Asus Z87-Pro BIOS reset problem

saif uddin · Oct 6, 2013

After I built my PC, I turned it on and it seemed to power up just fine but nothing loaded on the monitor screen. I made sure that everything was connected properly several times but still no change. I tried leaving the PC running in case the BIOS was just taking its time to load (20+ mins) but still no change. I also tried a different monitor, both work on other systems, but still no change. I tried using only the hard drive in the build and then only the SSD but no change in either attempts. I tried clearing CMOS but still the BIOS does not appear. I'm not sure if my CPU is dead because I do not know how to test that and I do not know any one with a compatible motherboard for my CPU. Can anyone please help me fix this?

My PC build:

i7 4770k CPU
2 x 4gb Crucial Ballistix Tactical Memory RAM
Asus Z87-Pro Motherboard
MSI gtx 770 4gb Gaming Edition Graphics Card
Be Quiet! Dark Rock Pro 2 CPU Cooler
2TB Seagate Barracuda Hard Drive
128gb Corsair Force Series SSD
Corsair HX850 PSU
Silver Stone RV04 Case

I had a very similar problem recently, it was a complete pain in the ass to troubleshoot.
Try removing the CMOS battery from the board, the short it with a paperclip.
Then reseat the ram, but only put one module in.

After that, take the kettle lead out from the back of the system so there is no power, then hold down the power button for about 30 seconds.
Plug the lead back in, then see if it fires up.

Good luck, keep us posted.

use the usb flashback port put the newest bios on the mb. in the bios set the primay display to peg/pci not ipgpu. i8f it set to ipgpu it boot from the onboard video first. in the bios set your ram to xmp profile and mb speed to standard.

Sorry I should have mentioned that I'm a complete noob at this. It's my first time building a computer and the methods I mentioned for trying to resolve my problem were all from the internet. I don't know how to do the thing you suggested with shorting it with a paperclip... =/ Is there another way you could explain it? Dumbing it down is the way to go lol. I've used a paper clip to test the PSU by sticking the clip in the motherboard power cable.. If it's anything like that I may be able to try what you suggested. Thank you for responding btw. I didn't expect anyone to respond so soon.

Not a problem,
-take the side panel off of your case
-locate the cmos battery
-look at which side is facing up and remember it
-remove it with a flat-head screwdriver or other tool
-you need to touch the positive and negative sides (top and bottom) with a conductive material such as a paperclip or tweezers for around 5 seconds
-put it back in the computer.

Did you need anything else explaining in terms of discharging the capacitors?

Good luck.

So I should put the new BIOS update on a flash drive and if I plug it into the flashback port it will automatically update the BIOS? (I don't know how it works :??:

) The BIOS doesn't load so I won't be able to update it normally..

Thanks! I'll try that during the day because I got Uni at 10 so I need get some sleep. I'll let you know as soon as I've tried it (Hopefully while I'm on my new computer

)

on a fat 32 formatted usb stick download the bios file
http://www.asus.com/Motherboards/Z87PRO/#support
then put it into the bottom usb port under the ethernet port and press the usb flashback button on the mb. with the mb off. if you dont need to rename the bios file the usb bios updater will start flashing and blink for 2-3 min then turn off. if you have to rename the bios file under bios tools is the asus bios renamer. drop the tool into the same folder or place as the bios file and run it.

look on the motherboard it has a led display with 2 digits on it... turn the pc on and watch it flick though them till it stops.
if it doesnt reach FF then take the number/letter combo you see and post it here.
this is you bios error code similar to the bios beep code except gives a better idea of what went wrong when you compare it to the error number list.

It says 55. I told a friend of mine about the problem and he said to check the manual to see what 55 meant. The motherboard cannot detect the memory I installed even though I made sure that they were firmly placed into the A1 and B1 slots. My friend suggested I try them in the A2 and B2 slots to see if it works in those slots but since I've run out of thermal paste, I'm going to have to buy some more tomorrow and try again then. My CPU cooler is huge so I have to take it off to take out the RAM. All the parts for my computer are brand new.

HEXiT · Oct 7, 2013

if you have new pase on the cpu it wont matter if you remove the heatsync to replace the ram. just make sure when you press the HSF down that you rotate it left and right till it starts giving resistance. this is it telling you, you have pushed out all the air trapped in the paste that was there previous... 1s you have completled your tests or got windows to boot. you will see that there is likely little or no difference to the temps. putting new paste on every time isnt a necessity. its done for the most part for the extra 1'c of potential cooling when the system is working...

so for now just go ahead remove and replace the cooler as needed till you get your system to boot.

that being said what ram make model, timings and voltage did you choose for your motherboard... if its high voltage say 1.65v then thats likely the issue as the board may be trying to boot it at 1.5v (the ram should allow it but i had issues with ocz ram doing this).

saif uddin · Oct 8, 2013

Thanks for all your help everyone. I have kind of solved the problem. I'm not sure why but when I put in only one RAM stick in the B1 slot and then started it up, the computer booted up finally (The manual said to put it into the A2 slot if using only one RAM stick but it didn't work in there). Though I have a new problem now. After it booted up, it displayed the RAM being at 1333 Mhz but it's supposed to 1600Mhz. The RAM is Crucial Ballistix Tactical Memory RAM 1.5V (8-8-8-24). I bought 2 x 4gb sticks that came together. The manual for the board said anything below 1.6V for RAM is safe.

in the bios under ai tab is dram speed. motherboard default to have that set to auto. when they do the mb reads the eprom of the ram and uses the default speed in the eprom. under dram speed if you switch it to xmp profile it read the max sped of the ram speed in the eprom and set your mb speed for you.

it seems only one dimm slot is working on my motherboard so i'm gonna have to replace it.....

When removing the CPU, check the socket for bent pins.

alexoiu :

My CPU and motherboard don't have pins or a socket for pins but it is a common problem people seem to come across. Thanks.

saif uddin · Oct 10, 2013

smorizio :

Thanks I'll keep that in mind when my new motherboard comes

alexoiu · Oct 10, 2013

No pins for the CPU socket? How does the CPU make contact with the socket?
Take a closer look to this picture (roll the mouse over the socket). You'll see the CPU socket pins: http://www.emag.ro/placa-de-baza-asus-socket-1150-z87-pro/pd/EHLB0BBBM/

Its a flat surface. Here's an image of how it looks: http://www9.pcmag.com/media/images/324112-intel-core-i7-4770k-front-and-back.jpg

alexoiu · Oct 10, 2013

For the CPU, yes, but I'm talking about the socket - the location on the motherboard, where the CPU gets seated. It has pins that come in contact with the CPU. A bent pin could create issues like the one you're experiencing.

saif uddin · Oct 10, 2013

alexoiu :

I'm very likely to be wrong since i have zero experience in building computers. If you advise me to try a possible fix then i'll try it. I've ordered a replacement so for the time being i'll have to hope this new motherboard is without fault.

HEXiT · Oct 10, 2013

sounds like you have a doa motherboard saif. your getting it replaced so that should solve it. as for the ram just go into bios and turn up the ram multiplier till it reads 1600 i have the same ram and it runs quite happily at 1.5v but if you need to you can go to 1.6 without any issues.

Since you'll have to remove the CPU anyway, just take a close look to the CPU socket. See if there's any bent pin.

Thanks HEXiT and smorizio, as soon as the new board arrives i'll try that (that is if the new one works fine that is).

A friend of mine has the PC right now so I can't take a look atm but I don't think that's the problem since I've been able to start up the PC properly now and it detects it fine. Just the RAM slots giving me grief. But I will take a look once I get the motherboard off him so I can return it and then update the thread of any issues I come across.
