New GPU, no display attached, only integrated graphics available
New GPU, no display attached, only integrated graphics available
Good evening everyone, it's been over three months since I purchased the used EVGA GTX 1660 Super SC Ultra for my university programming and Minecraft sessions. I'm looking for more than 60 FPS, but the issue remains—I can't get a proper image. I noticed that when the cable is connected to the GPU, the screen shows "no signal," yet the monitor still detects it. Even when the screen is blank and iGpu is turned off in the BIOS, I still hear Windows 11 sounds through my headphones.
I tried several fixes: I checked the graphics card on a friend's PC and confirmed it worked. I adjusted BIOS settings, cleared CMOS, and bought a new motherboard and CPU after suspecting hardware issues. I also purchased a new 650W power supply from BeQuiet and watched repair videos on YouTube, hoping someone else had similar problems.
However, the symptoms persisted after swapping parts like the RAM contact pins (which I plan to clean tomorrow). My current setup includes an i3 8100, Gigabyte B360M H, 2x8GB DDR4, and a Corsair CX450. The GPU is still the EVGA GTX 1660 Super SC Ultra, and it doesn't show up in Device Manager even with the new components.
What can I do next?
I likely would have tested a different GPU before thinking the board or CPU was faulty.
The GPU is definitely functioning after I used it on my friend's PC.
The 1660 could require UEFI startup if Windows was set to legacy mode, which might be the cause. I've also encountered problems with older hardware where the BIOS only shows up on certain video port connections, like HDMI instead of DisplayPort. This could be linked to UEFI behavior from previous BIOS versions that handled it differently. If Windows is installed in UEFI mode, it should function properly.
This confirms the GPU is functioning on their board, not yours. Many components have undocumented or unresolved compatibility issues. These are typically fixed via updates, but if few users face this problem with certain hardware from specific OEMs, the issue might remain unknown. A possible solution is to switch to a different GPU on the board, which I would have considered before proceeding.
Consider adjusting your BIOS settings to UEFI only and reinstalling Windows. To preserve your installation, perform a MBR to GPT conversion beforehand (search for instructions on switching to UEFI BIOS). It might be worth starting fresh if you've explored many solutions, and ensure your motherboard's BIOS is up to date.
That’s a good idea. Just take the SSD out while Windows is running and check for a BIOS/UEFI image.
