Why does my computer briefly start and then shut down repeatedly without displaying anything on the screen?

Accepted Answer

This behavior (brief startup followed by repeated shutdowns without video signal) usually indicates a communication failure between the motherboard and critical components. Here are the checks to perform in order:

1. Check the power connectors

Unplug and then firmly reconnect the 24-pin ATX connector (main power) at the back of the motherboard
Also check the two 8+8 pin CPU power connectors (top left of the board) - they must be properly seated

2. Test each RAM stick individually

One DDR3 stick at a time in the first slot (the one closest to the processor)
Ensure that each stick clicks securely into the notches at each end of the slot
If a stick causes repeated shutdowns, it is defective

3. Reset the BIOS (CMOS reset)

Completely turn off the computer and unplug it
Locate the CR2032 battery on the motherboard (round button battery)
Remove the battery for 30 seconds to reset the BIOS
Reinstall the battery and reconnect the power

If the problem persists after these steps, you can also use the JBAT1 jumper on the board to reset the CMOS when the system is off.
