I possess a preassembled CyberPower PC purchased from Best Buy. Its warranty lapsed several months ago. This problem has occurred multiple times before, typically resetting once or twice before I finally managed to get it running, so I didn’t think it was a major concern. I just returned from a two-week vacation recently, and I suspect a power outage might have caused the issue—when I arrived, clocks and the security system needed resetting, which could be linked to this now persistent problem. I should also mention that the machine only initiates posting after being left off for a full day or longer. It jumps straight into the BIOS, then either loops again or eventually stops sending power to peripherals like the monitor, keyboard, or mouse, even though the PC still gets power.
You might check the CMOS battery and swap it if needed. While doing so, turn off the PSU, which also resets the CMOS settings. It’s a convenient way to address the issue. If this doesn’t work, the board or PSU may be failing. Without extra testing gear like a replacement PSU or motherboard, pinpointing the problem becomes tough.
You followed the CMOS reset instructions. You also tried some basic hardware checks by removing and replacing certain components (like the PSU, motherboard, or CPU), but the issue persists. The system keeps restarting inside the BIOS or failing to send signals to external devices.
How did the battery performance look under 3v? Or 3.2v or somewhere in between? The three components you haven’t checked are still unknown, so I’d start by testing the power supply first, but I suspect the board might be the problem. Without a way to confirm, it’s just a guessing process. Sorry, there isn’t a simpler method to figure this out.
I didn’t check the battery voltage, just removed it, waited a while, then put it back in. This is my first attempt at fixing hardware issues, and I’m only seeking help because I don’t want to pay for service from geeksquad. My friends and I, who aren’t really skilled, thought the BIOS needs updating. After clearing the CMOS, a red light appeared on the motherboard after the post-loop.
Well a bios could become corrupted, perhaps a flash could do the trick. You have a 50% chance it recovers the board. I mention swapping the board as a last resort because it's easier to test everything else first. In example swapping the processor if a buddy has the same platform. You could Google up common. Issues with your particular model and see if something pops up too.
