Hey all, I'm new here I am using Compaq CQ Series notebook. I just copy some data from CD/DVD room a couple days ago, and next day when i start up my computer, there is eternal loading bar windows screen. I have try some effort to fix this : 1. I select "Last Known Good Configuration", and still stuck at loading screen windows 2. I select "Safe Mode", and stuck at crcdisk.sys 3. I proceeded to reinstall the windows from Vista CD who come with the laptop but it won't running 4. I try to install from USB port and select F9 before windows loading bar, and choose the my USB name in "Please Select Boot Device", and the screen show "Error, Press Any Key to Continue" Now I cannot boot my com. The booting always gets stuck at the loading screen, where the green bar keeps moving. Any one have any idea that I have not tried to fix this problem?
