Help! I own a PC with Windows XP and it keeps crashing. Actually yesterday it kept crashing and today it kept on freezing and I had to take out the battery to reboot and when I did a blue screen, as did yesterday, keeps showing up. The blue screen just flashes and all I can read is that there was a system error. Then a black screen states that it shut down to prevent from further corruption. Also, it has the option of starting in safe mode, last config, or startup normally. It will only boot up when I click last config. However, if I open Mozilla Firefox, the latest version, which I usually use, it crashes after a short period of time. It sends an error report and restarts. So far Firefox lasted and I am typing to you now. What do I do? I downloaded Registry Easy and scanned it once. I tried again for a second scan after successfully completing it one time and it froze, which led me to start up again. Help!!!! I have alot of important files on this computer. Also, I can not open Internet Explorer without a dialogue box showing. Microsoft Windows opened a tutorial: However, I can not open the Windows Update. Even in Firefox, when I click on Windows update the tab that opens is an Internet Explorer one.
