Alright so a year ago I bought a Lenovo PC and it came with Windows Home Premium 64-bit. Im now planning on putting together a new PC but using the same HDD. The only part I will be keeping thats from the original PC would be the HDD and possibly RAM. The windows copy is apparently OEM (According to Jellybean Keyfinder) so will I have any problems with this? If so what can I do to fix it?
