My capture card is driving me crazy

[JomSpoons]

I have an Elgato HD60 X that, when used with my Windows 11 laptop, works flawlessly. However, when I use it on my Windows 11 desktop PC s*** hits the fan and I have absolutely no clue why. There is a constantly recurring issue where the capture card will freeze after a short time, ranging anywhere from a few minutes to a few seconds. Every time this happens I have to remove the device from the sources list and re-add it, usually also needing to Activate and Deactivate it in the process. There is no indication as to why this happens and the OBS logs don't contain anything regarding the freezing. This issue isn't exclusive to OBS either, it also occurs in the Elgato 4K Capture Utility. I have seen others on this forum with similar issues on their own Elgato capture cards but none of the solutions those threads provided have helped in the slightest, nor has anything I've come up with myself.

Here is an extensive list of everything I've tried:

• Performing Windows driver updates
• Performing Windows integrity checks (sfc /scannow and DISM)
• Performing a driver update from the device manager properties
• Removing the card from the device manager and scanning for hardware changes
• Disabling any and all USB port sleep / power saving functions I could find
• Updating OBS (and 4K Capture Utility)
• Verifying the integrity of OBS
• Doing a clean install of Windows 11 and immediately trying to use the card in OBS
• Installing Windows 11 and OBS to another drive
• Updating my motherboard's BIOS
• Using different USB ports
• Leaving the USB port adjacent to the card's empty to reduce power draw
• Swapping out my motherboard and power supply with new ones
• Using different USB cables (including a USB-C to USB-C that works great with my laptop)
• Using different HDMI cables
• Using a separately powered USB hub to connect the card (read somewhere that this can help sometimes)
• Getting a new power strip (surge protected, if that matters)
• Plugging my PC directly into the wall
• Getting the card replaced (Previously I had a HD60 S+, Elgato customer support sent me the HD60 X in return. Both have this issue.)

I feel like I've exhausted every option at this point so if there is anything I'm missing PLEASE let me know. I am at a total loss and I have no clue what is going on. Thank you.

I have a similar issue except it doesn't freeze. It just starts stuttering in the preview. I had the elgato HD60 X. (Preview stutter without even recording. No lost frames in the stats.)

Returned it and got a Avermedia GC 573 instead. It's an internal capture card. Guess what... SAME ISSUE! I'm losing my mind.

What's even more baffling is that. In the Avermedia software. There's no issues, completely smooth. So I came up with the brilliant idea of fullscreening the preview from this software and then screen capturing on OBS... except, SOMEHOW it still stutters on OBS.

Smooth in the avermedia software/stutters on OBS. How is this possible? I need some expect to explain what's happening!

I've tried everything you've stated. I can't figure it out.
