Check the cpu fan and fins are clean if you have to take processor out make sure you reapply thermal compound, Also check the ram is seated correctly.Also check the psu is functioning correctly as it could be a faulty psu . Good luck John

several things could cause this problem your power cord may not be supplying enough voltage or amperage or both. the ram could have been compromised or the hard drive may not be initializing. i would look at the motherboard last. illiminate the easy stuff first. check voltage level on your ac power supply. try different ram open the hard drive bay and make sure it is comming up to speed.
certain thing happen in a given order during the boot process. the bios loads so the start up starts it loads to the ram and bring the hard drive up then video. your unit is stopping in the very beginning of these steps. follow these steps to isolate the cause.
