Fans spin but no post

infernalx · May 26, 2016

This is the 3rd PC I've built and I can't figure out what's wrong.

All fans spin, there is a mobo light, no output at all, no keyboard light.

I've gone through the list of things to check and nothing fixes it.

Asus b85M-G
i5 4690
1x8gb stick - tested and works on other system
Corsair g550m

Right now it's on a test-bench and I've tried almost everything.
Clear cmos doesn't work, different ram slots/ram doesn't work, I've cleaned it etc.

What are the last 4 digits on a sticker like http://www.guru3d.com/miraserver/images/2011/990fx-sabertooth/IMG_4499.jpg ?

The BIOS needs an update for supporting the CPU.

infernalx · May 26, 2016

alexoiu :

Only way to do it is to find an earlier CPU?

alexoiu · May 26, 2016

Either that, or ordering a BIOS chip on ebay and replacing the board's one:

Well something's fucking up.
My brother has a 4440 and his mobo.
The 4440 works on my mobo.
My mobo is on the latest BIOS but won't accept my CPU.
His mobo accepts my CPU.
I don't get what's happening, my mobo hates my cpu even though it shouldnt

alexoiu · May 27, 2016

How have you updated the BIOS?

infernalx · May 27, 2016

alexoiu :

EZ Flash 2 (I used my brothers CPU)

alexoiu · May 27, 2016

Try with BIOS updater https://www.asus.com/ro/Motherboards/B85MG/HelpDesk_Download/
under BIOS Utilities.
Check the manual for how to, or post back if still not sure.

infernalx · May 27, 2016

alexoiu :

Keeps saying there is no intel management engine interface driver even though I've installed all the latest ones

infernalx · May 27, 2016

alexoiu :

Did it with EZ Update and it said it worked, asked me to restart.
Now there is a single white _ on a black screen, did it die...?

alexoiu · May 27, 2016

Not sure. I suggested BIOS Updater. It's not the same as EZ Update.
Try clearing the CMOS (unplug the power cord and remove the CMOS battery for a minute).

infernalx :

The manual says that you need a DOS bootable USB drive

infernalx · May 27, 2016

alexoiu :

Well mobo didn't die.
It updated to latest version but 4590 still doesn't work.

alexoiu · May 27, 2016

Try the method above for making a DOS bootable USB drive, then follow the steps in the manual.
If still not working, the backup option would be ordering a BIOS chip on ebay.

infernalx · May 27, 2016

alexoiu :

I think the manual and this version are completely different.
Following the manual: bad command or filename -"bupdater".update

infernalx · May 27, 2016

Following this I get the same error as before, it's not detecting my drivers http://www.asus.com/microsite/2014/MB/New_4th_gen_Intel_processor_compatibility/#models

alexoiu · May 27, 2016

Can you post a picture of the screen when typing the command (in DOS)?

infernalx · May 27, 2016

alexoiu :

Well I'll have to try again tomorrow.

It looked similar to the one in the manual.

But just to be sure:
1) I format the pen drive correctly

2)I drag all the files from this update :Version 2108
Description B85M-G BIOS 2108 and BIOS updater
http://dlcdnet.asus.com/pub/ASUS/mb/LGA1150/B85M-G/B85M-G-ASUS-2108_and_BIOS-updater.zip

Straight into the pen drive (I tried dragging the whole folder and no "extra" folders)

and boot with it?

I tried running update.exe in the prompt but it said it can only be run in windows.

alexoiu · May 27, 2016

It should work.

alexoiu :

Managed to flash it through DOS, wiped CMOS but the 4590 still doesn't want to post. zzzz

alexoiu · May 28, 2016

Not sure what's wrong, then.
Theoretically, it should work. Not sure also if replacing the BIOS chip would solve the issue.

infernalx · May 28, 2016

Managed to fix it, what a shitshow.
We went through 3/4 BIOS update methods and the 4th fixed it.
I had to use the bios updater in Windows 10 (the one which didn't work earlier)
I fixed the intel drivers by downloading a 2013 version linked in some forum - the one on the ASUS site isn't recognized, same with the latest intel one.
Updated the bios to the latest with the windows program and it works now, pretty poor from ASUS if you ask me
