Your computer shuts down and restarts a few times before starting up.
Hello, your PC is experiencing intermittent power fluctuations before it starts up. After a sudden power cut, the system turns on and off several times during boot. Once it powers on normally, it runs through three to four cycles before stabilizing. It has been functioning well since then, even when you shut it down manually or via Windows settings. This issue seems related to your BIOS or the new PSU. If anyone can clarify why this happens and suggest solutions, that would be helpful. Apologies for the unclear English.
Certain boards perform what's known as false starts after clearing the CMOS. They usually boot up, run memory checks, then power down repeatedly to identify all boot devices before shutting off again. This process repeats until they function properly. I haven't encountered such behavior during a power outage, though it's possible in theory. It might help to test the CMOS battery condition, as a failing one could cause the system to activate and operate normally, but each reboot would reset the BIOS settings, potentially triggering false starts.
Yes, that might work. It could simply be an oddity of your motherboard, even though I haven't encountered one like it before.
Is this an outdated system? The motherboard seems to be the issue. I think the first thing to inspect is the CMOS battery—it might be draining and preventing the system from saving settings properly. If that's the case, other checks like RAM connections, storage integrity, and OS corruption should follow. But overall, the CMOS check is the top priority.
It's not an old PC from the 9th generation. I have two RAM sticks—one from Corsair and another from Hyper X.
Regarding the CMOS battery, I've noticed failures within a year, though they typically last about ten years in general. I also own a motherboard with a rechargeable CMOS battery; after not using it for a year, I had to keep the power supply active (but the computer was off) for several days to recharge it.
