GL frame buffer object not supported by this graphics card

Hi, everyone!
I want to replace the program with a blank open animation when loading data!so I informed the setup adds a thread to load data.So I opened a thread to load the data, but there is a mistake,
“GL frame buffer object not supported by this graphics card”
how can I do
