After doing everything again, I unscrewed the mobo out and did the Jumper trick by moving the pin and taking the cmos battery out for longer then 30 seconds and when I put the mobo in I made sure that the screws were not over tightened.
Nothing has been solved for me. I have done everything, in every solution and trouble shooting steps. I even pulled out the mobo, and cleared the cmos. Updated the bios to 1403 and still no post. The odd thing is. It is like it froze my USB ports. Unless I remove the power. Even with the computer off my other keyboards will stay lit up. Even another type of illuminated keyboard. I can power off the system, unplug the keyboard, and when I plug it back in..it lights back up. Like it was never removed.
I had this problem, however when I left only 1 stick of ram (I have 3 2GB Corsair dominator) then the computer woul boot. (please note that I had previously tried shuffling the sticks around but always using at least 2 and I would still get the black screen) with only one however it would boot.
I solved this by reseating the CPU. It looks like the receptacle is too big (design flaw i would say) and the contact with the CPU is not always perferct.
I think its safe to say that if your computer boots with only 1 stick of ram reseating the CPU will solve your problem.
I'm having the same issue as this guy was but I can't seem to fix it. It was working fine. I went to the kitchen, came back and the screen was black. When I boot and enter setup it randomly decides to show my drives, or not.
My P6T SE + 920 set up was working fine but now I get one short beep then another short beep on power up, Ive tried reseting the cmos jumper, taken the battery out everything but I dont get any dispay output, my graphics card is an HD5970, I sincerly hope its not the problem
Does anyone know what the problem is?! Thanks in advance for any replys.
I have a P6t with the exact same problem the only thing I have found that seems to work is just turn it off for awhile and try again.
Sometimes I have to reset the CMOS which I wish was on switch on front. I still do not know exactly what is wrong but when it does come back my video card settings have all changed and not all 3 of my monitors or recognized so I have to go back and re configure
I too would like to know what this is and how to fix it.
