Hey everyone, I'm looking for some help or insights regarding recent issues I've been having with my gaming setup. My PC tends to freeze randomly, resulting in both monitors going black while the fans ramp up to full speed. This can happen within the first 20 minutes of gaming, regardless of whether I'm just on the home screen or in-game. I used to notice that opening a web browser would trigger this issue almost immediately, but now it seems to occur spontaneously, even with no programs running.
Here's my setup:
- Acer Nitro 60 Gaming Desktop
- Intel Core i7-14700F
- 32GB DDR5 Memory
- NVIDIA GeForce RTX 5070 Ti
- 2TB SSD
- 850 watt power supply
For my monitors, I'm using an LG 4k Ultra Gear OLED as my primary (connected via HDMI) and an LG 4k Ultrafine as my secondary (connected via DisplayPort). I've already tried various troubleshooting steps from previous discussions, like switching my PCIe settings and checking my power supply and connections. I've also reinstalled the NVIDIA drivers completely. I'm really at my wit's end and would love any advice on what I can do to resolve this. Thanks for your time!

This sounds less like a monitor issue and more like it could be related to your GPU or power supply. The fact that both screens go black and the fans max out suggests a potential GPU crash or PSU instability. Here's what you could try:
1. **Use DDU to uninstall NVIDIA drivers**: Do this in Safe Mode, then install a slightly older, stable version.
2. **Lower the GPU power limit**: You can do this through MSI Afterburner, setting it at around 90%. If that helps, it might indicate issues with your PSU under transient loads.
3. **Monitor temperatures**: Use HWInfo to check the GPU's hotspot and VRAM temperatures, not just the core temp.
4. **Test with one monitor**: Sometimes dual 4K setups can reveal instability that one monitor might not show.
It might also be worth checking the exact model of your PSU—850W should generally be fine, but quality matters a lot! The max fan speed often points to protection mechanisms in your GPU kicking in due to a crash.
This is ridiculously helpful! I’ll definitely try these steps one by one tonight. I also believe this might be a GPU issue. I’ve kept an eye on the temps and fan speeds using the Nvidia overlay, and nothing has jumped out at me yet. Peak temp is around 71°C, which seems normal. I’ll report back once I’ve tested everything out. Thanks a ton!
