Hi All,

My system has been running fine for about 6 months and then this morning it will not boot. The lights go on, the fans run but there is no bios beep and nothing on the screen.

First reset CMOS and see if that gets any life out of it.

Next strip to bare essentials system and see if you can get to the BIOS screen.
Just min RAM, video, keyboard.
All drives should be disconnected [power and data], all add-in cards removed [except video if you don't have on-board], and all USB devices disconnected [except keyboard if applicable], speakers disconnected.
- If you can get to the BIOS screen then something you took out was bad.
- If you can't then it's Mobo, CPU, RAM, or PSU and so need to figure out which of those.

sorry if i repeat some,
the fans running indicate 12 V present - no bios beep means nothing running
Here my troubleshooting procedure :
clean the system from dust, then  test with the minimum setup - disconnect also all peripherals and network cables :
motherboard + cpu + 1 ram stick, video card, power supply
verify that the 4-pin cpu Aux power plug is connected
on boot, do you have a display?
if NO it is one of the connected, swap ram, Power supply, video card or monitor - leaving only motherboard and cpu
if Yes, add devices till the problem shows

you can also check the motherboard for bad capacitors as shown here :   www.badcaps.net

thanks for your replies guys but i decided to return the motherboard for warranty.

the gigabyte support said other MB owners experienced similar problems.

I will let you know how that process goes. My supplier said it shouldnt take longer than a week or 2

thanks again
