Monitor displays No Signal but computer boots up fine.

[Helderz]

Hi,
This has happened in the past before, but I've always managed to fix it by removing and putting back in the graphics card. Now it doesn't work.

I've also tried reinserting the RAMs, testing it out one by one, taking out the CMOS battery for a minute, holding the power button down while the PC isn't plugged, reinserting the CPU, replugging everything from the monitor, but still nothing.

I don't have a spare monitor or graphics card to test out if there's anything wrong with either of them. Is there anyway I can fix this?

I also seem to remember that this started right after I did a windows update the night before, if it makes a difference.

Your CPU has onboard graphics. Remove your GPU, connect your monitor to the MoBo and boot up.

For GPU, you have two PCIe x16 3.0 slots and one PCIe x16 2.0 slot on your MoBo. Try putting your GPU into different PCIe slot and look if it helps.

Have you checked your cable (Or tried another?) connection to the graphics card? Sometimes the case can get in the way and you moving it and reconnecting the cable could be a coincidence there making a proper connection sometimes.

The cpu does but the motherboard doesn't have video out

Didn't check the MoBo rear I/O panel connectors. My bad.

Its cool i was about to post the same thing

 

[Helderz]

Yeah, I've tried reconnecting the cables a couple of times, but nothing changes. Don't have a spare DVI cable unfortunately.

I'm assuming you mean the part circled in red? I tried that but the PCIe connector doesn't reach that far.

 

[boju]

Might be an idea to try another cable

Having no spares to try makes it hard. If the card was ok, then it could be the motherboard (bios update might help) but if can't get a picture most of the time only things we can do is suggest and guess. PSU being the problem is a long stretch of imagination and so is the mounting screws for the cpu heatsink and fan being too tight. If push pin which it looks like don't worry but if you had to use a screw driver to tension try slacking off tightness as there is a possibility being too tight could bow the motherboard area of the PCIe slot making the connection to the graphics card not straight.

I've had cases where chunky hdmi/DP cables would rest on the case chassis not going in all the way to the graphics card. Your cable might not be anywhere near the case but that suggestion was my thinking.

 

[Aeacus]

You circeled the PCI connector. PCIe x16 3.0 is one slot up. It has a fastener in it's end (visually the longest slot).

Your PCIe power connector will reach there if your rewire your power cable.
But you might need to unmout your MoBo first so that you can bring PCIe power cable directly from PSU and not behind MoBo as it's currently placed.

 

[Helderz]

Brought the video card down to the spot you wanted, but still nothing. Does this mean its a video card problem?

 

[Aeacus]

The suggestion i made was to test if your primary PCIe x16 slot is working or not.

When unmounting MoBo and then remounting it, make sure that all connectors and cables are connected. Some of them might have come loose during the relocation.

Page 2. Look for #25 to locate chassis speaker header.
That needs to be connected to hear the beeps.

Edit:
What kind of connector you use to connect your monitor to the GPU? HDMI, DVI-I, DVI-D or Display port?
You could try getting a different cable (or adapter) and connect your monitor to a different port.

 

[Helderz]

Thanks!

My monitor uses a DVI-D. Is there any other methods without using a spare cable? Don't have one currently right now unfortunately.

 

[Aeacus]

It may not have any help but try connecting your monitor to a DVI-I connector on your GPU.

Also make sure that DVI-D cable is securely connected to the monitor aswell.

 

[Helderz]

Nothing still. I guess my next step is to buy a DVI-I cable? Or should I skip that and just get a new video card. This has happened numerous times in the past so idk if the video card is starting to be more faulty since I would always just reinsert the video card to make it work again.

 

[Aeacus]

There's no point for you to buy DVI-I cable.
DVI-D uses digital signal and fits into DVI-I connector. While DVI-I uses both digital and analog signal. (Analog signal is used by old CRT monitors that can be connected to DVI-I port by using VGA -> DVI-I adapter.)

As for now, there isn't any more methods to try without spare parts.
If you had "DVI-D to HDMI" and "DVI-D to Display Port" adapters then you can check all the display ports your GPU has.
But that, in my opinion, is waste of money and without any results, you still have to replace GPU while you're left with 2 adapters that you may never use again.

The same exact thing has happened to someone else on reddit and he's blaming it on the windows 10 update. Is it possible the update messed up the motherboard or video card?

 

[Aeacus]

Anything is possible.
Searched the net and found hundreds of topics where people complained that automatic Win10 updates messed up their PCs. Mostly because the new update doesn't support the installed components.

Your GPU release date is 22 October 2010. That makes GPU almost 6 years old. Nothing to be suprised if Micro$oft doesn't make their Win10 updates compatible with old hardware.
