Windows 7: New i7 build cycles on and off?

Hi folks I need your wisdom. I just built a i7 3770 build using my new case, old 1050 PSU and a new to me single Diamond 6870 GPU. I took my time and really labored over the install. I even went out and got a new Thermaltake 240 sealed cpu water cooler system set up on it. When I turn the unit on all the MSI P67A-GD80 leds light up and my fans spin, my new DVD and Blu-Ray cycle on and all my accessories power up but then about every 5-10 seconds it will cycle off and then attempt to power up in a loop. Does anyone have an idea what's up. Can't get to bios and from what I can tell all the leds are telling me system is fine. I thought maybe because this board comes with a 8 pin CPU plug and a 6 pin GPU plug which I hadn't hooked up that I would run the 6 pin cable and that would be it, but no it's not it. Dbl. checked all connections twice and then looked extra hard at the connections for the power,led,hdd,restart headers and they all appear to be fine. I'm sure it's something simple but could really use your input !

Hum odd you can't get to the BIOS linne is the board UEFI or the old sort?

Have you tried all the usual F keys or DEL for the BIOS?

It's a new old board and it cycles too fast to get to a screen. Tried tapping delete but no joy.

Hum looking at a Google for that board -

I would try reseating the RAM, try swapping the sticks round as well. Then it might be a good idea to remove all of your PCI connections and slowly add them one by one seeing if the computer boots

That's my AMD spec's the MSI board in question is the :
MSI USA ? Mainboard - P67A-GD80 (B3)

Tom982,
Good idea, I also see some have simply cleared the CMOS. I will pull all ram sticks but one as well. This may have to wait till Sunday as I'm gassed after starting at 6:00am today. It least my old AMD 8 core is back up and running in it's new Corsair case!

Sounds like a power supply issue, either it is faulty or it is loaded so it shuts down. Suggest you try another one to rule that out, then strip system back to basics and see if it boots.

Alan, if the ram swap does not work, try using another GPU (which I know you have several). If that does not work, remove everything except what is absolutely needed for the system to post. No HDD, 1 stick of ram, a known good GPU, no DVD, and only the mouse and keyboard connected. If that does not work, remove all the ram and start it. I know it won't start, but you should hear a series of beeps (which is a good thing), which will let you know the motherboard is doing what it should. Also, when you installed the CPU, did you check and make sure there were no bent pins?

If removing everything gets it to post, install 1 item at a time until you find the problem. Does that board have anything like the Asus memory OK feature. The symptoms you describe is what Asus boards do when it is searching for the correct timings and voltages for the ram to boot. It will keep trying until, hopefully, it finds a frequency and timings that will allow it to post.

Getting some ZZZZ's up building since 6:00am. I'll give these idea's a test in the AM with a clear head !
Thanks all !
