Black Screen at POST, no BIOS load, video proof


my system;
intel i7 920 d0 3.8ghz
asus p6tse
sapphire 5870 1gb
team xtreem 6 gb 2000 mhz 9-9-9-27(but actual settings is 1600mhz 7-8-7-21, command rate 1T )
thermaltake toughpower 750w

just as you can see at the videos, there is no BIOS load at the start of the computer. when i did not overclock system, no problem occurs.

my actual BIOS settings are also at the video. this problem seems like cold boot. I don't understand. I use 0805 BIOS.

part 1;
part 2;
part 3;

I know the videos are not good job, but this is only best way to explain my problem well.

  1. just clear the CMOS.
  2. ok. it is a way not to get black screen. but How can I get 3.8ghz or more? did you watch videos? What to do after I have cleared CMOS?
  3. Reset your bios, to get to 3.8, oc your cpu inch by inch, and determine what your computer requires for voltages all across your motherboard,
  4. If you've tried all the obvious and still stuck in power saving mode; this is what I did
    After installing a new cpu fan w/cooler, I had disconnected all wires ; as it was necessary for the install of fan. I had two wires slightly wrong.
    1) The power cable which is the 4 holes with plastic on it; I had it in reverse! Clip faces outside. Ok fixed.
    2) Then those 3 little thin 2 pin wires..reset, power & hdd were incorrect. The negative wire (black) should face outside. Then insert the reset wire in the 2 pins closest to the one missing a pin. then plug in the power wire in the next 2pins; so they're touching. Now SKIP two pins & plug the HDD wire into the last pins; so there will be a space between the power & HDD wires. VOila!
  5. I have tried all memories by starting computer one of them. It did not help. The same problem occured again. I have also changed places of RAMs. #1 to #2, #2 to #3, #3 to #1. I did not help too.

    If you want to know, My CPU temp is 77C under load. 40C-45 no under load. I use thermalright extreme 120 ultra.
