Hey everyone! I'm dealing with a frustrating situation here after my rabbit chewed on my PSU cable. I have an Asus ROG Strix B550-F Gaming WiFi II motherboard, an AMD Radeon 6700XT GPU, and a Seasonic S12II-520 Bronze PSU that's been connected to a surge protector for years. When I came home, I found the rabbit had gnawed on the cable a bit, and although it didn't look too severe, the inner plastic was exposed. After that, my monitor wouldn't recognize any input. I noticed a bright white light on the VGA section of the motherboard, indicating it's not detecting the graphics card. I've reseated the GPU, swapped it with an old one, and even tried removing the CMOS battery, but no luck. The GPU fans spin up, but the monitor remains blank. Additionally, my monitor is completely unresponsive to inputs now, despite trying different HDMI ports and even testing it on other devices. I'm wondering if the chewing caused a surge that fried the PSU or something else, especially since the monitor wasn't plugged into the same outlet. Any insights would be greatly appreciated!

It's hard to say for sure, but a rabbit chewing on a cable likely wouldn’t generate a surge. It's odd that your GPU won’t start even though it requires minimal power to display. If you have an old video card, try putting it in a different x16 slot; it might help since that connects differently on the motherboard. However, be cautious about your Seasonic S12II—it’s known to have issues, so replacing it could be a good call for stability. You might want to check what else could have failed inside your monitor.
Thanks for the heads up! I didn’t know about the PSU’s reputation. I ordered a Corsair one, and I’ll try that different slot. Still hoping to get my monitor back up!
It sounds like your rabbit might have damaged the cable, but a chew on the outer layer wouldn’t normally cause a power surge. Check that cable carefully for any exposed metal. You might also want to try a different PSU power cable if you have one lying around. And have you checked the monitor’s input settings to make sure it’s set correctly to the right port? Switching to the integrated graphics on the motherboard could also help if your motherboard supports it.
I got a replacement power cord but no luck yet. I haven’t tried the display port—going to do that now. Thanks for the tips!
Definitely try the DisplayPort! Sometimes HDMI can fail without taking down the whole monitor.
Quick update: I tried the old GPU in a new slot and used a DisplayPort cable, and it actually worked! Guess it’s just the HDMI ports on the monitor that went bad.
