Nineteen long days (19 days, 16 hours, 36 minutes, and 33 seconds to be exact) after I had started my Windows XP Professional Stress Test, my PC finally required a reboot.

As you may see on the screenshot above, there's an infotext that says "Contains letters, .." and it seems that it just wont go out of my screen. I tried refreshing the screen, but still that yellow info bar is still there.

So, I had no choice but to reboot the computer, thus ending my own Windows XP Stress Test, hours before the 20th hour mark.
