Aaargh! Stuck in boot loop on GA-Z68AP-D3

Help!!!

Some of you may remember, I built my mum's rig a couple of weeks ago. After a brief worry re: PSU, it was up and running (thought PSU was dead, tried another one for a couple of days which worked fine and when I eventually swapped back to the original one it seemed to work also... and yes, I had connected the 4-pin!)

Win7 installed, the usual updates and MSOffice install. Everything running fine. Basic rig: i3 2100, mobo as per title, WD Caviar Blue 500GB, 4GB Kingston RAM and a cheap Radeon 6450 to provide VGA output. Not a fancy machine but plenty of upgradeability should the time come.

I'm about to head down to hers tomorrow to take down the fully working computer and I decide to check all the BIOS settings to make sure I haven't 4rsed anything up. I decide to swap the boot order to make the DVD the first option (even though there isn't one) just in case we add one later... don't ask me why I did it, but I did.

After doing this and restarting the thing goes into a boot loop. Power on spins the fans and lights the Phase LEDs for maybe a second or two and then power down. Repeat ad infinitum.

So, I've tried: removing everything which isn't essential (CPU and one stick of ram) - that means no HD, no video card. I've tried locating the RAM in random sockets. I've taken out the CMOS battery for 1 min. I've tripped the CLR_CMOS jumper. I've taken the power cord out for 30 mins.

Nothing seems to shake this damn thing out of its boot loop.

I don't have a case speaker so can't check for any diagnostic beeps but HELP!

Any clues?? Is it a case of new mobo from OCUK? I'm probably not their best friend as I RMAed the PSU but just before posting it back decided to have one last go and found it worked...

Any help much appreciated: I've done the usual google and it seems these mobos have a bit of a rep for boot looping but usually after OCing or BIOS flashing - I've done neither.
 
horrorwood... thanks for the tip. Sadly it didn't work for me so I'm guessing I have a defunct mobo. For some reason I ordered it from another supplier (golden rule: always buy from OCUK :D) so I'll be RMAing it back to them. Fortunately I've found a shop en-route in Lincoln which has one Z68AP-D3 in stock so I'll be collecting that on my way down tomorrow...

I just hope it is the mobo which has died (and hasn't taken anything else with it) otherwise I'll be £90 out of pocket and still need to replace either the CPU or RAM...

I don't get why the CPU or RAM would have fried though... but then I'm not particularly sure why the mobo has given up the ghost either (if it is indeed that)?? :confused:
 
Well, thanks for the pointers everyone... replaced motherboard with the same model (but might be a slightly different revision - perhaps newer?) and it's all working.

Haven't a clue what happened to the old one: maybe just a glitch in which case I'm glad it died while I was still in custody of it rather than mum.

New one seems to be working well, although the usual problem with hibernation/sleep in Win7 so I think I'll just recommend not to use that. It's a shame as it boots back up from a powerdown in about 0.5s using that, rather than the 10-15s normally. I'm sure my mum can wait those extra 10s, though...

Cheers again and glad I wasn't missing anything obvious... just trying to use a dead mobo.
