While installing xp in the middle the system was hanging and display blue screen

For most hp Compaq laptop, when installing Win XP resulting in Blue Screen Of Death (BOSD)

Take note** Reset your Bios setting,
"Disable" ->SATA Native Support -> save & exit

Then install WinXP.

Hope it helps.

do you have a usb drive plugged in? or any device like wireless keyboard/mouse adaptor? unplug everything and only leave a wired keyboard and a wired mouse.

If where is blue screen while you install your operating system, it may be a hardware failure.

Hi,
You have told that blue screen comes only if you connect your nvidia display/graphics card. Usually Blue screen comes if there is some problem with the hardware or due to incompactible hardware drivers. Remove the nvidia card from you system. Reinstall your system and then install all the drivers present in your motherboard cd. After that go to nvidia website, download the latest driver for your nvidia display/graphics card driver. Now connect your nvidia hardware back to your motherboard. Before that clean the dust particles present in the motherboard connecting terminals, if any. Now boot your system into safe mode. Restart your system into normal mode, install the latest driver downloaded for your nvidia hardware. Now everything should work fine. If you get bluescreen again, remove the card from system, restart into safe mode, uninstall the driver. Check the hardware in someother system, to detect wheather the problem is with your nvidia card or not. I hope this will help you out.

You can try also to do reformat your hard drive as fresh unallocated one before doing formatting again to install windows. And check your installation disk for scratches.

The Blue Screen of Death (also known as a stop error, BSOD, bluescreen, or Blue Screen of Doom) is an error screen displayed by some operating systems, most notably Microsoft Windows, after encountering a critical system error which can cause the system to shut down, to prevent damage.
Bluescreens on NT-based Windows systems can be caused by poorly written device drivers or malfunctioning hardware. In the Win9x era, incompatible DLLs or bugs in the kernel of the operating system could also cause bluescreens.
Bluescreens can also be caused by physical faults such as faulty memory, power supply issues, overheating of components, or hardware running beyond its specification limits. Bluescreens have been present in all Windows-based operating systems since Windows 3.1; earlier, OS/2 and MS-DOS suffered the Black Screen of Death, and early builds of Windows Vista displayed the Red Screen of Death after a boot loader error.

I hope it helps!!!

try running a check disk utility on them to see if this fixes the problem, if not then your copy of XP is either flawed/invalid, or is missing some very crucial installation files
