I am currently helping my little brother putting a new system together because his old motherboard died. We only replaced the Motherboard and CPU since he didn’t have a GPU and he wants to get one later this year for cristmas. We reused his old HDD and PSU.
CPU AMD A-Series A10-5800K (has integrated GPU)
Mobo Asrock FM2A88X EXTREME4+
RAM 2x Kingston 99u5471 4gb or 1x Elixir M2F8G64CB8HB5N-DI 8gb
PSU ATX-450W P4 (I don't know the exact vendor or Model, this is whats printed to the side of it. It came with his old Amazon PC.)
HDD Seagate ST 1000DM003
After i put his system together everything started up nicely (CPU fan and hard drive both spin up). However the monitor which is connected via VGA gives me a "No signal" warning. I also tried hooking it up to our TV with a HDMI cable but it also doesn't show anything which is why I am sure it's a problem with my build.
Things I tried
- I tried breadboarding it. I checked every connector with a minimal
setup, with and without HDD and only my spare boot button. It still
seems to start up but I don't get video.

- I also tried booting with just a single RAM stick in every possible
RAM slot but still nothing.
- I removed the battery on it and put it back in. (I don't know what i expected)
- I connected an optical drive and tried booting with the CD that came with his motherboard
- I tried to put his old A6-5600 processor in there. Still nothing.
I am not completely inexperienced with building PC's but there must be a stupid error i am not spotting. Otherwise I don't know what’s the cause for my problem. Could it be a UEFI/Bios error or something? The odd thing is that his old computer died the same way after he changed the GPU. The old one also had a FM2 processor with integrated graphics. I honestly don't know what to do anymore and my brother is getting frustrated because ha can't play his games. Do you guys see anything wrong with my work?
I do believe you need to plug in both ports of the CPU power connector OR switch the plug set. There are 8 pins there, therefor you need to be able to power all 8 pins.
Also you don't have any ram in.
Hi Lukas, I am myself not an experienced PC builder but I'll tell you the same advice as I was told: Remove everything and start over. Make sure you follow every steps correclty and if you're not 100% sure, just go read the manuals. I, for myself plugged my ram in the wrong slots.
Instead of 1 (2) 3 (4), I plugged my ram as (1) (2) 3 4.
You can follow step by step on how to build a PC on youtube as well.
I tried every one of my RAM sticks in every slot. Sorry if that wasn’t clear.
Try using the DVI, Sometimes VGA and hdmi can be buggy without drivers and a firmware update.
I tried it with every one of my RAM sticks, i just didn’t put them in when I took the photographs.
Will try that when I find a monitor with DVI. Thanks.
Do you have another PSU? Pretty sure 4 pin only handles up to 95W (edit actually I think it's a lot less) and that's a 100W CPU...
Also you might want to make sure that 24 pin is plugged all the way in. It looks like there is a gap and that could cause a issue.
Damn that could be the problem. I will buy a new PSU or I will ask my friends for an old one. Thanks dude.
It’s fully plugged in I just put it together for the pictures. Thanks anyway.
there two different 5800k's , one of which is not listed as a supported cpu on the motherboards list.
The only difference between the cpu's is the part number. one come with a heatsink , the other doesn't. The board doesn't list the AD580KWOHJBOX as compatible , but only the AD580KWOA44HJ.
This SHOULDN'T matter , but could technically be possible that the board and cpu aren't compatible simply due to a part number.
Couldn't see in your Imgur album, but a commonly overlooked "no video" problem is the European/American power switch on the PSU. If yours has one, make sure it's set to your local voltage setting.
That cheap thing doesn’t have a switch at all :) Thanks anyway.
Also the board gets a lot of bad ratings on newegg for a lot of various problems so it possible it can be a doa.
OK thanks I hope this won’t turn out to be the problem.
I was just about to say the same thing. I was going to suggest that OP has gone through reasonable steps to get the hardware working and should consider RMA.
Thanks to all of you guys. I will try everything once I get a dvi monitor and a new PSU. I will report tomorrow.
