Stop Ignoring BIOS Updates: Your PC Depends on It
I don’t care what you call this—a PSA, an explainer, or a hot take. If you leave this article and decide it’s finally time to update your BIOS, I’ve done my job.
Despite how incredibly useful BIOS updates can be for your system overall, there’s still a weird reluctance to do it unless something is already seriously wrong. That advice is beyond outdated. It’s wrong. It’s harmful. It’s time to throw it out. Updating your BIOS should be the first troubleshooting step, always.
Don’t Trust the Patch Notes
Let’s get something straight: BIOS updates aren’t part of your “everyday updates” like Windows patches or driver downloads. Most new BIOS releases won’t matter to you if your system’s humming along fine. Chipset support runs for years now. But—and this is critical—the second anything even smells off with your PC, a BIOS update needs to be the first tool you reach for.
You can’t rely on release notes to make this call. They’re terrible. Companies like Asus, MSI, Gigabyte, and others slap a few vague bullet points on a page and call it a day. You’d have no way of knowing a new BIOS could fix your issue unless you’re reading every tech forum, insider changelog, and engineer leak on the internet.
Take the Asus Prime B860 Plus as an example. Recently, it got a BIOS update that:
- Updated Intel microcode 0x114 to improve performance on Arrow Lake CPUs
- Tweaked MRC timings to solve boot and RAM-related issues
- Updated Intel Management Engine firmware (ME FW) to fix security flaws and boost performance
- Refreshed Graphics Output Protocol (GOP) for display output stability
- Updated Rapid Storage Technology (RST VMD) drivers to fix SSD problems
And that’s just the stuff we know about. If you only glanced at the patch notes, you’d think, “Meh, nothing urgent.” Wrong. It’s a massive overhaul that could fix RAM, SSD, GPU, or even CPU-related issues before they become showstoppers.
BIOS is the Foundation of Your PC
Everything—CPU, RAM, storage, GPU, networking—plugs into your motherboard. Your BIOS sits at the root of that foundation. If it’s busted, outdated, or missing critical updates, you’re going to build problems on top of problems. It won’t matter if Windows is up to date or if you reinstalled your GPU drivers for the fifth time. If your BIOS is bad, you’re wasting time patching over cracks instead of fixing the foundation.
When the only note in a BIOS update says “improved memory compatibility,” you might think, “Well, my memory’s fine.” Maybe it is—for now. But compatibility updates often patch all sorts of low-level instability issues that could affect storage, peripherals, boot times, power delivery, or PCIe bus stability.
Bottom line: if you’re troubleshooting anything weird, update your BIOS before diving into the weeds.
Modern BIOS Updates Unlock New Features
Updating your BIOS isn’t just about squashing bugs anymore. These days, a fresh BIOS can unlock new features that weren’t even possible when you bought your motherboard.
Real-world examples:
- AMD’s X3D Turbo Mode: Dropped in a BIOS update and unlocked up to 18% better gaming performance for Ryzen 9 9950X3D owners. No hardware change. Just an update.
- Intel’s microcode fixes: They released microcode updates for Arrow Lake CPUs to boost stability and even clock speeds.
- AGESA patches for Ryzen 9000 CPUs: AMD pushed new BIOS updates to fix sluggish early performance in their newest processors. Huge gains with a simple flash.
In short, you’re not just fixing bugs with a BIOS update—you’re potentially getting better CPU performance, new tuning options, expanded memory support, storage compatibility, and more. All for free. No need to buy anything.
Microcode (Intel) and AGESA (AMD) are the secret sauce here. These “CPU BIOSes” are baked into motherboard BIOS updates. They tell your CPU how to behave—how much voltage to pull, what memory timings to use, how to handle multi-core boosting—and manufacturers can tune these things significantly after launch.
Stability Problems Often Trace Back to Outdated BIOS
Some of the worst PC issues I’ve seen were solved by a simple BIOS flash:
- RAM training loops and failed boots
- GPUs not recognized after sleep mode
- NVMe drives disappearing randomly
- Crashes during gaming
- System-wide instability after CPU swaps
In almost every case, the BIOS was outdated. Users wasted hours reinstalling Windows, swapping hardware, RMA-ing “bad” components—only to fix everything with a 10-minute BIOS update.
