Hi

i would be tempted to take the hard drive out from the laptop while switched off

then put it back in again
i have know this to help before on several occasions

its normally in a compartment on the bottom of the laptop with just a couple of screws to remove

Hi there !

Blue screen means that your hard disk drive is damaged and cannot be repair or reformat. But still to repair or run windows operating installation on your CDROM and maybe it is repairable. Other you need to replace your hard disk drive to work again your computer.

Good Luck.

Isolate where the problem is: it could be the LCD display or the graphics circuit on the main board. Connect the VGA output of the laptop to an external monitor - one that you know is good. From the function keys, activate the VGA output of the laptop - it's suppose to switch between the LCD display or to the external monitor. Switch it to the external monitor. If the external monitor works, then you have a problem with the LCD display of the laptop.

If you are using vista, try using startup repair
If you are using xp, try repair your pc using a cd

"hope it helps"

you may need to restore the computer. any questions you can email me at [email protected]

First conclusion: This is not a software fixable problem. If your notebook is still in warranty, I suggest you to RMA it. No doubt somethings broken.

hi...some times norton uninstallations create this problem, in which norton also uninstalls some system file like virtual driver file, etc.! u can try these things :

1. use systen restore to restore ur previous settings

2. IF it don't works, reinstall window !

let me know if it helps....

It sounds like your having motherboard problems. Did you change the bios driver at some point?

basing on the information you have given here are the possible solutions:
remove any external device connected to your system (printer, external hard drive and others) if removing this does not work and still gets a blank screen with blinking cursor try to go to safe mode with networking. if successful try to download the driver for your video adapter.

when you try to start the computer , do get anything on the screen like a logo? when does the blank screen occurs, is it during the turning ON of the computer or during the windows xp logo appears on the screen?

a blank screen could be caused by the following: defective video adapter, corrupted video driver, defective memory, unknown device causing the issue like the hard drive, optical drive or other peripheral installed inside the computer.

try also using an external monitor
