I was having windows error messages popup everytime I opened an executable or anything in internet explorer (it would go to my homepage but close on every link). I could not even open virusscan without getting some kind of error. I read up online and learned SFC /SCANNOW might work. I did that an it looked like everything went well. I tried opening applications and browsing the internet again and this time I was not getting error messages. I restarted my computer but now I get to the black Microsoft Windows XP screen and it just freezes. I cannot boot to last good configuration or safe mood. I disabled restart on system failure and tried restarting again and I got to a blue screen saying "A problem has been detected and windows has been shut down to prevent damage to your computer. PAGE_FAULT_IN_NONPAGED_AREA" I'm assuming this was because of SFC... Any ideas how to fix this?
