Hello, I joined this forum because something unusual is occurring. After a long pause—around a week ago—it consistently shows "American Megatrends" before the BIOS loads (1). It always places my boot drive in the third slot, so I have to move it back to the first position. It's quite bothersome that my settings don<|pad|>, and especially after ten years of use, it never changed. The problem didn't seem linked to my hardware specs or performance until recently. Before I mention details, about a month ago my computer attempted to boot from an unreadable USB drive. I had to power it down quickly, and I suspect it caused damage since now I can't use my card reader. If anyone could help identify what's happening with my PC, I'd really appreciate it! Specifications: - CPU: 64-bit Intel Core i5-4460 (4 cores, 3.20GHz) - Motherboard: ASUS M52AD_M12AD_A_F_K31AD - RAM: 2x4GB DDR3 at 1600MHz - Graphics: Nvidia GeForce GTX 1660 6G (StormX Palit) - Storage: Kingston 128GB SSD (boot drive); Western Digital 1TB HDD; Kingston 1TB SSD (latest); CD/DVD player; Card Reader (still recognized but not working). - Power supply: ACBel PCA022-ZA2G 80 Plus Bronze 228W

Have you considered changing the CMOS battery?

Is this genuinely a matter? I believed it was just another joke online. By "replacing," do you intend to alter it?

After a decade, the battery might stop working. This piece explains problems linked to a dead CMOS battery: https://www.hp.com/us-en/shop/tech-takes...nd-replace

The CR2032 battery maintains the BIOS settings even when the computer is off. When the PC remains connected and the power supply switch stays on, the motherboard receives a 5V standby from the computer and transfers control to the battery, preserving those settings and keeping the clock active. If you disconnect the computer or switch off the power source, the battery must supply the clock, causing it to drain over time. Certain motherboards may rely solely on battery power for the clock, leading to quicker depletion.
