You're lucky yours warns you. My last PC was satan in a metal case. Any warning message I got, never really showed up as even the process of telling me something was wrong was enough to cause it to freeze. It also had the bad habit of rejecting everything I tried to upgrade and ruin it so I couldn't return it. How, it did it, I will never know, but it melted a hole in my motherboard but managed to work for 3 more days until I could save my data from the faulty hard drive before it finally died.
