Please check out whether the problem you are experiencing is not coming from its graphic card or motherboard. Also, indicate whether there is any beep while you try to turn on the computer.
there is no sound at all. just blank dark screen. i checked drives to make sure no cd's memory cards or anythng in system. tried external monitor and also removed battery for a couple days. same. just seems like it reboots about every 25-30 seconds. led's flick on/off and cd lites then hdd lites then again in 25-30 sec.
