Im posting this as a last attempt to fix this problem man, i've tried so many things i've scanned across google hoping to find something that would help me out. My issue started 2 days ago after a night of gaming hard. I decided i wanted some rest and so i actually decided for once i would shut down my computer rather then put it to sleep just cause. So i powered it down went to sleep woke up next morning to find that it didn't wanna turn on ( gamers worst nightmare). Now i picked it up put it on a night table and had a look at it. I looked to see if any cables were loose or if anything was spilt on it. i noticed the motherboard had power because it had its LED's lit. I proceeded to change the outlets( nothing yet) i cleared Cmos nothing. So then i took to youtube on my phone looking for ways to diagnose what was wrong. At first i thought it was my PSU so i got my old computers PSU and hooked it up nothing, the leds only powered up. so well then i ruled out the PSU and thought about the mother board. i re seated all the power cables running from the PSU to the mobo and nothing. Well here comes the weird part of the story, so i searched the web for like 2hours and had not touched the computer then decided to touch the 12v cable that powers the cpu and the lights on the fans flickered and they themselves began running but immediately stopped within 2secs. I tried to re create this with no success so i decided to keep searching for more information. Not 30mins later i sighed and hit the Start button and holy god it started. Now begins my current issue, since its start i didn't recieve a display i probably restarted it about 5 times and then it stopped working with randomly powering itself and turning off like when your lights flicker the fans would run and then stop for a period of time. i decided to power it off and take off the power cord, in which time i decided to take out the CMOS battery and let it drain for a while. After what was like 1hour i turned it on again finally, but received Q Codes and still couldn't post BIOS. The Codes i've gotten are A2,AE,B4, and A0 at this very moment its on A0 which to my understanding is a good thing but still no display. I did happen to see BIOS 2 times last night only when i decided to try to plug in my old Grahpics card from like 2004 into it and see if it would work and IT DID, until i tried to input the right settings for my memory(ram) and cpu frequency. when it saved the settings and restarted it just gave me a, A2 code again. SInce then i've flashed the bios updating it to the latest one and aswell as downgrading it back to what i had it at i believe it was 1604. I've cleared CMOS like 20times. tried new cables on my HDD's new powers cables for the HDD, tried different sockets on my Sata ports for it. nothing it just doesn't give me a display. At this very moment i have that graphics card still in it, if any of you have any ideas or if you believe this is Done i guess im just gonna spend 3weeks with out a mobo and RMA it. This truly sucks.
