CPU no longer compatible after Bios Flash

Hi there!

My PC was experiencing some sporadic crashes, so I figured that I would flash my Bios (on an Asus M3A) for the first time in case the bios had become corrupted or in hopes a bios update would fix the crashes.

I updated my Bios from version 0806? to the newest bios version, and upon startup my screen now reads "CPU Not supported. System will shut down in 15 seconds."

I'm pretty sure I can't flash my Bios again by other means because I can't get any further than this point, and obviously my CPU's compatible because I've been using it for years without issue.

Any help would be greatly appreciated.

    Hi, please give me the exact model name of your motherboard. Clear the CMOS ( you can follow the instructions on how to clear the CMOS in your motherboard manual as well), make sure the PC is turned off, unplug the power cord from the Power Supply, remove the battery on the motherboard for one minute and put it back. power up system go to bios by pressing the DEL key and, Reload the Optimized Defaults, save settings and exit.

    I believe that Asus M3A as said in my original post is the exact model name (Is they're more that you're looking for?) and I cleared CMOS right away with the jumper last night, and all that happened was I lost my date and time.

    I can't get into Bios to set any defaults because of the CPU error message & my PC shuts down after 15 seconds.

    Well unfortunately the bios update version 1206 which is the one you should have updated with? may have been corrupted during the update process. What you can also try to do is to remove the CPU from the socket, clear the cmos again and replace the CPU. The crashes you experienced was probably caused by a faulty PSU, CPU, memory, corrupted drivers and software or the motherboard itself.

    EDIT: Your motherboard supports ASUS CrashFree BIOS 3 meaning you can recover your bios with a failed flash. Your motherboard manual will explain the steps involved on how to do this.

    I'll go try out Crashfree Bios and attempt to restore my Bios. If that works, then I owe you many thanks! and even if not, thank you so much.
