If it is an OEM license like your subject indicates, you should go out
and buy another OEM license w/the PC, or a full retail license.

The OEM license is locked to your old PC. If you reinstall it, when
it tries to validate through the net (or by phone) it will fail as
already being registered. OTOH A retail license allows you to reuse
the license on another PC.

You can change some things on a PC to upgrade without breaking the OEM
license, but you cannot swap PCs. When you upgrade/change a PC with
either license, you usually get a "call Microsoft" message who will
conduct anything from a friendly chat (retail license) to the Spanish
inquisition of Software (OEM license) prior to giving you a rego code.
