One video driver issue is that Lenovo is very conservative with their video driver updates. My current desktop has a NVidia T1000 8GB card and Lenovo's supplied driver is about 4 months older than the conservative driver from NVidia's site. Before that update was added to Lenovo's site, they were about 9 months behind NVidia's conservative driver.

Though the portable version of calibre working and multiple programs being unable to open ePub files suggests something in your Windows setup and not a driver issue.
