Hi everyone, this is my first post in this forum. I am having some problem with my laptop from a few days and most frustratingly i am unable to pin point the source of the problem. Some times the application starts very slowly. some times the application stops working with out any cause. etc. I guess some virus related problem might be the cause. Even right now the start button in windows 10 is not working. Even if i click it nothing happens. Please i need some help to solve all this problem or at least to pin point the causes of this problems.
With regards
Lakhi
PS: i am using sony vaio laptop E series with 6 GB RAM, Core i3 processor, 64 bit windows 10. Avast antivirus.
Edited to add: Now when i restart the laptop i am getting a crittical error massage “Start menu and cortana are not working. We will try to fix it next time you sign in”. Howeveer, the problem is not fixed in the next sign in. The massage could not be removed and firefox has now stopped working.
