Changing the CMOS essentially restarts the BIOS back to its original settings if you’ve ever altered it. The battery acts as an unusual backup switch. Back in the day, CMOS was actually RAM and was the sole component on the motherboard with that function—now it’s more of a small NVMe storage chip attached to the board. Even though the battery isn’t involved anymore, taking it out still activates the erase button. There are several ways to reset CMOS, but the current method isn’t the most reliable. Previously, it was similar to unplugging an appliance by cutting the power cord. It felt like a guaranteed fix. Now it’s just another physical switch. I’m not sure why it still carries that name, but it does. You can usually reset CMOS in many ways, though some are easier than others. Generally, clearing CMOS won’t damage anything, though it will erase all data, including memory settings. If it’s already set, you’ll need to reconfigure it afterward to keep the machine running smoothly.
A common method to identify drive-related issues is to disconnect all drives and start from a bootable USB drive. I usually maintain a reliable Linux installation for quick checks if Windows causes problems. A Windows installation media would also be suitable.
It seems the issue isn’t the drive itself. Let’s consider alternatives—posting won’t work, the boot fails, and it’s not the hard drive. We should try a simple, inexpensive fix first before replacing costly parts, which are becoming more common. Does your motherboard support a no-cpu flash memory? That would be quite unlikely, but if we’re going through this, how long has the power supply been in that unit? More than five years?
