Hate to bother you all but I need to get your input on my latest problem. I have a GA890FXA-UD5 rev 2.1 that has been working flawlessly. Ran it last night turned it off (windows 7) and all was well. Just went to turn it on and NOTHING. When I am looking at the mb the blue lights on the power, reset and oc buttons are lit. When I press the power on (mb button) the lights on the mb just flash the case fan starts/stops with the blinking. NO BEEPING from the speaker nothing else works. I removed the power plug from the mb and used an ULTRA power tester and it said it was fine and all led's lit. Replaced and nothing. Tried another power supply and the same lights lit but still nothing. Power supply is modular so removed all the power leads so only the mb power supply lines were connected (in case a device was shorted dragging down the ps) - no joy.. It seems to point to a mb problem at least to me. WHAT other test or diagnosis should I perform that will further narrow it down to the mb or power supply? Anything/place on the mb that I should look at to see if something has happened? Lastly, IF another mb is in the cards is the new 990fxa one to consider (remember reading some bios problems and voltage problems??)? IF not what other mb should I consider. LOOK forward to hearing from anyone on getting this darn thing up and running. THANKS...
UPDATE: Removed both memory sticks - no beeping - nothing. Removed the 12v cpu and mb power connectors from mb and placed them in ps tester. PS came on and all fans and peripherals started up = ps good. Question now is how does one determine whether its a mb or cpu problem as ps is now ruled out?? Don't have another cpu to swap out with. When re-connected all of the above still applies=NO BEEPINGS no nothing.. Please let me know your thoughts..THANKS
There are two ways to indicate if its a CPU. Most motherboard will flash something like "Bad CPU, replace" when you turn on your computer and two i would try to find another CPU if you have any laying around which is a little hard. However its very rare for CPU to just go bad unless you overclocked to high or over voltage which will burn out the CPU. I have this similar issue like you a long time ago, and I did a combination of disconnecting my Hard drives, PSU to the motherboard, resetting CMOS, taking all the RAM out of the computer except for one and placing that one stick on another DIMM slot. And just praying hoping it would work, and then all of a sudden it worked.Sometime this happens because you MB found a short somewhere and it goes in to a safe mode. And it could be in this mode.
What I would honestly do Is I would take your motherboard out of your case and place it on a cardboard box or a surface that non conductive. Then I would unplug everything from the motherboard RAM, Video card, Hard drive, fans, and reset your CMOS. Take the battery out and leave it out for a couple of minutes. Then place the CMOS battery back in the computer, then plug your video card in, hook your monitor in to your video card or on board card, plug your PSU back in to your MB, take one stick of memory and place it in a DIMM slot and do not hook anything else in to the computer. You want it to POST and to see if it truly did short. If it posts then I would logically say something shorted out your MB. I hope that helps. This is what I did exactly and it worked
