Hey guys, so yeah the PC plays up once again. This is it doesnt turn on when i press the power button (PC on button thinghy). I press it like 20+ times then it mite turn on, if not what i do is unplug the PC from the power point and plug back in and then it turns on with 1 press.

So what do you guys reckon could be the cause of this?

It could also be one of your daughter boards (modem network sound) I have seen that happen.

My wife's system would lock up and then not boot not even the BIOS if I unplugged and repluged it then it would boot.
In the end it was her sound card but I had already tried the psu, ram, nic card, modem.
As soon as I removed the sound card the system loaded to the desktop.

Sometimes it's just a process of elimination :shock:

this is buggered....umm so with the PSU, i onli have a spare 380w one, so thats gonna not be enough to test out this current PC.....um is there a way to figure out ( scan or something ) the status of the mobo and to sorta predict when its gonna die?

Sorry but I am not aware of any way to test a motherboard for future failure.

Motherboards are tested twice during manufacturing.
The first time is before the board is populated with components this is a point to point test done on a bed of nails tester.
This is to insure that all connection points have no short or opens throughout all the layers.
The connection points are derived from a "net list" generated from the board's schematic.

The next test is after the board is populated with components.
This test involves putting test leads on all connectors on the board and reading all outputs after power is applied.
Some manufactures will also test their boards using a range of volts and amps to simulate real world usage.

Now all of this is not to say your motherboard is going bad Gigabyte makes a good product I doubt it's you MB.

Doesn't the Antec PSU have a rocker power switch on the back of it?
What happens if you just use the switch to turn of the power and then back on?

Ok, re-do.....
Yes Antec have them switchs at the back and i tried just before, i can just switch that off and back on and PC will start. So no need to pull out the power plug and plug it in again.

Would changing something to do with the ummm BIOS or CMOS or any of that stuff do something?

ahh yes, righto. So it would be something with the mobo or PSU as you said earlier.....coz its like im power cycling or reseting some sensor like u said in order to get it to turn on. **sighs**
