Having problems with your HP PC Desktops ?

I have HP 305W. When turns on the power, it stops within 5 scnds

\015 I have HP 305W. When turns on the power, it goes up for few seconds and it stops except power supply fan which means CPU fan stops and disk reading stops. Sometimes the floppy disk reads but not at the subsequent tries on power on-off. I have checked HD at other computer and works well. I have even replaced RAM with other good RAM card(PC3200 512RAM). It has same problem. When power is on, it reads floppy disk and HD begins to read. Within 5 seconds HD stops and CPU fan stops. A green light at the back of computer is still on but flushing slowly. Please advise.\015
