Hello i'm disperate pls help me ... i have an ecs 755 a2 motherboard and the leds and pwr button don't work it's starts but nothing appears on the screen and when i try to turnit off the button dont work pls help me....:((
Make sure you have the correct front panel header connected correctly to the case wires. Open you're manual to page 12 under the English section. There you'll find a picture of the front panel header & how to connect the case's LED's to the motherboard.
If you no longer have the manual you can download it from ECS at this link.
Chances are you may have the wire's connect backwards. (Positive + connected to the negative - ECT).
Example, pin 1 is the + for hard disk drive & pin 3 is - for the hard disk drive. Cases vary on wire colors, normally if each connector has a common colored wire (solid color) that common wire would be the negative. Stripped wires are negative. Other cases use white colored wires as negative & colored wires as positive. As far as you not receiving any display. Try removing the AGP card & clean the copper contacts. Clean with alcohol.
Place a couple drops onto a cotton swab & clean the copper, both sides. Blow out the AGP slot with canned air. Re-check all connections, power & data cables before closing the case. Power on the system & check the front led's for operation.
If you still fail to get display, re-check the connection from the monitor to the case. Try you're monitor on another system. If good than you're video card could be bad. You're motherboard can run an 8x/4x speed AGP 1.5volt (only) graphics card.
Good luck zeratu_l !
