My son has an emachines T4697. The power supply destroyed his motherboard. We replaced the power supply but now have to replace the motherboard. The problem is, he is a musician and has his music stored on the hard drive. He has not backed up for a long time so much of his music would be lost. We need to replace the motherboard but not reformat the hard drive. The old motherboard is an FIC VG33 that uses intel 845GE chipset. Emachines and Tiger Direct sell the replacement but it comes with a new power supply included and they want over $300. Can I replace it with another motherboard as long as it uses the same chipset? Will we be able to reload windows using the disks that came with the emachines or will we have to buy a copy of XP?
