The PC fails to start following the BIOS update.
The PC fails to start following the BIOS update.
Hey everyone, I just faced an issue with my CPU. It experienced significant clock-speed reductions during games. I attempted various fixes, but nothing resolved the problem. Someone suggested updating my BIOS, which I didn’t do. After following their instructions on their website and YouTube videos, I started the update. When the download reached 50-70%, I lost consciousness for about a minute. Upon returning, my screen went dark and remained so for 20 minutes. I’m convinced the power cut or a USB port issue caused it. Once I powered off and restarted, the black screen persisted (no boot). I tried a BIOS hard reset, but it didn’t help. My PC still doesn’t boot. If I power it on now, only the CPU light stays for a brief moment. What do you think? Could my motherboard, CPU, or both be faulty? My setup includes a Ryzen 5 3600X, Corsair Vengeance 32 GB RAM, 2400Mhz Palit RTX 3060, MSI B450M PRO-VDH, and it doesn’t support USB flashback.
If the update stopped mid-process and the board lacks a bios flashback function, along with CMOS resets and power cycles failing to resolve the issue, it’s likely the board is permanently damaged. Replacement would be necessary. When a board becomes non-functional without a flashback feature and CMOS issues, there’s nothing effective to fix.
It includes a CMOS reset feature (meaning the reset using those small connectors), but performing that action didn't produce any changes.
my idea is the pc was going through reset cycles after shutdown to verify everything was working, which might have stopped it. if that’s likely, the board could be damaged. i’m considering removing the CMOS battery for about 20 minutes, then reinserting it and trying to restart. i’ll also try reseating the CPU, as this has helped before with 5x3d and b550 models.
It's a straightforward Ch34A1 programmer fix, likely cheaper than replacing the board. You can easily find instructions online for updating the BIOS chip with it.
I was surprised to learn they created reprogramming kits for bios chips without needing to take the board off. That’s pretty impressive. Usually people say once something is bricked, there’s little you can do, but it used to involve replacing the chip and wasn’t worth the hassle, especially on budget boards. I’ve never explored other possibilities before.
You're looking for clarification on handling the BIOS chip. It seems you want to know if removing it is necessary or if connecting it through the JSPI1 connector is an alternative.
some external bios flashers include a connector that links to a specific port, as indicated by the IC lanes. you can see this from the available options. an example I discovered is https://darkwire.com.au/shop/ols/product...95-eeproms. however, you'll need the cable from https://darkwire.com.au/shop/ols/product...-and-cable to connect it to your setup. additionally, you can purchase those that connect directly to the chip's pins. this is the Ali Express product. https://www.aliexpress.com/item/10050036...!USD!US%24 3.59!US%24 3.16!!!!!%402103242516813014791976072ec7c1!12000026480125312!btf&_t=pvid:649751c6-ba56-47e6-940e-18fb9bf0c8e6&afTraceInfo=1005003609533117__pc__pcBridgePPC__xxxxxx__1681301479&spm=a2g0o.ppclist.product.mainProduct with the clamp, you can attach it directly to the bios if they're single-chip. it's feasible to divide bios and install data on multiple chips. probably you should be able to use the jspi1 port by reversing it and clamping onto one of the adapters, though i haven't tried it myself. it really comes down to making the connections work.
