I'm having some trouble with my son's PC. It shuts down completely—screen goes black—when he's doing heavy tasks like video editing or rendering. Here's the setup we've got:
- Windows 11 Home
- Intel Core i9 14900KF (3.2 GHz base, up to 5.6 GHz with Turbo Boost), with 8 P-Cores, 16 E-Cores, and 32 Threads
- Graphics Card: Gigabyte GeForce RTX 4070, featuring DLSS 3.5 AI-Powered Performance
- Motherboard: Gigabyte B760 D53H AC Wifi
- RAM: TeamGroup Delta RGB 32GB DDR5 6000 MHz (2x16GB)
- Storage: Kingston NV2 NVMe SSD
- Cooling: Gamdias Aura 360MM RGB AIO Liquid Cooler
- Power Supply: ABS 750W 80+ GOLD ATX 3.0
I suspect it might be a power supply issue, but I'm not sure since we don't have specific details on its output. Any thoughts? Thanks in advance!

From what you've described, it sounds like your setup is pretty powerful, but overheating may be a culprit here. It could be that something is overheating—either the CPU or even the motherboard. Also, check the RAM timings; sometimes they need adjusting in the BIOS. Reseating the RAM might help as well!
Have you updated the BIOS for the motherboard? There were significant issues with 13th and 14th-gen CPUs previously, which could lead to damage if not addressed. It’s crucial to ensure that all drivers are updated, and I’d recommend monitoring component temperatures and running benchmarks to see where the bottleneck is.
Good idea! I’ll suggest updating the BIOS. Thanks a lot!
It definitely sounds like your PSU could be failing if the entire PC turns off suddenly. Just a heads up, don't try to open the PSU yourself—it can be dangerous due to stored charges. A local repair shop may have options to test with a different PSU to see if that's the cause. The 750W should be sufficient, but if the PSU has issues, it won’t supply power reliably during intensive tasks.
I really appreciate the advice! I’ll look into taking it to a repair shop. Thanks!
The CPU might have a degradation issue since the 14900KF is known for high power draw, possibly paired with a weak PSU. The power supply you mentioned seems generic, so it’s worth checking if it’s underperforming or defective. Overheating VRMs on the motherboard are also a possibility.
Wow, that insight is very helpful! He's only had it for a couple of months, so I'm crossing my fingers that's not the case.
Thanks for the suggestion! That's a good place to start.
