I've recently upgraded my CPU, not knowing it was incompatible with my BIOS: another site had told me that my AMD FX 9590 would work with an Asus M5A97 R2.0 but this clearly wasn't the case. I swapped out to my old CPU and booted the PC up, "Overclock failed". I reset my CMOS and then tried another boot but the system completely shuts off after a second. I've had a look through the boot thread but everything was compliant with it so I'm not sure where I go next.

Computer specs:

  • Motherboard: Asus M5A97 R2.0
    CPU: AMD FX 6200 (old CPU)
    GPU: MSI Radeon 390x
    RAM: Corsair Vengeance Low Profile 8GB (2x 4GB)
I'm not sure which components are relevant so just ask if I've missed something essential.

P.S This is the first time I'm creating a thread on this site so I'm not 100% sure if I've posted it in the correct place, apologies if so. I'm just so desperate to get my rig fixed.

If you can get your system to stay on without a CPU then it really wont be too risky, and even in the event of a power failure you can probably do it again, but keep this as a last resort. Remember to use the USB 2.0 port if you try. I understand your hesitation, and there are a lot of scary stories around regarding BIOS. Do you get stuck in a boot loop with both CPU's now?

Have you tried just powering on without a CPU and updating or even loading default BIOS as normal? (That's safe, I promise).

To do a hard reset of BIOS, move the jumper cap from the first two pins to the second and third ones to the right for about 15 seconds when your power cable is disconnected then move back. This will reset memory controller and really clear...

The system keeps turning off, trying to update the BIOS might be risky? I've read that if I try and update the BIOS and lose power, it will most likely brick my PC?

Yes, you are 100% right in that regard and right to be cautious, but what is most likely happening is its stuck in a boot loop. Basically your PC is checking the hardware (POST or Power On Self Test) and restarting. There is a way though.

Remove CPU, and if the system stays on, use the BIOS flashback by using a USB stick with the latest version on. There is a guide here, and you need to name the file M5A97R20.CAP... http://event.asus.com/2012/mb/USB_BIOS_Flashback_GUIDE/

Check the manual for more instructions http://dlcdnet.asus.com/pub/ASUS/mb/SocketAM3+/M5A97_R2.0/E8046_M5A97_R2.pdf?_ga=1.268279243.451823312.1482730913

When you say "Remove CPU", do you mean that I should completely take out the CPU and try to power up the system then? Alternatively, could I pull out the ATX cable? From past experience, I couldn't get the system to turn on at all without the ATX cable being plugged in. Apologies for asking for specifics, I just want to make sure that I don't fluff anything else up.

I've got the old CPU in but the system keeps powering off. The furthest I've got is to the BIOS and then it completely shut off. I'm worried about updating the BIOS because it keeps switching off; I don't want to brick my motherboard.

Yes, boot up without a CPU installed, or if you'd rather an easier way, do as dish_moose syas and put old chip back in and do it the normal way. I forgot you had a CPU that was compatible with the board.

Only do it if the system stays on though. If not, you will have a paperweight instead of a motherboard.

When I switched back to my old CPU, that's when the system started powering off straight away. When I submitted this question, I was referring to this problem with my old CPU as I had already discovered that my new CPU wasn't compatible with my board so that would explain all of those issues. Should I still try and power up the computer without my old CPU installed or is the motherboard a goner?

I took out the CMOS, left it for a few minutes, and put it back in. I then reset the BIOS settings to default but the problem still remains.

OS corruption wouldnt cause a boot loop.

If you look on the mobo website you'll see the FX processors need a later BIOS version, but if its happening with your old previous CPU after the new one failed then its more likely BIOS config.

A CMOS reset doesnt always do a full reset, and it may be that you nees to do a hard reset with the jumpers, but that board has a ton of features and you should check the manual to see which you can take advantage of in this system.

A BIOS update may still be a good idea, but I am on my phone right now so cant re-check manual to see what other options to explore.

I'm not sure if I would be able to do this since my PC will likely power down again.

I've took a look at the manual myself but I'm not 100% sure to what I should be looking for. The CPU configuration section has a few options but I'm not sure if it's anything that can help my situation; I'm only an A level computer science student so there definitely could be something that I've missed. When you're free, would you mind taking a look as it seems I'm short on options. A BIOS update seems a little to risky and maybe unnecessary with my old CPU and the CMOS reset doesn't seem to have helped but I could try and do the hard reset that you mentioned?

To do a hard reset of BIOS, move the jumper cap from the first two pins to the second and third ones to the right for about 15 seconds when your power cable is disconnected then move back. This will reset memory controller and really clear the board BIOS. If you dont have a jumper cap on there just use a screwdriver to short (touch both) the 2nd and 3rd pins instead.

For an even softer approach, you could attach an onboard buzzer to the system warning speaker to check for error code beeps but you can only do this if one came with the board or you have one handy.

Also ensure all cables are attached fully and the cooler is attached to the cpu_fan header or it will fail to boot. You dont need any hdd's or graphics cards attached. The less peripherals the better.

Other than that, as you cant even access your BIOS there isn't a lot to do so hopefully one of these methods will shed some light.

I've booted the system up without the CPU in, seems to stay on, but I'm getting no display. My keyboard and mouse aren't working either. I'm not going to be able to perform a BIOS update with no display: any reason to why this is happening?

Well now I'm completely confused... How do I perform a USB flashback without the display? The manual states that I need to download the flashback wizard and use that once I've inserted the USB with the BIOS update on. Is there something that I'm missing?

You do it by using the BIOS flashback button on the board itself. From the manual..

USB BIOS Flashback allows you to easily update the BIOS without entering the existing
BIOS or operating system. Simply insert a USB storage device to the USB port, press the
USB BIOS Flashback button for three seconds, and the BIOS is updated automatically.

You have to manually put the BIOS file on the USB as I said above.

BUT I was looking at your old CPU (the FX6200). Your new CPU (the FX9590) is not supported on that board... https://www.asus.com/uk/Motherboards/M5A97_R20/HelpDesk_CPU/

Try doing a CMOS reset via jumper pins with your old CPU installed. You may need to re-flash your board to even make it compatible with your old CPU now. Check the BIOS version on the board itself next to the model name.

There isn't a button on my board, the manual even states that I need to use the BIOS flashback wizard.

I've just realised that I have a different motherboard to what I posted in the specs. I actually have a M5A99X EVO R2.0 and have been reading from that manual. Not sure how much difference that makes though.
