Episode 1050 (2:25:25)

Steve from Big Bear, CA

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.
