Can't install any operating system on desktop

[Jowin]

My desktop Pc was getting slower and slower a so I decided to format it and reinstall windows in it but the windows install ended with an error then I tried to install other OS like ubuntu, linux mint , open suse , cent OS but all the installations ended with the computer installing the OS for a very long time and me switching the PC off. Then I thought that there could be something wrong with the hard drive so I thought I would use the PC by booting with an OS installed in usb drive. I am able to install some OS in the usb drive by using Lilo and able to run it in live move but when I boot in persistence mode with the USB drive the computer doesn't start What could be wrong with any of the hard ware in the system and how can I use my Pc?

.net drivers and other .net stuff not installed and it restarted and even the next time the setup runs it still ends with same error (windows xp)
