Upgraded desktop resets continuously

I know there's plenty of posts about this, but I just can't seem to find a working answer. I went through that 31 step post, but it didn't seem to help. I bought several new parts to upgrade my 5-year old system and once everything was installed, it kept resetting every time it reached the bios screen without my help. Basically, turn on, several seconds went by, cooling fans kicked up, usb mouse turns on, then a screen (gigabyte uefi dualbios) pops up and the system resets after 5 seconds..then repeat.

Currently running on 1 stick of ram, tried disconnecting all peripherals (except video since there's no onboard), reseated every connection and part and like I said went through the 31ish suggestions on the sticky post.

Here is my build:
Gigabyte 990fxa-ud3 (last part to purchase)
Atx-cb800w power supply
Amd fx-8350 4ghz vishera
Thermaltake water 3.0 (clw0223)
Corsair vengeance ddr3 4gb x4
Amd Radeon r9 280x
Samsung ssd 840 evolution 120g

I'm at a loss, please help. I really don't want to ask for a mobo exchange cause I live in okinawa and ordered it from amazon. But I will if it's the only thing left to do.

Well, alright bud, let me know if there is something further I can help with. I think we've narrowed it down pretty well at this point. Try the alternate cpu and see if you can update the BIOS. Might work, might not. Might also try some DIFFERENT memory. Some boards just don't like certain brands for some reason or sometimes just a batch of modules is not well tolerated.
All of them are fairly new except the psu which is an original part. The video card and ssd were used on the last mobo and worked fine. The rest is first time use since purchase.
 
BTW, I double checked the RAM, thinking there could be a compatibility problem, but it was of course fine, which I'm sure you already knew. Not that I know that the RAM is fine, it's just compatible. Just out of curiosity, did you try it with only one stick of RAM, with EACH stick, and, in the slot furthest away from the processor as that is the DDR3_1 slot.
 
Didn't think about it until now, the psu I just bought is 250 volt. My house is set up for 115. Qould there be any harm to my components if I used a transformer to get the 250v for this psu? I got a Seagate ss-850km. Didn't have much of a selection.
 
If it's a PSU with a switch on the back for 115/250 (110/220 US) just switch it to the lower setting. If not, you need a different PSU. You can't use a 200+V PSU with components meant to only handle 110/115. Did you already connect and power up the computer with that PSU attached? If not, don't, take it back and get the correct PSU.
 
Just finished installing and trying the new psu. Didn't work, it's still running the same. I misread the box yesterday. I was rushing because the store closed. It actually runs on power between 110 and 240 with no need to flip a switch.
 


Ok, good. Now, was it a Seagate, or did you mean Seasonic. That model number is a Seasonic part number.
 
What revision is your motherboard? Look on the box. There are about five or six different revisions of that motherboard. There are PCB revisions 1.0, 1.1, 1.2, 3.0 and 4.0. They all support different hardware and without the proper BIOS updates they don't all support the same hardware. A lot of the BIOS revisions prior to F10a do not support the 8350 cpu. Being in Okinawa you might have gotten unlucky and purchased a version of the board with an older BIOS installed.

Since you can't get the board to boot long enough to get into the BIOS and update by automatic internet update while in the BIOS (If your version supports it) or start an update from Windows, you only have about two choices if in fact you have a revision with an older bios version. (And I don't know how you're going to check that unless it stays up long enough for you to see what version you have) Return the board and get something with a newer BIOS or have Gigabyte update the BIOS and send it back to you. Or, find somebody with an older FX chip like a 4300 or 6300 or an AM3 cpu like the Phenom II and see if it will boot with that so you can update the BIOS and get the most recent version installed so it will support that cpu. It all kind of depends on the revision you have.
 
You might also double check that your revision of the board and BIOS version supports your revision and model number version of the i7 4790 as there are several different ones. I couldn't check because MSI website sucks and kept freezing up every time I tried to go to the cpu support list for MSI.
 
Yeah, I tried multiple sticks in multiple spots. I'm asking around to see if anyone has a compatible cpu I can borrow. If it still doesn't work, I'll call gigabyte to ask for an exchange.
