 7? And what does having a "slow PC" have to do with downloading a copy of Win7 from the internet? The system may be infected or it may not have enough memory to run the Windows version you have installed. And if it's an OEM system (Dell, Gateway, HP, etc), you may still be able to do a factory restore or create the recovery discs to be able to reinstall Windows from scratch. We can't tell you how or where to download a copy of Windows 7 because it violates forums rules - Google will show you the way.
