Motherboard Problem?

[EnderColt]

So I recently put in a new graphics card for my recently built computer and at first it worked but after a couple of minutes it stopped working and when i would try to turn it out it made 1 long beep and two short beeps.

 I found out this meant a video error so i tried using three different video cards, I tried a different monitor and different connectors. I also tried resetting the cmos and that didn't help at all either. I also tried the other psi port on the motherboard and that didn't help either.

I'm thinking that it may be a motherboard problem and that ill have to buy a new motherboard but I'd like to know if there's something else I didn't think of that might fix it before doing that.

My Motherboard is a MSI gaming 970  http://www.newegg.com/Product/Product.aspx?Item=N82E16813130790
My graphics card is a Rx 470 (I also used the gtx 650 and Radeon 8700 I think, which both were working just fine with the same setup before)

Assuming the 12V connectors have been properly plugged into the molex for the video cards, I would try swapping out the power supply first before blaming the motherboard as for a weak power supply could cause the video card to fail to operate properly. Be sure the power supply is rated for a gaming video card of 500 watts or higher.

i know what i will say maybe stupid but just try

get small screwdriver not (+) use the (-)  and put into the vga place in board " make sure everything is off, mean no power at all " and move it softly to make sure all pins in there places

then try to use a cleaner spry and wait till totally dry
then try put ur vga card again and make sure the 12v cable plunged in and all cables are correctly connected

Please ignore the above advice...

Yeah, DO NOT DO THIS unless you want to destroy your motherboard.

My psu I bought is 600W and everything seems to be powering on just fine. This is the power supply I bought http://www.newegg.com/Product/Product.aspx?Item=N82E16817182331
Also I went ahead and checked the 12V connector and it started working and then I moved it because part of the chord was in the way of the case and thats when it stopped working. I'm thinking that buying a new 12V cable would fix the problem?

That PSU is Modular...it should include more than 1 12V cable...

Yeah unfortunately this PSU is weird and it has all the 12V cables attached through one chord. One cord plugs into the PSU and then it splits off into two 12V cables close to the end of the cable

If just moving the cord caused it not to work i'd return it immediately for a replacement...

Do you know a way to just buy a PCI power cable? If not I'll probably end up returning it.

Return it...before it's too late...

So I rechecked the cable connecting it to the power supply and my computer works fine now. It must have gotten loose or something when i was moving some wires around to put on the case panels.

Good news...
