Winxp setup fails in the begining

Try another CD/DVD Drive to read you Bootable Disc.Usually its something have a problem reading on CD/DVD Drive.

check the capacitor componen on mainboard if any wrong repair it, this problem is because some voltage is down

first i would check the disk to see if there is any dirt or finger prints on it .. i usually wash them with liquid dish washing soap and cool water ..then handle it by the edge ... CDs can be pretty dirty and still work for music because they use an elaborate error correction system .. you can have thousands of errors and it will still sound fine .. data, like your instalation disk also has some error correction but you have to end up with a perfect result ... a little glitch in music may not even be noticed but on a data disk an uncorrected glitch could cause lots of trouble .. you could have a bad disk .. you could check it on another computer but of course dont let it install.
if the disk is good and you are still having trouble then you might reset CMOS to either safe values or optimized values .. if you dont know how to do that you can repost ..

just tried to reformat your hard drive and then
install the windows XP
