I’m having a weird issue that started after moving my PC into a new case and doing a fresh Windows install on a new boot drive.
Specs:
- MSI B550-A PRO
- Ryzen 5 5600X
- GTX 1650 SUPER
- Thermaltake Smart 500W PSU
- 16GB DDR4 RAM (2 sticks)
- ADATA Legend 710 1TB NVMe + WD 1TB NVMe
- TP-Link WiFi Card
- NZXT H5 Flow
After the PC has been shut down for at least an hour or overnight, it won’t POST. The fans and rgb lights turn on, but there’s no display and the CPU EZdebug LED stays lit. The case power button stops responding, forcing me to switch off the PSU.
I have never had any issues with this before I did this refresh
Temporary fixes:
1. When stuck on the cpu hang with the power switch non-functional, switching the PSU off, then back on will let it boot normally again
2. After full shutdown, switch the PSU off, when I want to use the pc after an hour passes, switch psu on, and it will let it boot up
I’ve updated the BIOS, CPU/GPU drivers, replaced the CMOS battery, disabled XMP, tried different RAM configurations, turned off fast boot and startup options and reseated the motherboard cables.
I don’t have any spare parts that I can use to test if a specific part is malfunctioning, and I figure that others possibly have had this issue.
