Obviously, the most convenient way to downgrade is to do so without reformatting. In order to do that, you need to have a real retail CD of Windows XP. If all you have is a recovery disk that came with your computer, you’re not going to be able to do it this way. You will need to reformat.
To downgrade, use the following as a guide:

1. Do a full backup of your current, Vista system. If something happens, you can always revert to the backup.
2. Boot your computer off the Windows XP disc. Just pop the CD into the CD-ROM and reboot. If, for some reason, your computer boots without looking for the CD drive, you need to go into your system BIOS and change the boot order so that it checks for the CD drive during the boot process.
3. When the computer asks to press the space bar to boot from the CD, do so.
4. When Windows XP Setup starts up, press “R” to enter the recovery.
5. If it asks you to choose a Windows installation, press a number and hit Enter. The likely number will be 1.
6. If you get asked for an Administrator password, enter when asked. If you do not know it, you will need to abort and go back into Windows Vista to get your password.
7. At the command prompt, we’re going to use the “fixboot” command. We’ll use the following commands in sequence to prep for XP:
fixboot
fixmbr
cd \
ren windows winvista
exit

Possible that PC is hanging up as there is fault on the OS ( operating system) or a virus in the OS. Also connect aan external monitor to confirm if the PC is working or there is a fault in the display section or LCD. If so the linking cord to the display or the power supply or drive can be faulty. check the battery voltage, check the adaptor voltage on the terminal.

Also it is possible that the back up( CMOS) has low voltage or the memory card is a suspect. In this case you need to check the voltage and also try and swap a memory card. If not the OS is a suspect.

If there is no response but the PC tends to work slower and occasionally hanging when a program is being executed then you might have to install the OS once again. Install the OS and then an antivirus before the drivers of the PC is installed.

Thank You for using Fixya
