I recently built my own computer. This is third one I have built, but the first time I have really run into a problem. The motherboard is not working properly, the pci-e slot for the videocard is busted. The processor obviously is already seated in the motherboard and I have heard from people that if I replace the mottherboard I have to replace the processor to, is this true? Please give me some advice because I would really rather not have to buy a new processor as well. Thanks for you help.
