The graphics card ceases functioning upon power-off?
The graphics card ceases functioning upon power-off?
I received a GTX 1060 with 3GB from a friend a few months ago and installed it in my HP ProDesk 600 G1 SFF using a 430W power supply. The initial setup was somewhat unstable, but it functioned reliably at first. One day the GPU failed to appear during boot. I left the PC off for the day, tried again later, and it worked perfectly. Since then, the issue has persisted—sometimes the GPU appears on boot, other times not after a shutdown. When it does work, there are no visible problems or unusual behavior. Initially, I thought the problem might be with the HDMI-to-VGA adapter or the PCIe slot, so I set the GPU aside for months until I could test it properly. After getting a monitor with HDMI/DP and a riser cable, the card displayed on the first boot. However, the issue quickly returned. Additionally, when the GPU doesn’t show anything, neither does my integrated graphics card. Sometimes, if I wait a while, the iGPU appears once Windows loads, but most of the time it remains inactive.
The only solution I’ve tried is disconnecting the GPU and turning off the PC for most of the day, after which it usually functions again. I’m unsure what’s causing this and would appreciate any advice or suggestions.
Welcome to the forums, newcomer! I recently got a GTX 1060 3GB from a friend a few months ago and installed it in my HP ProDesk 600 G1 SFF with a 430W power supply. How old is the PSU in your prebuilt? Have you used another GPU before installing the GTX1060 3GB? Is there any BIOS version still pending an update on your prebuilt? I did a quick search and didn’t find any information about your prebuilt coming with a 430W unit or the possibility of adding an aftermarket PSU to that SFF chassis. It might be helpful to provide more details about the PSU’s make, model, and age.
Hi, thank you for your message. The search results look good; the HP ProDesk isn’t a ready-made unit but resembles an office PC similar to the OptiPlex. I also received a PSU from a friend. It’s a Thermaltake Smart 430W, which is around one to two years old. It was in decent shape when I got it. I’ve been using an adapter to link the PSU to the proprietary motherboard. This is my first GPU, and I haven’t used any other GPUs in the ProDesk besides the built-in iGPU. There’s also a BIOS update from 2020.
I managed to get a display last night by shutting down my PC, unplugging the PSU, and discharging the system. I also removed the CMOS battery and reinserted the riser. It booted up, but only showed 'Basic Display Adapter' instead of the GPU name. In Event Viewer, I noticed that some NVIDIA-specific drivers weren’t installed. After exiting the BIOS, the GPU stopped displaying anything. I’m wondering if this could be an initialization issue or if my PCIe slot is faulty.
There are a few things to think about, such as the CPU possibly needing to be repositioned again. The RAM might also require reseating. You can use the beep codes to help identify the problem, provided the buzzer speaker is functioning correctly.
I purchased a similar PC about seven years ago, refurbished, for family use. When I received it, I had to reinsert the CPU to stop it from looping during boot. It took me two attempts to fix it each time it shifted or was disturbed.
It seems the issue could relate to the CPU socket or pressure on the heatsink in a cold environment, which might prevent the pins from making proper contact with the CPU pads.
Another factor to consider is whether the replacement power adapter is fully connected or if it’s faulty. This model might be linked to the link: https://www.moddiy.com/products/535...n-...eDesk.html
I don’t receive any beep codes with this problem. My PC starts up with a black screen when the GPU is installed. I followed your advice and re-seated my CPU and RAM, but then it actually showed something. When I turned off and back on the PC to check, there was no display again. I can’t confirm if the adapter is damaged, so I tried using an aftermarket PSU as an external power source just for the GPU. Still, no output came through. The only unusual thing was that the CPU fan was much louder than normal. I’m not sure if this might be the cause. At this stage, I’m just trying to figure out which part could be faulty so I can replace it.
Is this part of your replay with the iGPU, or are you attempting the 1060 3GB once more? The louder than usual CPU fan suggests the system might be locked up or frozen (a typical issue linked to CPU pins), overheating, or both. Make sure to reapply paste if the CPU functions normally and the display appears. Unless there’s a fault in the PCIe slot, GPU, adapter, or PSU, it’s possible a bent or damaged CPU pin, broken pin, or faulty PSU is causing the problem. If feasible, switch to another PSU connected to your PC and test the 1060 on a working machine to confirm functionality.
