All the time krasitsja cookies, what could be the reason?

Is there a web application written in ASP.NET MVC, I use them about 50 people, no one complains. Except for one thing. He has all the time broken cookies have to approach it, clean the cookies and temporary files for a short time, the program is working fine then again.

Sinned on a lack of free disk space, but it 20GB.
What else could it be? Virus?
What can I do? Windu reinstalled?

About other browsers can not say anything, everything is forcibly sitting on the Edge IE.

As version - the Problem might not just be in the space, but the fact that his account does not have rights to write for some reason. For example, the admin had come up with storage cook in an unexpected place, but a particular user doesn't have write permissions. But I need details. What condition must be cookies, which can find.
