Ollie has a Sony computer with a motherboard that went bad. His brother has a similar model and he's wondering if he can put it in his computer or take the hard drive out. Leo says that Windows will see it as a different computer and he'll have to reactivate Windows. He'll also need to install new drivers.
Devon thought his video card was failing so he removed it and now he's getting no post codes. Could the motherboard be bad? Leo says it could be a number of things, including loose cables or CPUs, memory etc. He should try reseating everything. Leo says Devon may have also lost the CMOS battery in the process, but that wouldn't fail the post.
Steve is having trouble with his screen refreshing a lot on his PC after having changed motherboards. Leo says that swapping out a motherboard is a huge change and it means he needs to do a clean reinstall of Windows after formatting the hard drive. Since Steve is using an OEM copy of Windows, it's trying to install the wrong video drivers. Steve should delete all the drivers from the device manager and reboot.
Leo says most of his trouble will be with Windows Genuine Advantage, which will think he's installing it on a new computer. He'll have to call Microsoft and let them know he's changed the motherboard. He should also make sure he gets all the drivers he needs before he installs the new motherboard. Then he will install them immediately after booting into safe mode in Windows.
