HTPC Graphics Issue

Hello,

I have been in the process of building a HTPC for the last couple of months and have run into a major problem that I need some help on.

My system is as follows

- Intel i3-3240 CPU
- ASRock B75M R2.0 Motherboard
- Sapphire Radeon 7770 Ghz Edition GPU
- Corsair Vengence 4GB DDR3 1600 Ram
- WD 1TB Black HDD
- Corsair CX430M PSU
- Cooler Master N200 Tower

- To preface, this is about the 6th computer I have assembled myself and I have never had an issue like this.

After getting all the parts together and assembling the computer for the first time, it turned out there was no display from the GPU. The fan was not even spinning, which concerned me. I instantly took the GPU out and tested in my current computer where it worked flawlessly, ruling it out. I then left it out and tried to start the computer with the onboard graphics. This also did not display anything. I reseated the CPU and that didn't fix it. The PSU was working for the case fans and CPU fan so I left it alone. All of this led me to believe the motherboard was dead on arrival. I explained the situation to some of my tech savvy friends who also had experience with building and they agreed.

I ended up RMAing the motherboard and just swapped the new one in with no success. ASRock said they tested it before sending it out, so I am currently ruling that out. The video card doesn't display anything and the fan doesn't spin. There was no display from the onboard graphics either. Now I am not sure what could be wrong. My first thought is that the GPU isn't getting power, which would explain the lack of disply and the fan not spinning, but that wouldn't effect the onboard graphics. Plus the other fans are working so the only thing I could see would be the PCI port not working. The lack of graphics from the CPU makes me think that it could be faulty, but I am not sure if that would explain the GPU fan not spinning. I am really at a loss.

If anyone has any ideas or just thoughts please let me hear them.

Thanks,
Jake

  1. There might be a fault in the 6 pin connector between your psu and gpu maybe try running the system with a different psu that one wire may be your issue?
  2. Could it also be a possibility of a doa CPU?

    If you have a spare PSU, test it with that setup to rule out the possibility of a doa PSU

    I had thought that could be an issue and it could be what is stopping the GPU, but it shouldn't have an effect on the onobard graphics right? Currently I am home on break, so I only have the CX in the computer, but I will try to see if I can grab one from a friend.

    Maybe your motherboard 4 or 8 pin motherboard connector is faulty too and the mobo isnt getting enough power.

    I think trouble shooting is the way to go here. You tested the gpu just test each part out to see if it works then you will find the faulty one. you gave your mobo in so i dont think its that either. SO im thinking either cpu or psu

    The CPU is what I am starting to look at. Which is weird, because it would be the first time I have ever even heard of one being dead on arrival. I just did a quick google search and didn't even see a thread that determined a DOA CPU.
  6. It'd be a very rare occurrence if it is the case, since Asrock stated that they tested the board and it was working properly we could rule that out for the time being

    Well, your comment about the motherboard connector just made me go back and check all my PSU connections and BAM. The CPU cable wasn't completely plugged in to the port on the motherboard. It is currently working great and installing Windows. I do remember taking the PSU out the first time and rechecking all the connections, so I think the first Motherboard may have been DOA, and then this was the reason my current one wasn't working.

    Thanks to both of you for the quick responses. I can't believe such a little thing was holding me up tonight.
  9. Hahaha glad no more RMA'ing had to be done :lol:
