I brought my computer box back to Greece by plane taking with me only the hard drives. When I reconnected the hard drives and I booted the pc, it couldn't load anything. It reads the ide connections and then reboots. Sometimes, the screen with the start up options (safe, normal etc.) is appeared but when I select normal startup, it reboots again. When I try the safe mode the system reboots when it loads the "mup.sys". I used the XP CD but it cannot even 'read' it. With the milllenium start-up disk, when I select any of the options the pc reboots. After the reboot, most times all the leds work together, but the screen is on the stand-by mode and i have to switch the power supply off( reboot button doesn't work).A few days before I sent the pc, when it was switched it on it stopped responding after the ide screen( only the green led on) and I had to reboot it twice (!) before I saw the 'start up mode' screen and selected the normal startup and then it was working properly!
