ECS EliteGroup motherboard restarts rapidly

I just got my friend a ECS 865G-M v5.0
It restarts over and over when the computer seems to have been running for 5 seconds. I think it is restarting because the motherboard sound thing makes a small click every 5 seconds. I have a 3.0 Prescott on it with a stock heatsink. I thought it was the RAM (2x512mb Patriot pc3200), but i tried one stick of Corsair Value Select RAM (256mb) and it did the same thing. I am using the Antec Aria 300w power supply. I unplugged everything that could have been a problem and i was left with just running the motherboard, cpu, and RAM. It still does this. Do i have a hardware conflict?

Have you tried another power supply? Perhaps, the PS rails are too low and the mainboard is resetting.

It might just be a bad board. I have had several problems with those ECS motherboards. I know fry's gives them away alot with a CPU combo, but they don't seem to be of the best quality. Maybe try returning the board for a new one.

ECS boards are trash. We bought a rash of them a couple years ago. Roughly 50% of them are sitting dead in a box right next to me.

That said...

Despite my desire to just blame the board for this and be done with it...it might be a PSU problem.

I just posted a similiar comment about ECS. I have two of them pt800ce-a. I got them on the frys deal but hey the price was cheaper than I could get just the processor for. I have one that won't boot at all and one does the reboot thing and if you start any game it gives you a general protection fault. I have tried everything because I built the system for a friend. I used an abit max 2 on mine thats how I ended up having two of the ecs boards.

I swapped out video cards and even out the whole system in my case to check the power supply. Then I took the processor out of the ecs and into my max 2 to check it and it worked fine. I think the boards are just not very good.

LIke I mentioned the first one reboots and gives errors.
The 2nd one I tried rebooted once and would not even turn back on.
