GPU issues causing monitor loss of signal during specific games
GPU issues causing monitor loss of signal during specific games
Hello, welcome to the new year. I recently switched from an AMD RX 6600 XT to a MSI Gaming X Trio 4070 Ti. After restarting with DDU in safe mode and installing the latest Nvidia drivers, the new GPU performed well. I was able to play demanding titles such as GOW or RDR2 without issues. However, Helldivers 2 and GTA V caused my monitors to lose signal, something that never happened with my previous AMD setup. Helldivers 2 does this unpredictably, while GTA V only does it when I start a fresh session (???). GTA is the only game where I can reliably reproduce the issue. I've tried reinstalling drivers, re-seating the card, updating Windows, slightly lowering the clock speed, and even reinstalling the games, but nothing resolved the problem. I've also run Furmark and OCCT for long periods without fixing it. To add, my PSU lacks the 12V6x2 cable, and I'm using the GPU adapter. Any advice would be greatly appreciated. Thank you.
Maybe the signal is operating near its maximum capacity. Consider decreasing your refresh rate noticeably and see if that improves things. Investigate whether tighter frame rates can be achieved without sacrificing stability. Should that not resolve the problem, it may indicate a software or hardware-related challenge. If lowering the frame rate helps, it suggests the issue lies with the signal running close to its limits—such as electrolytic capacitors that degrade over time and cause problems even if they weren’t an issue before.
The issue is clear: it’s likely a micro spike problem under the power supply, and the PSU needs at least 700W. The MSI GeForce RTX 4070 Ti Graphics Card specification page suggests this. A Cx Corsair 650W PSU isn’t ideal for GPUs with big spikes—especially since it seems undamaged. Plus, the out-of-box adapters are of poor quality and pose a fire risk.
I have a new 850W power supply arriving, so I hope it resolves the issue. However, I wanted to ask—if the PSU trips, would my entire PC stop working? I didn’t mention that only my monitors lose signal, but the fans are still running and the lights are on. Thank you for your advice.
pc fans and motherboard may remain operational, yet a single micro spike can disrupt the GPU's signal or cut power for brief periods. the new psu model is unknown.
I hope it's of good quality since I haven't heard of that one before. It's best to ask for advice here before making a purchase.
It received numerous positive reviews on Amazon and, after exploring discussions on Reddit, I chose to purchase it.
Updated: I swapped in the new 850W PSU. GTA V no longer causes crashes on my monitors, and I'm struggling to recreate the issue. At this stage, I can only keep testing games and hoping Helldivers stabilizes. Appreciate the assistance!
Power supplies often show as unstable signals. Fascinating topic, but depending on encoding, consider a simple square wave signal (most everything is built on this or a derivative of this). It isn't a true square wave since perfect leading or trailing edge rise and fall times would imply infinite energy (yes, black hole type energy levels for a perfect square wave). Usually something called the slew rate is used to determine some character of how fast or slow the signal rises/falls. It isn't unusual for requirements to be in terms of nanoseconds on fast data, or microseconds on slow data. If the power supply sees a spike which doesn't get compensated for over those few nanoseconds, but instead over microseconds, the signal quality fails and falls outside of the slew rate. The data is corrupt, but not for hardware reasons.
People still tend to think about whether or not a given PSU is enough based on total watts, and if your clocks are slow, then this is perhaps ok. Once you get into higher performance a PSU isn't just to provide average power, it is there to provide the capability have fast rise and fall times. I like platinum rated power supplies and excess wattage, but it isn't a "status" thing. Anyone with data issues should always consider the power supply if the hardware otherwise seems to function.
