No video from RTX3080
No video from RTX3080
So this situation is a bit unusual—I purchased a used PC online, but upon delivery, there was no video output. Instead, there was a prolonged series of beeps, indicating the GPU had been dislodged. I promptly opened the case and reinserted it, which resolved the sound issue, though video remained absent. I believe the GPU may have shifted and disturbed the PCIE connector during transit, as it functioned properly when tested at the original purchase location. However, the transport likely caused damage, leaving both the connector and the GPU misaligned.
Additionally, there are some odd observations that aren’t clear.
My troubleshooting steps included:
- Connecting two different HDMI cables to separate displays
- Using a brand new display port cable with a new monitor
- Testing on all ports, including the built-in DP and HDMI, as well as the 3x DP/HDMI on the GTX1650
- Running the GTX1650 from my old machine inside the new PC, which performed poorly and eventually stopped powering on until I changed the power cable
- Removing the GTX1650 to check if it would boot with the built-in graphics, but it still didn’t work
- Trying to install the GPU in the old system due to space and power limitations
- Removing the 3080 to see if it would use the onboard graphics, which also failed
- Resetting CMOS by removing the battery, shorting a jumper, and then connecting the power terminals for a minute
Despite these efforts, the PC still won’t boot or utilize the GPU after removal.
I also attempted to fit the GPU into the PCIE slot, but it was too tight, and I heard intermittent noises—possibly fans—though no video appeared.
It seems there might be an issue with the motherboard or CMOS, and possibly the main board itself. The CPU is an i9 11th generation, and the motherboard is an Asus x590-p Prime.
You possess the physical custody of the PC, correct? If yes, open the PC and capture images of its internal components. You may upload these photos to www.imgur.com.
MoBo Rev1.1 appears to be from Gigabyte. Asus does not release revisions for this model.
The PSU label might not appear until you remove the power supply unit. I recommend doing so and sharing the label image here.
You mentioned an RTX 3080, but which specific one? There are 210 different variants available.
Here is a detailed list:

The RAM model is listed on the label. Simply remove a stick and check what it says. The same applies to SSD, HDD, or M.2 drives.
If your CPU is an i9-11900KF, then it lacks an integrated GPU. (The 'i' in i9 refers to integrated graphics.) This means the build would require a separate dedicated GPU.
You can identify the CPU by removing the cooler and cleaning the thermal paste from the IHS. The printed text on the CPU will reveal its exact model.
Without precise details about your hardware, diagnosing the problem becomes extremely difficult.
Analogy: Imagine entering a car repair shop and stating your vehicle has an issue, but the mechanic only knows it has four wheels, is red, has four doors, and a front engine. The best advice would be to check if you've added fuel or diesel—this gives a very general solution.
Based on the information you provided, I suggest testing with a second, reliable PSU. Since the internal PSU isn't confirmed, it could be a low-quality Chinese component. It might be safe to use a known good PSU instead.
Ahhh! The CPU lacking built-in graphics clarifies what I observed in that situation. Now that we understand this, it’s safe to say the issue is likely due to a faulty motherboard.
It’s nearly impossible to proceed further without adding extra components, but I’m relieved this resolves the confusion.