You don’t have to live in constant fear of BIOS updates anymore, either. That risk was real a decade ago, sure. Today? Nearly every decent motherboard has recovery tools like dual BIOS, BIOS Flashback, or onboard USB recovery.
Even budget boards now carry emergency recovery systems. And if you’re super cautious, just plug your PC into a cheap UPS for flashing and you’re golden.
Let’s Talk About the Fear
Why is everyone still scared of BIOS updates?
First, it’s annoying. You need a USB stick. You have to reboot into a special interface. You have to wait, and your PC might reboot several times during flashing. It’s tedious compared to a Windows update.
Second, there’s still lingering PTSD from the “old days” when a bad BIOS flash could brick your board permanently. That was reality when:
- Boards had no recovery systems
- Power failures during flash = dead board
- BIOS updates rarely fixed anything, so they weren’t worth the risk
Today, that’s simply not the case.
Modern motherboards have:
- Dual BIOS chips: If the update fails, the backup kicks in.
- Flashback buttons: Update BIOS without even needing a CPU or RAM installed.
- Recovery modes: The board tries to reflash itself if it senses a failed update.
Unless you’re doing something reckless—like updating BIOS during a thunderstorm without a UPS—the odds of bricking your board are extremely low.
And guess what? If a BIOS update does turn out buggy, forums will blow up about it immediately. It’s never a mystery. Spend five minutes Googling your board’s model and BIOS version. If it’s dangerous, you’ll know.
BIOS Updates: Not Just for Overclockers and Enthusiasts Anymore
Updating BIOS used to be an “enthusiast” thing. Tweakers who chased every last MHz would flash new beta BIOSes to push their CPUs harder. Regular users were told to stay away unless absolutely necessary.
Today, a BIOS update is basic PC maintenance.
PCs are complicated. CPUs have intricate boost algorithms, precision voltage scaling, dynamic memory training. SSDs have firmware quirks. GPUs communicate directly with PCIe root complexes. Motherboards mediate all of this—and the BIOS runs the show.
If any one part gets out of sync, performance drops, instability creeps in, and things start going sideways.
It’s not about chasing the newest features anymore (although that’s a nice bonus). It’s about stability, reliability, and future-proofing your investment.
Quick Guide: How to Update Your BIOS Safely
Still nervous? Here’s the fast-and-safe method:
- Find your motherboard model. It’s printed on the board itself or visible in system info.
- Visit the official support page for your motherboard.
- Download the latest stable BIOS version. Avoid beta versions unless you’re solving a very specific issue.
- Copy the BIOS file to a freshly formatted FAT32 USB drive.
- Reboot into BIOS setup (usually by smashing Delete or F2 at boot).
- Launch the EZ Flash tool (or equivalent) built into the BIOS.
- Select the BIOS file from your USB drive and start flashing.
- Don’t touch anything. Don’t reboot manually. Don’t panic if it reboots multiple times.
That’s it. Ten minutes later, you’re back at the desktop with a fully updated system.
Bonus tip: After flashing, reset BIOS to defaults unless you know exactly what custom settings you want. Starting fresh avoids weirdness.
Final Word: Update or Be Left Behind
Look, I get it. Updating BIOS isn’t sexy. It’s not flashy. It won’t get you clout points on Reddit.
But it’s vital. It’s smart. It’s what keeps your PC from dying young.
I’ve seen people waste days fighting crashes, slowdowns, and random failures—all because they wouldn’t spend ten minutes updating their BIOS. Don’t be that person.
Update your BIOS the next time you even suspect a system problem. Hell, even if everything’s fine, check if there’s an update available.
Your PC will run better, crash less, and stay secure longer. You’ll save yourself headaches now and down the road.
Please. For the love of all things holy.
Update. Your. BIOS.
If you’ve gotten to the end of this article and you’re even thinking about it, go do it. Right now. I’ll wait.
