Recently, I bought a newegg DIY tower kit. After putting it together, I found that everything seemed to run, purr and light up except the monitor. I cannot get it to display on any monitor via VGA or HDMI.

 

I emailed my dad for advice and tried taking out the graphics card as well as trying with just the CPU, fans, main power plugs and power switch, with no luck.

 

I'm stumped. Please advise if you can.

Ok, in bios, is video set to "onboard" or "addon/addin card"?

What's your motherboard model number and brand. Also what model number is your graphics/video card and what brand is it?

I would not know.

Like I said, the computer will not show up on the monitor in the first place.

 

 

 

The motherboard is an ASRock Z75 Pro 3 and the video card is a msi R7770 PMDIGD5 GHz Edition.

Does the motherboard have an onboard VGA port?

Yes, that is what I have been trying to use, though I have used it's on-board HDMI, as well as the HDMI of the video card.

Ok, take the add in card out, then pop the CMOS battery out to reset bios settings, wait like a min, then connect the monitor to the on board VGA on the motherboard, pop the CMOS battery back in, plug it in and start it up. The bios should default to the on board, one note: keep the add in graphics card out until we set the settings correctly.

I also tried clearing the CMOS with the pins as I tried yesterday as an idea my dad had.

 

Unfortunately, no dice. I still have nothing on-screen.

Well, it's back to basics time.  Some of the stuff I mention might be insulting, not meant to be.

 

Power connectors-  Both the 24 PIN and the 8 PIN are connected?  Nothing wrong with pulling the power plugs and verifying there are no pin pushouts.

Memory- Tried booting with one stick, swapped slots?  What memory?  1.5 or 1.65V?

 

CPU-  All the socket contacts happy?  Anything bent?  What CPU?  What BIOS revision (should be on the box somewhere).

Excuse me for saying this, but, is the monitor plugged in and or turned on?

heh, yes, the monitor is plugged in and on. I've even tried a second monitor.

The kit came with one set of RAM. A DDR3 8GB Corsair XMS3. I have tried with, without and even in different slots. Not sure on the voltage. Surprisingly, it does not say on the box or small warranty paper.

 

Edit: I double checked the CPU and power connections. Still nothing.

So, you say it boots up correctly, you hear the HD spin up and the fans kick on etc? Is the graphics card seated properly in its slot?

If all the power connectors are properly seated, I would suspect that the PSU is defective. I replace a lot of PSUs that will spin up the drives and fans, but won't boot the system, usually due to low voltage to the 12v connector to the MOBO. Any DIY computer tech needs a power supply tester, with an LCD read out. No matter what PSU you have, you sometimes get a lemon. If you can beg, borrow, or steal another PSU for testing purposes, I'd try it.
