The computer freezes during sleep mode, and the fans start spinning immediately afterward.
Hey everyone, as mentioned in the title, my PC freezes when it goes into Sleep Mode. Right after shutdown, fans kick in and everything stops working, including power buttons and reset options. It had been running smoothly for months until I installed a new drive on Black Friday. The drive was initially placed in the lower PCI4 M.2 slot, but I moved it to PCI3 and then switched it to PCI4 for better performance.
Since then, whenever I put it to sleep—especially after switching power sources—it would trigger a BSOD and then restart fine. I used Windows Media Tool to reinstall Windows, formatted the drive, and fixed the error code 0x80300024. After removing all drives except the two M.2 ones and retrying, it worked. I updated Windows and restarted several times without issues.
Now I’m trying sleep mode again, but it’s the same problem: fans speed up, then shut down, restart, and freeze completely. No display appears on the screen. After installing Windows 10 and updating BIOS to enable Secure Boot and TPM, it still won’t boot. It says there are no bootable drives. I disabled TPM, enabled CSM, and it finally started. I’m not sure if this is the main issue or just a symptom.
Your latest Windows version likely set up with the MBR during installation. You can switch it to a GPT partition by searching online for instructions. I handled this for my wife’s computer in just 10 minutes. How many monitors are you using? I’ve heard that some AMD systems with sleep freezing issues can be fixed by disabling adaptive sync.
I won’t go into detail about everything, but you’ll need to check your BIOS settings and confirm the boot sequence is correct. You should always place your primary drive in the first slot. Even if everything looks right in the boot order, there’s a risk it might still try to use the top slot. If you have the OS drive in slot one, performance in slot two should remain sufficient for reading/writing operations. Unless you’re determined to adjust things, just revert your drive back to slot one. If you prefer to test, you’ll likely need to experiment to make slot two take priority. Regarding sleep mode, custom builds often encounter problems during shutdown, which can cause crashes due to recent Windows updates. I’m not sure if a fix exists yet since I stopped using it because of these issues.
Consider this initial approach. My advice may be more detailed, and I might not have fully understood it within the primary OS drive or if it wasn't partitioned.
I have two monitors with resolutions 3440x1440 at 165Hz and 1980x1080 at 75Hz. Please let me know if I can set it to GPT, enable sleep mode, and use adaptive sync. If these settings don’t work, I’ll move the drive back to the top slot and reinstall Windows. I’ll keep you updated.
I cant believe this, I did what @Harmsway1283 suggested, from MBR to GPT, I got an error, tried to fix it got another error, said fuck it and restarted, got the "Not boot drives, please insert a bootable drive" so I figured the boot got wreck, since I was going to reinstall windows anyway I decided to do what @zipspence said and swap the drives back. Was getting ready to install new windows but it actually booted into windows, with TPM and Secure boot already enabled, I checked on the windows health app, then tried sleep mode again and it worked and woke up perfectly. Now I'm just waiting for the windows 11 update to drop and seemingly its all back to normal. Funny thing is, I didn't even install windows when I put this PC together, moved the drive from my old PC to this and it just worked, but now moving it from 1 port to another in the same PC bricked it. Anyway, thanks guys, If I could Id split the between the two of you.
It's understandable, the system often behaves as expected even with correct settings. Windows handles hardware swaps quite smoothly. You can easily move drives between machines without needing major changes. Still, it can become quite challenging at times. Many manufacturers recommend placing the operating system in the top slot, but this might change in the future to allow more flexible drive ordering. Custom coding for boot sequences is possible, though it adds unnecessary complexity.
