重装系统后，我的qt项目预览为空，网上搜索资料都说是因为显卡问题，无法访问opengl2.0，我就纳闷了，如果是这样的问题，在重装系统之前也应该无法访问哪，今天安装了qt5.3显示的异常与qt5.4显示的异常又不一样了。希望各位大侠能给些指点。如有答复，不胜感激哪。
qt5.3环境下异常信息如下：
getProcAddress: Unable to resolve 'glGenBuffers'
getProcAddress: Unable to resolve 'glGenBuffersOES'
getProcAddress: Unable to resolve 'glGenBuffersARB'
getProcAddress: Unable to resolve 'glGenBuffersEXT'
QOpenGLBuffer::bind(): buffer not created
QOpenGLBuffer::allocate(): buffer not created
QOpenGLBuffer::release(): buffer not created
getProcAddress: Unable to resolve 'glBindFramebuffer'
getProcAddress: Unable to resolve 'glBindFramebufferOES'
getProcAddress: Unable to resolve 'glBindFramebufferARB'
getProcAddress: Unable to resolve 'glBindFramebufferEXT'
getProcAddress: Unable to resolve 'glBindBuffer'
getProcAddress: Unable to resolve 'glBindBufferOES'
getProcAddress: Unable to resolve 'glBindBufferARB'
getProcAddress: Unable to resolve 'glBindBufferEXT'
getProcAddress: Unable to resolve 'glBindBuffer'
getProcAddress: Unable to resolve 'glBindBufferOES'
getProcAddress: Unable to resolve 'glBindBufferARB'
getProcAddress: Unable to resolve 'glBindBufferEXT'
getProcAddress: Unable to resolve 'glDeleteBuffers'
getProcAddress: Unable to resolve 'glDeleteBuffersOES'
getProcAddress: Unable to resolve 'glDeleteBuffersARB'
getProcAddress: Unable to resolve 'glDeleteBuffersEXT'
qml代码如下：其实就只是新建的项目而已。我都没写任何代码捏。import QtQuick 2.2import QtQuick.Window 2.1
Window { visible: true width: 360 height: 360
MouseArea { anchors.fill: parent onClicked: { Qt.quit(); } }
Text { text: qsTr("Hello World") anchors.centerIn: parent }}
