Internet Explorer may keep crashing because it is not in compatibility mode, it has a virus infection, multiple temporary files are being stored, its tracking option is off or its hardware acceleration is on. Sometimes, the crash may occur because of low system specifications, including low memory or overheating.
Turning on the tracking option and running a virus scan may help in getting rid of the problem. A user should also ensure the computer has sufficient memory to allow easy loading of various Internet pages. It is equally important to ensure that the computer is well ventilated, since overheating may cause the system to keep shutting down.
