Hi, Earlier I was having the issue when the windows XP used to crash as soon as I login to windows. Then I removed the delprot.sys file from the drivers dir. Now I am getting the issue that when I go onto the internet explorer, the windows crashes with error 0XC5, 0XA. I uninstalled the windows xp hotfixes SP2, but the issue does not go. Any pointers would be helpful ------------------------------------------------------------------------------- !. Was everything ok before you installed sp2? I did not install the SP2. It was justthat in Add remove program, I saw some hotfixes with the SP2 --> Which I removed after I started getting the problem. @. Have you made any hardware changes lately? Naah. I did not. The problem started happening on thruesay while I was in the office. #. Any new software installed or uninstalled? I did install an application something like VLC player that plays .bin video files on 18th Dec. But I saw the error on 23rd Dec. I have uninstalled the software today but the issue is stll there. $. Do you have updated virus protection? Yeah, I am using the Symantec antivirus version 22nd Dec Right now I am running sfc /scannow. Since it is very slow, I am waiting for the results
