Sounds like a faulty screen or the connector.

The laptop keyboard will need to be replaced, go to www.ebay.com type make and model of laptop, refine search to keyboard.

Before Windows boots, determine which keyboard command you need to type to enter the "setup" or BIOS. Hit that key and it should get you into the BIOS. Once in the BIOS, go to the boot priority settings and set the DVD to boot first. Normally the harddrive is first.

You simply insert the card in, and it will click into place to get it out again, push it in again, and it will "Unlatch" and pop out. Just make sure you are in the correct slot.

You should be able to connect using vga if the TV has a vga input. Once it is hooked up you can toggle the display using the key combination fn+f5.

Hi shaikh_shaha

Can you get it to boot using any of the options it gives other than boot normally? If the blue screen is caused by hardware then installing xp will still present the problem. If the blue screen is an operating system crash then using the recovery disk or doing a repair install will solve the boot problem.

If you still rather install xp then you need to go into BIOS and set 1st boot device as CD. To go into BIOS you will need to press F10 or F2 (usually) as displayed on the splash screen when you power on

Does this help?
