New ECS K7S5A in reboot loop

[gpupurs]

I have a new ECS K7S5a motherboard, Duron 750, and Enlight 300W power supply. Just put it together, on boot up, it gets past CMOS POST, polls all the drives and identifies them, and then reboots. Over and over.

I disconnected all drives, same thing. Swapped the ATI Xpert 2000 Pro AGP card for a ten year old Trident PCI video card. Same thing.

Occasionally it doesnt even make it to poll the drives before rebooting. I was able to DEL into the BIOS setup once or twice, but it rebooted while I was checking the settings.

Ideas?

I had a similar problem, because the video card didn't seat right. Another thing that you might want to look at is the memory, the board is very picky on the memory that you use.

Good Luck.

An update. It seems my problem might be a buggy power supply. While I said I had disconnected the drives, I had only yanked the IDE cable, the power was still going to the drives. I'm able to get it to sometimes boot and begin loading Windows with just the hard drive, floppy, and DVD (no CDRW or case fan). But it's still unstable. It was sitting at an install prompt, just waiting for me to walk back over to it (ie, doing nothing at all), when it rebooted, and began the reboot/reboot loop again. So it seems marginal.

I'm a bit upset, this is supposed to be a budget box, I bought the Enlight 7237 from TCWO because it's a good case for the price, and it included a 300W Enlight power supply and case fan, so I thought I'd be safe for an unclocked Duron 750 system.

But it seems I'm wrong and the power supply is just as much junk as the no-namers. What pisses me off is that it looks like the price of the computer is going to go up 10-15% just to replace the PS to appease a $65 motherboard!

This PS is an Enlight HPC-300-001, BTW. It's specs are +5V:25A, +3.3V:20A, 165W combined power (which sounds low). Is anyone successfully running an ECS K7S5A with this PS? Just wondering if it's defective and I should try to RMA it with TCWO?

I've also got a spare MS-6309; would that work better with this PS? Would I be better off getting a CPU for that board and trying to find a case/PS that's proven with the K7S5A?

Is there anyway to see what kind of temps you are running on that thing? Are you trying to overclock? Make sure your mb settings are correct. What does the bios recognize your cpu as? unhook everything except cpu/fan, video, and memory. Does it complete the boot now?
