Power issues ?
Recently my power operates at around 50% of its capacity. When my ASUS PC starts up, I see a BIOS screen asking me to enter Setup. I press F1 and then F8 to boot, and it works properly. I have an ASUS PC that's nearly five years old, but I'm unsure about the type of power supply it uses (the System Information doesn't clarify). Should I replace the power supply?
If the CR2032 battery is depleted, the BIOS may lose certain configurations and ask the user to intervene (Press F1). You could observe the system resetting the clock to an arbitrary date in 2019, among other things. When functioning properly, the CR2032 maintains the Real Time Clock. If the time is incorrect, Windows will reset it using a network server, but after shutdown with a dead battery, the PC again loses track of time. The F8 key could be used to choose the boot device. With a weak battery, the BIOS will miss the boot order list and the initial entry might not be your operating system drive, which is why it displays F8. A working CR2032 should read approximately 3.25V. I swap batteries when the voltage falls below 2.50V. A discharged cell will show less than 1V.
Yes, the date and time on the PC changed last week. Now, today the PC won't start at all. Yesterday it worked but after I left and came back, the screen was black and pressing the mouse or keyboard didn't work. I plan to replace the CMOS battery. Will it not power up if the time is incorrect?
It's mainly about the situation when the CR2032 battery is depleted; the computer frequently struggles to start and may even refuse to begin. Incorrect time or date configurations rarely stop the system from launching, provided the battery remains functional. When acquiring a used motherboard without a battery, I replace it with a new one and verify the BIOS settings. The time and date are often set to outdated values from a long time ago. After adjusting them and saving the changes, I proceed with installing Windows.
Under normal conditions, Windows updates its clock via "Internet Time" if the BIOS time is incorrect. If all else fails, installing a fresh battery can revive the system, though you might need to adjust certain BIOS parameters that were previously overlooked. A common issue involves the boot drive being mistaken for a network, optical, or floppy drive instead of the intended Windows installation.
Occasionally, after losing memory, the BIOS defaults to booting from "Network," "Optical Drive," or "Floppy Drive" (in older systems), rather than the Windows drive. You must identify and configure the correct Windows drive as the primary boot option, ensuring you save your settings before exiting the BIOS.
In summary, when an old machine appears unresponsive, I test the CR2032 battery voltage using a digital multimeter within the 20V DC range. It’s straightforward: connect the positive terminal to the top of the CR2032 and the negative to the chassis. If the voltage drops below 2.5V, it’s time for a replacement. A flat battery typically reads below 1.0V.
Note: When installed properly, the '+' symbol on the CR2032 should stay visible. The negative terminal stays concealed inside the holder. Always place the CR2032 correctly to keep it visible.
You might attempt the "paper clip" method, though it won't expose specific issues (high ripple voltage, malfunctioning overload protection, or power limits).
Check the +12V (yellow), +5V (red), and +3.3V (orange) rails using a multimeter after turning off the power cables connected to the motherboard and any storage devices, USB ports, or fans.
If the PSU fan fails to activate, it doesn't necessarily indicate a failed power supply. Many PSUs require sufficient power output or heat dissipation before the fan starts.
Voltage readings beyond these ranges suggest a need for replacement, though testing without load isn't ideal.
Aresgame PSUs have a poor reputation; consider purchasing a higher-quality unit even if the AGW650 functions.
Review of an 850W Aresgame.
During the process of installing a new CMOS battery, the screen displayed for just a moment and the fans failed to activate. After replacing the CMOS battery, does the system automatically adjust the date and time or requires manual input? To find out the appropriate PSI size, what information should I consider?
Have you run the "paper clip" test yet with the power cables disconnected from the motherboard. If not, we still don't know if the PSU is "working" or not. It could be on the point of catching fire. If you read through this post on Tom's, you'll see the AGW650 is regarded as junk. https://forums. You're lucky to have got 5 years of use out of it. Replace it now before it explodes. It may already have damaged your motherboard beyond repair. As I've already explained, you can set the time manually in the BIOS after replacing the battery (best option) or connect the computer to the internet and wait until Windows loads the correct date from a time server. You could also update the time/date manually as soon as Windows starts. Some programs throw up errors when the date reverts back to some distant time, several years ago in the past, when the CR2023 battery dies. If you're lucky, when you buy a brand new (high quality) PSU, your computer will still work. Fingers crossed. If you're unlucky, you might have to replace the motherboard, if the Aresgame has destroyed it. There are numerous "PSU Tier Lists" but try this one: https://cultists.network/140/psu-tier-list/ If you choose something in Tier A (High-end), Tier B (Mid-range) or Tier C (Low-end) you stand a good chance of getting a decent PSU. Please don't buy anything in Tier E (Avoid) or Tier F (Replace Immediately). It's just asking for more trouble. Provide us with a complete list of your PC components. Then we can advise on a new PSU. At the very least we need to know the exact model (part numbers) of the CPU, motherboard and GPU card (if fitted). The motherboard part number is usually printed somewhere near the PCIe slots (up in the corner). For a low end PC, another (good quality) 650W PSU should be fine. For a more powerful PC, you might need 750W or higher, but if your existing system has been running on a flaky Aresgame 650W PSU, I doubt it pulls more than 250W. Good luck.
