I have received the "STOP: c000021a (Fatal System Error)" Error!  I am very stressed right now. I own a Compaq equipped with Windows Vista (Home edition I think?) I was using the internet when my browser crashed, and when I went to send in the report for the crashed browser, it failed. And my computer started acting very slow. I tried a few things, but got fed up with the snail like pace, and just turned the computer off. When I turned it back on, I got the screen where I pressed, "Start Windows Normally," and when I did this, it went to a blue screen and started to "Repair" the system, and said it could take over an hour... I am thinking this whole time that I have a horrible virus. So in thinking that my computer was being searched and destroyed during this "Repair" operation, I turned the computer off and back on again. This time, it brought me to the blue error screen saying "STOP: c000021a (Fatal System Error)" Error!.... I am not a computer expert, so I will not understand all the complex computer lingo out there. What can be done to fix this problem? Someone please help!!
