Infinite restart, standby mode, RX 7900 XT?
Infinite restart, standby mode, RX 7900 XT?
Hello everyone, just wanted to check if this is typical behavior.
I only noticed it under specific conditions: the monitor went into standby mode, and there was a power outage for the PC (cause unknown). After that, the PC would restart endlessly unless the monitor was turned back on.
Here are the details of this setup:
- Antec NX220 RGB LED Gamer Case
- Intel i5 10600K 4.8GHz Hex Core CPU with Hyper-Treading
- Intel Stock LGA1200 cooler
- Gigabyte B460M D3H motherboard
- 24GB 2133 MHz Dual-Channel RAM (8GB+4GB Corsair DDR4)
- ASUS AMD TUF Radeon RX 7900 XT OC 20GB GPU
- Antec HCG EXTREME 1000 Watt power supply
- Samsung 500GB EVO 860 SSD, installed games
- Samsung 980 PRO 1TB NVMe SSD, operating system, installed games
- Samsung 980 PRO 2TB NVMe SSD, installed games
- Western Digital SN550 2TB SSD, installed games
- Ugreen NVMe~PCIe adapter
- Seagate 2TB ST2000DM008 HDD (backup games)
- Seagate 2TB ST2000DM008 HDD (backup games)
- Seagate 10TB ST10000VE0008 HDD (movies)
- Microsoft VHD Blue Ray image drive
- Intel 1000Mbps Ethernet
- D-Link 300Mbps USB WiFi
- Genius GX Scorpion K220 wired USB RGB keyboard
- XGR Wired USB LED gaming mouse
- Logitech Stereo speakers
- LG 24-inch 1080p 144Hz monitor (supports 2160p [4K] @ 120Hz)
It’s not a problem, but I’m curious if others have experienced this with similar hardware and if there are any known fixes.
Appreciate your help.

Other than the described issue in the thread title, the pc has no other issues, but I like to, with tom hardware members help and support to figure this out and maybe try and resolve this before I'm faced with this again next summer.
Note: Infinite reboot only present when pc is Idle when ambient is near 40c.
Note 2 : Infinite reboot 2 only present when the pc has sudden loss of power when the monitor was in standby mode and stops rebooting when monitor is turned on.
It seems the assembly process is becoming excessively warm. The current build temperature of "X" plus 40°C ambient equals no PC reboots. When the temperature reaches "(X + 1)" plus 40°C, reboots occur. Consider experimenting with methods to lower internal temperatures. Perhaps disconnect some HDDs temporarily to see if it helps. Check if this changes the outcome. If feasible, capture photos of the case interior—cables, drives, fans, coolers, etc.—and note the direction of airflow. Share these images here via imgur (www.imgur.com > green "New post" icon).
This configuration seems unusual for RAM. It might be contributing to the problem. It's recommended to use a compatible set rather than mixing kits. Note that Corsair is the sole supplier of their ICs from various vendors, and even slight differences in PCB revisions can matter. A 2x8/2x16GB DDR4-2666MHz kit with low latency would be ideal. What BIOS version does your motherboard run? Check if removing the front panel improves temperatures by enhancing airflow.
If there is any chance of damage, I'm not trying to fix the PC itself. My goal is to resolve this problem, especially after last summer. Maybe by swapping out the specific part that's causing it, with your assistance, since I haven't identified the exact reason on my own.
The 5-year-old PSU previously handled the same PC with a RX 64 Vega and HD 7950, but now it seems to work well with only the RX Vega 64. It appears to supply enough power for the new build as well, drawing around 400 watts with the RX 7900 XT alone, without any problems during continuous use or gaming. The BIOS version F7 is stable, RAM is functioning properly, and it passes all memory tests. It’s unclear what might be causing this, but replacing the RAM seems like a strong possibility. Could be something else is involved, but this is the main concern. Please let me know if you see any other issues elsewhere.
It seems the two posts were merged unintentionally, as they address completely different problems with this PC. I noted it’s okay to handle them separately.
Issue one concerns temperature management (the 40°C problem).
Issue two involves GPU and monitor performance (just an observation after upgrading to RX 7900 XT).
So the current single post now covers two unrelated issues.
Thank you for bringing this to attention so we can assist others better.
Remember that power supplies offer three distinct voltage levels (3.3, 5, and 12) for different system parts.
An issue with any of these voltages can severely affect the host system. For example, voltage to RAM...
Do you own a multimeter and understand how to use it? Or do you know someone who does?
Note:

This isn't a complete test since the PSU isn't under load.
Still, any deviation from the expected voltage signals the PSU as a potential problem. (Also consider that the PSU is already several years old.)
PSUs are built with an End of Life design, meaning they may reach or exceed their lifespan—leading to instability during high demand or difficulty maintaining required voltages.
You've checked the PSU several times and everything looks fine at idle voltages (3.3, 5, 12, etc.). I understand it's not as straightforward as using a multimeter, but I don't have one handy either. I'm hesitant to take it apart again just to test. Should I concentrate on the PSU for this problem, or is there another factor at play? The main concern right now is the 40C issue during idle, especially since the PC keeps rebooting endlessly—even after a full hour off, it stops only when night falls and I can restart it for gaming.
Review Reliability History/Monitor and Event Viewer.
Both tools might record reboot-related issues if the boot sequence progresses sufficiently.
Examine the boot process directly—see what actions occur during startup.
Verbose mode could appear as a configuration setting in the boot menu options.
The process may slow boot times and could be inactive by default or disabled at setup.
Is there a way to regulate ambient temperature during the day, especially if it goes above 40°C?
Perhaps a small fan would help circulate cooler air near the machine.
What is the typical ambient temperature range?
