My computer began freezing and crashing shortly after startup, usually when launching a game. The audio would loop continuously, and the system would not respond to keyboard shortcuts or other controls, so I had to hold the power button to shut it down. The next day it froze while playing a video from a hard drive, and now it powers on with the fans and RGB running but shows no image. Holding the power button no longer forces it off. Unplugging it for a while did not help. The motherboard is about five years old, and I have never replaced its CMOS battery or the power supply. The system uses a Gigabyte A320M-H motherboard, Ryzen 5 5600, RTX 4060 Ti 16GB, 16GB of Ballistix memory, and a Corsair CX450 power supply. Could the battery be responsible, or is another component more likely to have failed?

Disconnect the storage drives temporarily and try to reach the motherboard’s BIOS. If it displays an image without the SSDs and hard drives connected, one of the drives or its cable may be causing the failure. Also try the motherboard’s video output only if the processor supports integrated graphics; the Ryzen 5 5600 does not, so the graphics card must remain installed for display.
A weak CMOS battery normally causes lost BIOS settings, incorrect date and time, or trouble retaining configuration. It would not usually cause repeated hard freezes followed by a complete no-display boot. This sounds more like a hardware or power problem. Start with the basics: switch off and unplug the system, reseat the memory and graphics card, check the power connectors, and try booting with one RAM stick at a time. If possible, test with another known-good power supply or graphics card.
The listed parts make the power supply worth checking, especially since the system now ignores the power button. A failing PSU can cause unstable crashes and eventually prevent a proper start, although testing is needed before replacing anything.
Clear the CMOS using the motherboard’s jumper or by removing the battery briefly with the PC unplugged, then load the default BIOS settings. Replacing the battery is inexpensive, but it is unlikely to fix this particular pattern by itself. If the system still powers on with no display, professional diagnostics or borrowing known-good parts is the safest way to identify the failed component.
Since there are multiple SSDs, an NVMe drive, and SATA drives, test them one at a time rather than assuming all of them are fine. If there is still no display with the drives disconnected, focus on the RAM, GPU, motherboard, and PSU instead.
