Hi Vaz, definitely try what 123 says. Also Windows XP says it needs at least a 300 MHz CPU.
Also go into the bios, and see if it has a boot anti virus setting, if so turn it off. As 123 was saying windows XP needs to change the boot track, and that setting may stop it. If you do get windows XP installed, then go back and turn the boot protection back on. If you are still having problems, it could be a problem with the hard drive. Go to the company that made the hard drive web site, a lot of them have diagnostic software to test the hard drive.
