Motherboard died

[KamikaziFly]

I have to assume the MB died. Since it overheats in 15 seconds from cold boot, then overheats each boot afterwards in 3-5 seconds. It does not beep nor state what is wrong.

It's really hard to find what is the best replacement board out there for me since I have no PC and just a smart phone. Could someone help guide me?

My current dead MB is:
Asus M5A99FX pro r2.0
https://m.newegg.com/products/N82E16813131851?_ga=2.38521060.632998776.1515795212-867275120.1515795212

I have an AMD fx 9590 black 8-core, 220-watts.

The MB heat sinks are scalding hot, the CPU is just hot, the video card was just hot when it died.

By over heats do you mean that the PC just switches off.

I think that's an AM3+ socket, if I'm not mistaken. Maybe an Asus Sabertooth for replacement?

Anyway if your mother board is getting super hot very fast you definetelly have an issue with it. You are correct. My normal temps of my motherboard are not to much over ambient temperature or about 28C-32C. Even when my CPU is being heavily stressed the temp sensor on my motherboard doesn't hit 50C.

There really isn't anything to buy for AM3 anymore; it's been dead for many years already.
It's really time to just move on.

How do you know the Board alone is the culprit? Could be that the CPU is dead, or even something else. Take the setup to a shop/tech and have them diagnose the whole rig.

Ya. The PC just switches off.

Wow, that's pretty cold in comparison to my temps of 87c when playing an intensive game.

Okay that is the BIOS that does that. If it happens that fast it could be fan failure on your cooler. Or a PSU problem. If the motherboard was completelly toasted I don't think it would even boot in the first place. It would not even power on..It would just be dead.

I am talking mainboard temp..Not CPU temp.

Yep, am3+ socket.
Can you suggest a good socket to search for? Or a CPU that is low wattage to keep the cooling down?

I am having trouble finding good alternatives, atm.

Oh, that sounds right. What do you suggest to fix the BIOS? Cause I got into BIOS this morning and just looked at it for 15 seconds before it turned off on me.

I'm wondering if somehow the BIOS auto-updated in the last 6 months since I had no problem prior.

I wonder if it would be possible to get a better BIOS on an old USB drive around here, and flash it prior to post? Or if that would only make it part way and switch off leaving the BIOS dead in the process.

Your BIOS is probably fine. Its just protecting your PC. It detects you have a problem either temperature or voltage and shuts your PC off.

Did you make any changes in BIOS that could have made your PC unable to run like changing ram timings or the CPU multiplier or voltage. There are actaully many things that could make it unable to boot up. Basically did you change anything why you where there.

Nope. I try my hardest to not fix things that aren't broken. I tend to buy CPUs that do not need over clocking, since I've never had a good experience when over clocking attempts 15-20 years ago.

My fan was overly loud suddenly last August so I installed a new fan program in win7 pro to control it better. The old program just seemed to be missing, and all its temperature/fan control settings we're gone. The new program also didn't seem to be keeping its settings after a month or two, and I had to set them again in September or October, or both. And now that I think about it, the fan wasn't unbearably loud when it died yesterday. So maybe the settings kept getting wiped.

Reset the BIOS/CMOS; then press and hold the MemOK! Button and then enter the BIOS and re-check.

BIOS can't auto-update

Motherboard this old, the CMOS coin battery is probably dead; and if so, Motherboard wont boot, but shuts off.

Hmm. Yesterday evening when I tried to boot it, on the post screen it said to press F1 to enter settings due to that the settings we're over clocked incorrectly.
But since I refuse to over clock, I assumed it was either false, or something was attempting to automatically over clock settings.
Either way, it switched off before I could press F1, and I haven't seen that msg since.
In fact, pressing F1 does nothing and the last time I could even see anything printed to the screen the only choices were F2 and DEL. Which took me to a BIOS screen where I could use my mouse. Which also switched off in less than 15 seconds as described in my post way above.

Yea battery is dead then

K, I'll try that. I was looking for the battery to pull, but really couldn't find it.
I'm going to have to look in the MB manual how to reset the CMOS/BIOS. I do have a spare if the battery is dead.

Thanks for this info!

[Bad 💀 Motha]

What is there to know? Its the same as on most PCs, pull the battery and power cord, press and hold case power button for 15 secs, cmos is reset....

Replace the battery with a new one; CR2032

Its located right under the primary PCIE X16 slot

[Viper]

Yes it appears that your BIOS settings are messed up and that is why your PC won't boot. Bad_Motha could be right on track that your CMOS battery has died. It is usually a small watch battery located on the motherboard.
