Do try to attempt to clean install first before resorting too buying new hardware. May need to change your boot order to DVD drive - first boot device.
As far as, replacing the hard drive. Yes - you can reinstall OEM on a replacement hard drive in the same computer.
When it's an OEM license
1. You can reinstall as many times as needed on the same computer.
2. You can replace the hard drive and reinstall Windows OEM on the same computer.
3. You can not move OEM to a different computer.
Difference Between a Full/Upgrade/Retail License and an OEM/System Builder License.
OEM licenses of Windows:
1) Are bound to the first computer installed on and can't be moved to a different computer.
2) Can not do an in place upgrade from older versions of Windows, only a clean/fresh install is possible.
3) Offer no free support from Microsoft.
Hope this helps'
