A few days back my computer began shutting down unexpectedly. After some investigation, I thought a worn power supply might be the issue since it was nearing its end of life. I replaced it and everything came back to normal. Once connected, it would repeatedly enter POST mode, sometimes accessing BIOS and other times failing to start at all. Throughout this process, I changed the CMOS battery, removed the HDD (keeping the boot drive active), updated the BIOS, wiped the boot disk using ASUS Secure Erase, and reinstalled Windows. After finishing, it rebooted normally but then started cycling through POST again, preventing the OS from launching. Before this, the system had run flawlessly for more than a year, so I’m not expecting hardware faults in RAM, CPU, or GPU. Any suggestions on resolving this?
Start with just the CPU, RAM, motherboard, and power supply (connect your monitor to the motherboard). If the system won’t boot into BIOS, a component is likely defective. Use only one RAM stick and test each slot. Try connecting the CPU to another machine or a different CPU in your current setup. If none work, the issue is with the PSU or motherboard. Switch to a different PSU if possible. Eventually, if everything fails, the motherboard is the problem.
