There's no detail about the PC but video roll was usually a failed monitor or graphics card back in the day. Here we have no PC/Monitor/System detail so can't start except to point to GPU and/or monitor. Could be drivers so the easy test for that is to get to the BIOS SCREEN.
Turned on computer and it is uncontrollably rolling. Can’t read anything and can’t see mouse pointer. Tried turning on/off, tried all mouse button/ checked all lead connections
