Hiya all long time viewer first time poster here in desperate need of help...
Set-up
Asus a88xm-plus (latest bois)
A10-7850k (4.0ghz)
2x4gb 2400mhz ddr3 radeon r9
2x 60gb corsair ssd raid0(primary)
2x 1tb HDD (storage)
500w corsair PSU
Windows 7 x64
My problem:
PC started up fine and after downloading all updates of windows 7 and other bits n bobs steam/games etc. And powered down my pc for all the updates etc after rebooting bois couldn't find my os.... Strange I no but sometimes wired things happen but this is where it gets worse.. so after messing with my bois rebooting pressing f8 to choose boot drive still nothing. So I decided to wipe all HDD/sdd and default bois settings on the next boot up I had nothing no post no logo no beeps nothing. I have tried everything
Apu still getting warm on so am guessing that's OK??!
The ram I have tried each stick in each slot and tried different ram in each slot. Still no boot....
Different PSU to rule it out which it did. And tried different monitors in different ports HDMI/VGA/dvi.
So now am stuck when i boot the pc the monitor comes on but its just blank for where the asus logo should come up
Is the board dead? Do i
need a new bois chip? Is there anything I have missed???
Sorry for long story but I would just let everyone no every detail.

Hiya normh just tried changing CMOS battery which made no difference and for the changing HDD there's nothing plugged in ATM just the board 12v(4pin) and the 24pin plugs CPU and a stick of ram just to try n boot

Try removing the cmos battery for 10 mins (while system is off) then replacing it.

Cmos battery is the large silver disk on the motherboard, can't miss it.

EDIT: How old is the motherboard? is it new or second hand? Where did you get it from and how long ago did you order it if you bought it recently?

if you have no hdd you will not boot past bios. if the cmos is not reset you will not even get to bios. try the above to get to bios then set to boot from disc. install the hdd and boot from disc to verify the monitor is not the issue. after that load a new copy of windows. if you can not load at all but can get to bios it may be the hdd.

Depending on which country you are from, it is likely to be a legal requirement for the product to be fit for purpose for a limited time. The 2 weeks should be less than the max time and this product is NOT functioning how it should be. Therefore (Atleast by UK law) the seller MUST give you a full refund (Including postage costs).

Hopefully we can fix the motherboard, but if it comes to that, then now you know.

For the returns, the seller only has to offer a full refund and pay for any postage that was charged to you. To replace the item I am unsure if you can request next day delivery or not, you will have to look that up.

It is possible when you restarted the computer for the final install the process of flashing the bios chip was interrupted. This basically means the motherboards BIOS is corrupted and cannot boot. To fix this a new BIOS chip must be installed however BIOS chips are mostly soldered in and are difficult to replace. If you do not feel comfortable re-soldering the BIOS chip you will need to return the board.

As a last ditch attempt, you can try to repair the bios with a USB stick. You will need to search a guide for this as the process is pretty long and complicated, I'll be honest, you are unlikely to have any luck with this method and it could cause more problems in the future. It is worth returning the board in my opinion.

Typically USB keyboards/mice don't respond until the BIOS boots. PS2 peripherals respond faster.

Hiya all so from last night the last ditch attempt was change CMOS battery just incase the battery failed but nothing. left on overnight thinking is might force its self back to back-up bois but yet another fail. I also thought I might try a pci-e graphics card but still same thing is happening boots fine just no post so I have now ordered a new msi a88xm gaming motherboard with help if a refund for this motherboard should be here 2moz so lets pray to god it wasn't the apu -_- am not throwing the bad board away as I also ordered a bois chip to see if that will fix it

I had an identical problem. Replaced the MoBo and the CPU twice. Still receive the one long beep and two short beeps which the MSI web site says indicated inability to initiate video. I tried three different monitors, two different 500W power supplies, two different sticks of RAM. All of which are working, video monitors, two of them were DVI. Lights come on, HD's and CDROM all run up; fans come on, but still the one long beep and two short beeps indicating video failure. I've ordered a PCIe video card and will try that next. I suspect a systematic failure in quality control if this is common to other users. BTW, I've been building computers for 30+ years (starting with a Heathkit H89) so am a very experienced rig builder. I went into the video output jacks with my o'scope and a jumper cable I have made up previously, and saw no activity other than a change in voltage when the rig was powered on, then the trace dropped back to zero. This is the very first ASUS MoBo with which I have had trouble, so am quite surprised. MSI has not replied to my emails (of course). Anyone got ideas?

I know this sounds insulting to a 30 year builder, but are you sure the CPU and Mobo socket match?

It's just the chances of two sets of mobo/cpu's failing is so low... It certainly sounds like an on board graphics issue. What CPU were you using? Were you using a PCI-E GPU, if so what was it?

Not insulting at all! Thanks for your insight. I am using an AMD Athlon AD760KWOLHLBOX 760K Richland 3.8 FM2 Socket 100Watt CPU. I've plugged the monitors directly into the on-MoBo video sockets. Have not yet installed a separate graphics card. Thanks for the assist!

Have you ensured a secure connection with the CPU power cable from the PSU?
Seeing as the Athlon doesn't have any onboard graphics I assume you are running on the motherboard graphics which means that the motherboard is the issue (probably). The chance that two motherboards fail is small, but it is still there. You may have to get another motherboard to see if that finally gives a solution.

I THINK I'VE GOT THE SOLUTION TO THIS PROBLEM

I had the same problem when installing the last of the updates for Windows 7. The newly built PC had very similar specification to what you have quoted ( i.e. A88XM-Plus, A10-7859k, SSD & 2400Mhz Ram).

The changes in the Bios manifested the problem and not the updates, but I'm not geeky enough to explain why to you.
On the other hand, the solution is to clear the RCT RAM and the instructions to do so are on page 1-12 (section 1 page 12).
Just in case you haven't got the manual to hand I'll describe the procedure to you briefly.

There is a 3 Pin jumper that sits behind the USB 3.0 power connector that sits on the outside of the motherboard, or just to the left of the 1st 6Gb Sata connector. There are actually two 3 Pin jumpers in that spot, but the RCT RAM Clear pins sit together, side by side, without a gap. They other 3 Pin connector is positioned between the RTC RAM Clear pins and the USB 3.0 connector.
You should now see a JUMPER CAP that sits on the two LEFT Jumper Pins, Ok now turn the computer off.
Move the jumper cap from the centre and middle pin to the centre and right pin.
LEAVE IT ON THOSE TWO PINS FOR 5 TO 10 SECONDS, and then put it back.
That will have cleared the CMOS memory of date, time and system setup parameters by erasing the CMOS RCT RAM data.

NOW THER IS SOMETHING TO WATCH OUT FOR, when you turn your computer back on it will boot to Bios into default settings.
However, when you load your operating system if you attempt to use Windows Update or surf using a browser you are going get errors that will stop you from doing so.
This looks and feels quite serious and is frustrating but it's a really simple problem.
The time and date have been reset to the time of manufacture, so the months and years that the operating systems collects from the Bios will also be out of sync. All of Windows Updates and browsers updates (such as Flash Player) function on time stamps, so you have to change the time and date before you can continue with your life.

If that solves it, glad I could help.
