[Solved] The computer won't turn on after inserting the graphics card

Durmond 25566 16
Best answers

Why does a computer not start at all when a GTX 1050 Ti graphics card is inserted, even though it starts normally without the card?

The graphics card is likely shorting the system when it is inserted, possibly because the cooler touched and damaged a track on the card [#18692378][#18692436] Test the card in another computer to see whether it powers up there [#18692444] If it also fails in the other PC, the card is probably faulty and should go for replacement/warranty [#18692436] If it works elsewhere, then check the motherboard PCIe slot or your PSU, because a damaged slot or a power supply protection shutdown can also prevent startup [#18692449][#18692444]

    Hello
    As in the subject, a computer without a card normally starts after inserting it, I don't want to, even when I reset the bios
    Graphics card: gtx1050ti
    Processor: i7 3770
    Motherboard: MSI h61m-p31(G3)
    PSU: XFX 400w Core XT
    I checked on calculators and the power supply should pull it without any problems

    Nom to integrated because after connecting the graphics card, the computer does not start at all.
    Could it be that the card is making a short circuit?

    Well, it doesn't want to run. Yesterday I mounted kuler and everything worked fine after about 30 minutes the computer turned off and did not want to start only after removing the graphics card it fired

    You're so talkative you don't even know what you're talking about. So when you connect the monitor to the integrated card, do you have an image on the monitor or not?

    Yes, when connected to the integrated card, everything is normally displayed and works.

    And in the BIOS you change which card you prefer?

    After a reset, the BIOS sets the integrated card as the default.

    I see that my colleagues have problems with reading comprehension.
    The OP writes that the computer does NOT boot at all, not that it boots BUT there is no image.

    @Durmond Have you had it since new or did you buy it used? I think that's the problem with her. It's probably causing a short circuit and won't start. To be checked on another computer. If it starts on another, you need to look at your power supply because even though it has enough power, it may be damaged and not be able to power it.

    Are the power cables to the graphics card connected properly? Does it sit well in the PCI? What slot are you plugging the monitor into?
    And most importantly - what does it mean that it does not start? CD starts?? are the windmills spinning? Maybe the wrong image source is selected on the monitor?

    Well ok, because I even disconnected the fans and everything to reduce the power, and so when connecting the card, it does not turn on every time. The problem occurred yesterday, after installing a new kuler, the computer runs for 30 minutes and went out. I don't know, maybe it's because I have a small motherboard and this kuler was in contact with the graphics card?

    Well, we may have an answer. It was enough that the aluminum part of the cooler touched the track on the graphics card and it burned. That's where I'd start. So check the card in another PC. If there is also no question -> warranty card if it has, if not then ... there is a problem.

    It sits so well, what's strange is that when the card is connected to the power supply, the computer starts, everything spins, but as soon as it is connected to the PCI, the computer does not start at all, without the card it starts normally and displays the image on the monitor.

    Any contact with the card could damage it. You need to test the card in another computer to determine if the card is faulty or the motherboard.

    As I say -> if the power supply has short-circuit protection, then when the paths on the graphics card are shorted, which could have happened, the power supply will not move with the card in the slot. At least that's how it should work from the power supply side. Now the question is what happened to the card. And you can't check it if you don't transfer it to another computer. Because it is possible that the card survived but somehow damaged is, for example, the PCIE slot on the motherboard ...

    Problem solved, in fact, the graphics card in contact with the kuler must have been damaged so it is suitable for replacement

FAQ

TL;DR: 75 W from a PCIe x16 slot; "up to 75 W". If your PC won’t power on after adding a GPU, suspect a short or PSU protection; test the card in another PC and check cooler clearance/BIOS primary display. [PCI Express Card Electromechanical Specification]

Why it matters: This helps DIY PC builders quickly isolate no‑power faults after a GPU install without unnecessary part swaps.

Quick Facts

Why does my PC refuse to power on after inserting a graphics card?

This behavior points to a short on the GPU or PCIe slot, triggering PSU short‑circuit protection. In that mode, the PSU can shut down instantly and fans may not twitch. Test the GPU in another system and inspect the slot. As one expert put it, "the power supply will not move with the card in the slot." [Elektroda, icey33, post #18692449]

How can I confirm if the graphics card itself is shorted?

Move the card to a known‑good PC and see if it powers on. Inspect the card for scuffs or burn marks near traces and mounting edges. Look for any area that may have contacted a metal cooler. As reported, "the aluminum part of the cooler touched the track on the graphics card and it burned." [Elektroda, icey33, post #18692436]

My PC works on the integrated GPU but won’t start with the dGPU installed. What does that indicate?

Integrated graphics working confirms the CPU, RAM, and PSU can boot. Failing to power on with the discrete GPU seated indicates a fault with the GPU or the PCIe slot. Remove the card and the system should boot normally, as observed in the thread. [Elektroda, Durmond, post #18692442]

Do I need to move the monitor cable when I add a graphics card?

Yes. Connect the monitor to the ports on the installed graphics card. If you leave the cable on the motherboard video output, you may see no image even if the system boots. Switch to the GPU’s HDMI/DP/DVI outputs for display. [Elektroda, mariuszp19, post #18692224]

Which BIOS setting should I check after clearing CMOS?

After a reset, many boards select the integrated GPU as the default display. Change Primary Display/Init Display First to PEG/PCI‑E in BIOS. As a reminder, "After a reset, the BIOS sets the integrated card as the default." Save and reboot. [Elektroda, mariuszp19, post #18692307]

Can a CPU cooler touching the GPU really kill the card?

Yes. Physical contact can bridge traces and cause a short, damaging the board. This thread’s failure followed cooler contact near the GPU. Quote: "the aluminum part of the cooler touched the track on the graphics card and it burned." Ensure clearance and add insulation if needed. [Elektroda, icey33, post #18692436]

How much power can a PCIe x16 slot supply to a graphics card?

A PCIe x16 slot supplies up to 75 W to a card. Higher‑power cards use 6‑pin or 8‑pin connectors for additional power. This matters when sizing PSUs and diagnosing no‑power faults after GPU installs. [PCI Express Card Electromechanical Specification]

Could the motherboard’s PCIe slot be the problem, not the GPU?

Yes. A damaged slot can short or fail to initialize. Cross‑test: try the suspect GPU in another PC, and a known‑good GPU in your board. "You need to test the card in another computer." This isolates the faulty component quickly. [Elektroda, krzychupar, post #18692444]

Fans spin only when the GPU is powered but not seated—what does that suggest?

If the system powers with the GPU powered but not in the slot, yet won’t start when fully seated, the PCIe interface path is shorting. That points to a bad card or damaged slot, not an overloaded PSU. [Elektroda, Durmond, post #18692442]

What was the final fix in this case?

The graphics card was damaged by cooler contact and had to be replaced. After replacement, the system powered on normally. This confirms the GPU was the fault, not the PSU or motherboard. [Elektroda, Durmond, post #18695675]

How do I avoid shorts when installing a large CPU cooler near a GPU?

Check for mechanical clearance around the PCIe slot before tightening. Keep metal fins or brackets from touching the GPU. Add insulating spacers or edge guards if tolerances are tight. This thread shows direct metal contact burned a trace. [Elektroda, icey33, post #18692436]

How do I troubleshoot a no‑power PC after installing a GPU? (3‑step checklist)

  1. Test the GPU in a known‑good PC to see if it powers on.
  2. Test a known‑good GPU in your PC’s PCIe slot.
  3. Inspect for physical contact, bent slot pins, or scorch marks before re‑seating. [Elektroda, krzychupar, post #18692444]
