Are there problems with cold boot when the power supply is turned off during the night?
Hey everyone, I’m dealing with a strange cold-boot problem and need some advice.
Hardware:
Biostar
B450GT3 (last BIOS)
Ryzen 5 3600
RTX 4060
16 GB DDR4 3200
MWE Gold 850W
If the power supply is turned off overnight, the next startup shows no display with the RTX 4060. The fans spin, everything powers up, but nothing appears on the monitor.
Restarting several times or avoiding turning off the PSU at night results in a normal boot.
An older GPU (R5 220) works perfectly even after a cold boot.
I’ve added a mobile audio speaker debug and it produces 8 short beeps (VGA init error).
I’m unsure if the problem lies with the motherboard or the GPU.
After trying to force a display, everything runs smoothly. I’ve tested various software to check the GPU and found no issues. Everything seems fine.
What I’ve done so far:
- Updated and downgraded BIOS versions
- CMOS battery replacement
- Reset BIOS configuration
- Checked HDMI and DP cables
- Swapped monitors
- Purchased a new PSU
- Used different cables
- Cleaned all PCIe slots
- Reinstalled GPU drivers with DDU cleanup
- Tried many other solutions… but I’m still not sure.
Edit: The issue was with the GPU.
Do you have Windows Fast Startup turned off?
Check if you often choose Sleep or Hibernate instead of shutting down completely. Sometimes USB devices fail to recover from Sleep mode.
I disable hiberfil.sys right after installing Windows on my desktop PCs, but keep it active on laptops.

If problems persist, try installing Linux on a different SSD to determine if the issue lies with Windows settings.
I turned off fast startup in both Windows and the BIOS. I never choose sleep or hibernate, just a full shutdown. Hiberfil is also disabled.
I'm beginning to suspect the PSU might not be delivering enough power for the RTX 4060. It's a very unlikely scenario, but I've noticed some issues after switching from my old Corsair TX850M (2021) to an MSI A1000G. The problem started with occasional restarts when both CPU and GPU were under heavy load. During video conversions, the system drew 400W for the 3060 and 430W for the 4070. My previous PSU was ATX 2.x compliant, possibly with a 120% current limit on the +12V rail. The new MSI PSU is ATX 3.x PCIe 5.x compliant, featuring a 200% short-term current limit on the +12V rail, built to handle GPU spikes. A review on Tom's site for the Version 3 model of your PSU indicates it has a 116% limit on the +12V rail, which isn't ideal for NVidia GPUs that can spike up to 200% for brief periods.
The MWE Gold 850 V3's specifications show a trigger threshold at 140% for the 3.3V rail, 142% for the 5V rail, and 116% for the 12V rail, with an OPP threshold of 120%. While an 850W PSU like my old TX850M and your MWE Gold 850 should be able to manage GPU surges, real-world experience suggests otherwise.
One reason for the stricter 3.x standard was to improve short-term current handling for NVidia cards. I acknowledge it's improbable that an 850W ATX 2.x PSU would refuse to start with a GPU, especially during demanding tasks like gaming or rendering, but exceptions exist.
Would the new PSU match the exact model of your previous unit? TL;DR: If you can borrow or replace an ATX 3.x compliant PSU of at least 850W, it could be a viable alternative.
I had a nearly ten-year-old Corsair CS550M. Now I own this new one: https://www.coolermaster.com/en-global/p...ar-series/
No one has ever asked that... why do you switch off your power source?
I never switch it off since I don’t want to have to dig under a desk to activate it whenever I need my computer.
I own many PCs and servers. If they were all plugged into the mains together, the vampire power—including monitors—could easily surpass 500W.
With my provider billing US $0.34 per kWhr, the expenses quickly add up.
I use remote control mains switches. Press the right button on the handheld remote and a PC plus monitor will turn on or off.
In any case, all my individually switched 13A mains sockets are located in a long industrial power distribution strip behind my main computers. Just reach behind the three monitors and flip a switch. Simple.
Bang goes my theory it could be a PSU issue. Your latest MWE is ATX 3.1 compliant and should handle GPU fluctuations. The main challenge remains identifying the problem. A real test would involve getting another RTX 4060 or running the GPU in a different system. Maybe a friend who repairs computers or a local shop could help. I could possibly use any mid-range NVidia card from the 3000, 4000 or 5000 series. If the issue continues, it’s likely not with your RTX 4060. In my view, older CS, CX and CV PSUs worked best in standard office PCs with just an iGPU. With a high-power PCIe card installed, these PSUs might struggle. Since your CS550M is ten years old, I’d consider replacing it or avoiding critical use if it fails due to aging components. I’m skeptical the warranty covers such a risk.
Hey, I've gotten tired of it and just placed an order for a new graphics card, GPU, and CPU. Will let you know once it's here.
