I just see that cmos battery is missing ! maybe (should be) the culprit.

Don't think that is an issue, the seller of the rig has a picture with a green light on the sata drive and no battery and is running fine. I also found out i had to put in all of the power connectors, done that and found out the real Power SW, done that as well. Same result, no signal! Driving me insane just for a product to "add GPUs." Which i expected to be done in 5 minutes, not 5 weeks.

Thanks all for your help, if worse comes to the worse, there's a PC repair shop just round the corner, I'd probably get in there, and see if they can fix it if this board can't. Worth a go myself, before getting a new item fixed! hahah

If I had this problem I would do the following:

1. Determine if motherboard posts - use a plug in anaylizer already suggested and resolve the fault it shows if possible which could be as simple moving RAM around and even making sure all chips are seated correctly.

2. Determine if the psu is working correct so with system on carefully use a dc voltmeter to check cpu power connector at the mobo end and 24 pin atx power or simply get a good known psu to test the mobo with and even then check the voltages as a mobo fault could pull down voltages.

If power is present and correct values measured and reaching the mobo and its not a RAM problem preventing post where noting else is connected to the mobo then you have ether a damaged mobo or damaged cpu and remotely possible corrupt cmos or bios chip. To rule out CPU fault try a known good working cpu to test being mindful the mobo could be eating cpu's due to a mobo fault and if suspected try measuring the power connectors into the mobo without cpu installed as every clue at this stage helps. If you really want to get into fixing it then a usb chip programmer to read the bios chip and verify its contents are correct. also measure the voltage at the bios chip to rule out that problem. happy hunting and remeber if you can do no good then do no harm lol.
