Yesterday I received all my computer parts and I put them all together. Everything is connected correctly (at least that's what I think). The problem is, when I turn on the computer, I'm not getting any display and the bios won't load. Completely NOTHING appears on the monitor, it's just a black screen.

All the devices which are connected to the motherboard are working fine (HDD, SSD, CD/DVD Reader). All the fans are working, all the LED lights are working too. I'm just not getting any display.

Things I tried (none of them worked):
- Removing the GPU and connect a VGA cable to the integrated video-card of the mobo.
- Removing all the 'extra' devices: SSD, HDD, CD/DVD Reader, wireless internet receiver.
- Removing the RAM Sticks in order to find out whether the mobo is indeed working. When I removed them, I got 3 beeps right after I turned it on.
- Running a Start-Up CD which was given with the mobo package. Also tried Linux and Windows, of course nothing works.

I thought I could conclude of all this that the motherboard is NOT DOA, but in other threads which I have checked, they said this may be the case.

List of hardware:
- CPU: AMD A10-6800K
- MB: MSI FM2-A75MA E35 (µATX)
- PSU: Corsair CX600W
- HDD: Western Digital 2TB
- SSD: Samsung 128GB
- GPU: ASUS AMD Radeon HD7770

TL;DR
The BIOS won't load and I'm not getting any beep nor display. Fans + lights work. I have absolutely no idea what could solve the problem, I'd be amazed if anyone could find a (working) solution for me.

Thanks in advance

Did you plug in the CPU power pins ? Your problem directly towards me to there, according to your description. Sometimes we all forget small things :)

I have an 8-Pin CPU power cable coming out of the PSU. On my motherboard, there's a 4-Pin plug-in, means I can't connect them all.
When this wasn't connected, I could only turn on the computer, but couldn't turn it off. I had to take off the electricity to turn it off. When I connected this cable, I could turn it off with the power button, that's all which changed.

But yes it is connected, only 4/8 pins

I assume you have somethings going wrong with cpu power, since it doesnt post. Are you sure you are connecting the correct cables ? If all the cables are correct then maybe the mobo is defective or the psu or the cpu.... Whoa lol sometimes its a mess :)

It would be very hard to believe that the PSU is defective. The power on the motherboard is 100% working and the CPU-Fan is running as well and the CPU is connected correctly. If I can believe the instructions which were delivered with the mobo, everything is connected correctly. I hope nothing is actually defect...

I had a very similar problem which i only figured out through extensive googleing.

It was a new build for my girlfriend at the time - ivy bridge i5's had only just come out. I put everything in, double checked all connections but i was getting the exact same problem - would boot, all lights on, all fans spinning, however nothign would display. I tried taking the GPU out and plugging directly into the onboard graphics but still nothing.

With the asrock MB's it has a dr debugger on it. which would display certain letters displaying certain errors.

I found that the bios was out of date for ivy bridge (even though it stated it was supported). I didn't have an older chip so had to take it to the shop to flash the bios to the correct version. After that, it started fine.

Have you got any older chips that would fit? If not, perhaps take it the shop and see if they can update your bios - only cost me £15 at the time so not a expensive thing to do.

I'm contacting the store where I bought the items via e-mail. I will be waiting for a response.

By the way, what do you mean with a chip? A Processor?
This motherboard has a FM2 socket, it's particularly made for the processor that I have now.

An older CPU chip that fits into the same board. Sometimes through a fault of the manufactor the MB will come with an old bios that won't be able to read the newer chips. What they would do when flashing the bios is put an older one in, update and then put the newer one in.

Let us know back here what the store says.

The store told me I could return the pc parts which may be defect or the whole computer and they would check if everything is alright. They said they could update the motherboard as well. In both cases I must fill in a RMA report.

For me, my problem was the same. A homebuilt. I followed a youtube video to diagnose my problem. It didnt beep, but fans. etc.

My cmos had to be reset, and I found my ram module had to be reseated in a different slot.

sometimes, from what I read, it can be factory set with old bios information for other cpu or settings.

I had to reset that cmos with the jumper and took battery out. it turned on and beeped no ram.

I put ram in a different slot, and it posted.

hope it helps.
