I stopped using my computer for a week.
The week before that my computer was perfectly fine.
I turned my computer on and it starts to show weird problems.
Problems: i can't open any games/apps on my pc.
If i clicked on epic games for example, it will open 30 minutes later. But it just stays there.\
And i can't dowload anything either.
i tried scanning virus and it said there is no threats.
and the one thing i found that is weird is my disk always runs at 50%. it was not like this before.
