Your PC experiences unexpected shutdowns.
Your PC experiences unexpected shutdowns.
Hello, your PC experiences unexpected shutdowns without any clear cause. I considered the PSU might be the issue, but an online tool suggested a 560 Watt requirement, while your unit supports 700 Watts. I’m struggling to identify the problem—it occurs daily when using games, especially with your RTX 4070. I have multiple internal HDDs and SSDs. Could there be a way to detect the root cause? Thank you!
Sure, here are the full PC specifications. Regarding DDU, it can help refresh Nvidia drivers and perform a clean installation.
Details: CPU model AMD Ryzen 7 2700X, RAM Vengeance LPX 3200MHz & 3000MHz, 64GB OS SSD, Samsung 980 Pro 2TB. Additional storage includes SanDisk Plus 1TB, SanDisk Plus 480GB, and Samsung 870 EVO 1TB. Hard drives are WCD WD 3200BPVT-80ZESTO (300GB) and 900GB. Portable disks are Intenso Rainbow Line USB Device 4GB. LAN connection is Intel I211 Gigabit, GPU0 features NVIDIA GeForce RTX 4070 from ASUS with 12GB DDR6 memory. CPU cooler uses AMD Stock fans (2x bequiet) and an unknown PSU 700W 80Silver. USB extension card supports 7x USB-A ports.
I recently performed a fresh installation of Windows, replacing my disk setup, and the issues began after updating the GPU.
DDU will delete all graphics drivers allowing a full reinstall. It's the Display Driver Uninstaller, a utility. A complete Windows reset might help if you've already done a clean install, though it may not be necessary. Could you clarify the power supply unit model—such as Toughpower, TR2, Smart, etc.? Also, describe the system shutdown behavior and whether it powers off entirely.
The PSU is a Thermaltake SMART SERIES POWER SUPPLY Kabylake Ready Ultra Queit 120mm Fan Smart RGB 700W. I currently have two GPU drivers installed. For the GTX 1650 and RTX 4070, I use Studio drivers instead of Game Ready ones, since the latter don’t work well with a single game I enjoy playing.
I suspect the power supply unit is the root cause, not the drivers. A complete system failure points more toward a PSU issue. Still, your PSU appears extremely faulty and shouldn't be used. Replace it right away—check the tier list if you're unsure. https://cultists.network/140/psu-tier-list/
