18 months old with no issues until the last week when it began randomly not posting. I power on from hot or cold, the fans spin and the LED's all light up and stay lit, HDD light is on and stays lit, thats it, monitor doesn't turn on, no beeps no nothing. I have to hold power switch to power down.
I have flashed to latest F11 bios but still get the same problem.
I have run memtest, windows 7 memory diagnostics, tried with 1 stick at a time, still the same.
I have tried a different graphics card, booting with nothing plugged in, the lot. The fact it is random and I get no beeps makes it kinda hard to pinpoint but I am leaning towards the motherboard. Does anyone have any thoughts on this? I am no expert but try to fault find logically but intermittent ones are a mare
