So, picture this: It starts with a few random black screens per day. Sometimes I could marathon games for 20 hours straight, and other times my PC would crash and restart every few minutes for no reason. Diagnosis? Pretty classic GPU crash… But the only thing I’d changed recently was turning on HDR and Windows AutoHDR, so naturally, I went down the software rabbit hole. Now, my RTX 4090 Master is already cursed. Its LCD died months ago after a Gigabyte firmware update bricked it, and no matter how many firmware or BIOS updates I try (we’re talking 50+ attempts, send help), it never comes back to life. Still, every now and then I give it another go, just in case some cosmic fluke saves me. Spoiler: nope. While waiting for Gigabyte to answer my RMA, I swapped in a backup GPU. That’s when I took out my 4090—which I know was seated right (I always double-check after that infamous connector-melting saga)—and twisted the cable a bit… only to discover that, on the side you never normally see, the cable itself was completely burnt and fried. Not just some melted plastic — straight-up cable carnage. And on the PSU side? Yikes, it was even worse: actual melted plastic, looks like someone tried roasting marshmallows inside my PC.
The wildest part? The GPU was still working reliably most of the time. It only crashed randomly, never during stress testing or when pulling a ton of power. It’s like my rig was running fine on pure spite.
I never sad any fire or problem, I have no idea when this happened.
Did Gigabyte’s legendary curse finally sabotage my system? (The dead LCD happened long before this build, so that’s separate drama.) Or am I just deeply unlucky and Montech PSUs are trash?
Send thoughts, prayers, and a new GPU & PSU😢
