Alright here is a list of my internals
1 MSI FM2-A75MA-E35 Motherboard
1 Gigabyte Radeon R9 270X
1 Corsair Vengeance 8GB ram
1 ASUS Optical Drive
1 WD 1TB harddrive
And 1 Corsair cx 500W power supply

My Question for you guys is this: do i have a big enough power supply? All my Parts are compatible with each other yet i still have no video i just want to make sure i have enough power before i go replacing parts. TY in advance for your help.

Hello there.

On some graphics cards they required additional power rather than just going off the main board. Have you checked the instructions on your graphics card?

Also, does your PC boot up without the graphics card installed?

You need to check how many watts each component requires.

i'd suspect you may need a higher wattage power supply.

try disconnecting hard drive, CD ROM and other things leaving CPU memory in and see if you get any output on the onboard VGA.

On my GPU i have 2 6 pin connectors where the PCI-E goes into. After adding all the watt usage up(not including fans) i got roughly 375 W after cross checking a few places. Gigabyte recommends 500 W power supply to have enough for your other parts. I had also tried booting without the GPU And extras disconnected and got nothing. Also i tried it with just the GPU in just in case but still nothing.

is this a new build?

Does your motherboard have VGA output?

You're telling me you get no display even with just memory and CPU on your motherboard?

Not even any POST beeps?

Yea I'm working on a new build since my old one couldn't handle an upgrade on parts. My mobo has both VGA and HDMI outputs both gave me nothing. Running a skeleton system didnt work and the msi motherboard i have only beeps when no ram is inserted or detected. It's a bit of a conundrum isn't it.

Really, if you're not getting any display when using basic components you need to start looking at CPU and RAM first then motherboard.

Pull EVERYTHING! Try to get it to beep! Just suggestion, at least you would be starting with an indication. Put in cpu only no ram, if no beeps still, look at mobo.

The only beep I get from the mobo(the only beep it gives) is for no ram/mem.

Tried that too. The only thing left was the power and a malfunctioning part.

What is your CPU type? You never mentioned.

After looking at RAM specs:

1 Corsair Vengeance 8GB ram
DDR3 PC3-24000 (3000MHz)

1 MSI FM2-A75MA-E35 Motherboard
DDR3 1066/1333/1600/1866/2133*(OC)

do you have another mobo or ram to try with the other?

My CPU is an amd Athlon x4 (can't believe I forgot to add it) and unfortunately my old mobo is just that. It's too old and none of the connectors line up right. The ram is in the same boat.

did the ram and mobo ever play well together?

It's a new build so sadly I can't say but after checking online they are compatible so they should be able to work well together.

Before you removed any thing from static bag, did you walk around the house with wool socks on, dragging your feet? I hope not. I also hope that you are using a ground strap, or at least grounded yourself before touching anything. If you cannot verify either one as good, you would have to assume the ram is bad, like the beeps are telling you. Wow, Hang in there. No bios output on the video at all. Is this a known good monitor, and does it(PC) run just no video output?

Can you also look at the motherboard manual to check you've got the correct memory. Even though the modules may fit, they might not be the correct speed.

I don't know much about the current batch of AMD CPU's are they as big a power hog as the older generation? If you have a six or 8 core monster it might need a 600W power supply. But, without the video card the MB should function fine on 500 Watts.

It appears you did some if not all of the standard diagnostic steps - like disconnecting everything and reconnecting the parts one at a time.

So at this point you have a problem with one of the following:
1. power supply
2. motherboard
3. CPU
4. case

The first thing I would check is all the power connections and eliminate any possible shorts between the MB and the case. Is it possible to remove the MB from the case and try to boot the PC that way?

The second step would be to use another power supply. I have had at least one working PS that would not boot my new motherboard but never had a problem with any other MB.

The final step is to see if you can return the motherboard and CPU. There is just not much you can do to diagnose them and it's best to start over with a new set. I hope you bought them from the same supplier.

Good Luck

I want to say thank you to every one of the suggestions you guys made. Somewhere along the line something must have clicked into place because after a few days of sitting without the power supply plugged in I decided to give it a boot before i did anything and she runs now. You guys were a great help and keep up the work.
