Hello everyone. I was wondering if anyone has run into the same problem as I have. I own a HP 873n media center pc. The motherboard went out and I replaced it with another one (gigabyte). Now when i attempt to use the recovery cd's i get an error that says: "These PC recovery discs do NOT support this PC model". Could it be the DMI strings? if so how would I change it back to stock. If anyone could help me or point me in the right direction I would greatly appreciate it. Thank you, Justin.
