POST - failure.
POST - failure.
My PC experiences occasional POST failures where it freezes on the motherboard display or before any visual signals appear. This issue is resolved by a complete power-off (unplugging for 30-60 seconds), indicating a possible residual power or BIOS state problem rather than a failing power supply unit. (How can I fix this?) - The problem occurs only when I shut down the PC at night and attempt to turn it on in the morning, or when I put it to sleep for extended periods. Fast startup is already enabled.
Update - I turned off my PC at night and restarted it today without a monitor display, but all components (CPU, keyboard, mouse) were active and the motherboard debug LED remained inactive. I pressed the restart button, and the system booted. The crash log was found in the Windows DMP file.
PC components + other information,
Welcome to the forums, newcomer!
You might have simply listed your specs like this:
CPU, CPU cooler, Motherboard, RAM, SSD/HDD, GPU, PSU, Chassis, OS, Monitor.
Include the age of the PSU along with its make and model. BIOS version for your motherboard at this time.
However, since you interpreted that link, we need to know the make, model, and age of the PSU—this is the only detail that won’t appear in any app or OS unless connected via a USB cable on certain models.
How are you keeping the processor cool?
Can you get a POST when you take out the standalone GPU from your setup? We usually ask users to submit their .dmp files so we can review them. There are other ways to examine .dmp files besides WinDBG.
I currently possess a 700W 80 Plus Bronze power supply unit, approximately three years old. Regarding the post, I haven’t attempted any fixes yet since I can restart or shut it down easily. The issue only arises after extended periods—about 1 to 5 hours or longer—and I use an air cooler. At that time, it was likely overheating for some reason, but under normal conditions with low load it runs between 40-50°C in room temperature and 60-75°C during heavy usage, never exceeding 80°C.
