Issue with Ryzen 7700X not responding after sleep mode.
Issue with Ryzen 7700X not responding after sleep mode.
The Issue Typically this happens when the computer has been asleep for 2+ hours, but I have been able to make it trigger after a sleep session of ~30 seconds. Nothing on the keyboard lights up (No RGB, no status LEDs) & the top of the front 3 case fans doesn’t spin. All other fans (bottom 2 intake, CPU fans & 2 exhaust fans) spin. Unplugging & repluggin the DisplayPort cable doesn't do anything, the only action I'm able to take is powering the PC off via the power button or PSU switch. EZ Debug LEDs on the Motherboard pop up briefly in red and yellow - the manual suggests that this is an issue with the CPU/DRAM, but powering the machine off (Holding the power button for ~10 seconds) & back on makes everything work again. Steps I've taken so far Tried RAM tunings at 6000MHz , 5600MHz, & with EXPO disabled at 4800MHZ Disabled / Enabled ERP in the BIOS Disabled / Enabled System Fault Power Protection Disabled / Enabled Windows' Fast Startup Disabled / Enabled Memory Context Restore Disabled / Enabled Memory Power Down Updated BIOS to the Latest version (21st of October 2025 - version 7D75v1P5) Disabled / Enabled CPU -0.05v undervolt (Have had this enabled since building the PC in December 2024) Disabled / Enabled CPU built-in graphics Ran Windows Memory Diagnostics (Clean on both sticks) Ran DISM ScanHealth, CheckHealth & RestoreHealth & Ran SFC /ScanNow (Clean) Changed sleep settings within Windows (Currently only S3 is enabled , S0 / S4 (Hibernate) / Fast Startup disabled) Updated CPU drivers, GPU drivers, Chipset drivers to the latest versions I haven't tested each one of these setting individually, however I've tested multiple combinations of each. Settings in bold are what I'm currently using, and the issue still persists.

I was originally on the BIOS from 26/12/2024 & only updated after the issues started. The only significant hardware change I've had since purchasing the PC is a new power supply, due to my MSI power supply's fan failing. This was many months before the issue started, and I didn't re use any cables. I understand that Hibernation is an alternative option, but I don't want to use my SSD's cycles on that. Even if it is a minor thing it'll still bug me in the long run. Besides, I'm looking for a fix, not a patchwork solution. Unfortunately it wouldn't surprise me if this was an MSI board specific issue. I've had tons of problems with the quality of their products in the past (The aforementioned power supply issue, as well as 2 seperate monitors both failing for the same reason after ~9 months each). Given my track record with them, this seems around the sort of time I'd be expecting one of their products to break. The only daisy chained fans are the 2 fans connected to the CPU fan header, each other fan has its own fan header on the motherboard. Windows doesn't show any error logs relating to this - apart from the typical "The system has rebooted without cleanly shutting down first." when booting back into Windows after the error. This is because the system is unable to get to Windows when waking from sleep. Would appreciate any help or advice, thanks.
No, you don’t have to let the PC shut down completely. You can turn off sleep mode entirely and just put the monitor to sleep instead.
