Bootup problems

Hi everyone. So I just picked up a new motherboard (ASRock K10N78D) installed windows 7 x64 and it all worked fine. Now I was getting everything setup and rebooted and it gets stuck on the windows loading screen. So I tried reinstalling windows 7 x64 like a billion different ways and still no go. But now I get all the way to the "Setup is running Windows for the first time" screen then about 4 seconds into it, it reboots my computer completely then continues in an infinite loop. Like I said it worked good for about 1hr but after rebooting, nothing.

Ive tried
Shorting CMOS jumper.
Removing the CMOS battery.
flashing to every other bios available.
booting in safe mode (but errors saying windows first time setup needs to run out of safe mode)
Swapping around my 2x2GB modules to see if memory is dead.
I installed a new main IDE hard drive, I even tried changing the IDE cable.
I tried unplugging all the unneeded components.
I tried removing the disc when I boot into the part where it reboots.
I also have the fourth unlocked but tried disabling it, but no difference.

Windows 7 x64
ASRock K10N78D - bios#1.80
AMD Phenom II X3 710
Kingston hyperX DDR2
Cooler Master 550w

anyone have any ideas? I could really use the help.

if your using a ide drive did you set the jumper to master? do you have the ide cable pluged in right? should
be motherboard / master / slave.

hope that helps

Yea the jumper is set to master, ive tried different cables. Before I had the double ide cable now im using a single just to verify its not a cable issue. Thanks for the reply

Yea I checked the ATX, I was thinking the same thing. The temps are at like 35c

not sure what else you can do ..... sorry
maybe it's the motherboard . can you put the old board back in and see if it works with it.
if it works with the old board sent the new board back for replacement...

Hey guys thank you so much for the responses, I was also thinking about putting the board RMA status aswell. What id do for a simple dvi to vga adapter lol, ive been using hdmi for years now didnt think id need them. I am going to my moms house for Christmas and I know I have a gang load of them there with a couple smaller monitors so I guess ill just take my pc with me. I hope newegg has a 30day return policy I recieved it monday so...

You know what im going to try something, when I first got the board in I already had Windows installed from the previous board (gigabyte). Well when I installed it I just wanted to see if itd boot and sure enough it did I wonder if I install windows with the old mobo then just swap em out if itd keep working or goof out.
