Here are a few steps we can try to identify, troubleshoot or resolve the problem.
Way1: It may be because the "Temporary Internet Files" folder is corrupted. Simply emptying it does not fix this issue, it needs to be "moved" from our computer(we can find "Temporary Internet Files" by the following screenshot). It does not reboot the computer, but it does log off the user.
Way2: I find when the temporary IE files have reached capacity of the settings set for IE. Maybe we can not download and pages may not open either try deleting your temp files and history.
Click the gear top right and delete browsing.
Click the internet options.
In the homepage clear that and type in about blank then at the bottom apply do not use the other's like "Use Current" or "Use default".
On the general Tab>tick to delete browsing history on exit, if you do not mind deleting them manually do not change that.
Next to that is Settings> Disk Space to use maybe set at 250 megs I have mine at 330 megs to cover some of the downloads as they maybe big(we can set it as several hundreds). If you have plenty of HDD space add more if you download big files then empty your cache.
