The computer turns on,fans all fire up,but no video of any kind screen is black ,bios does not show ,no beeping of mobo..A number of weeks ago a problem started where restart will not work ,had to cold boot computer each time ,but computer had video.
Components = Asus m2n slideluxe mobo ,AMD x2 5600 ,ocz 2g pc800 ,antec 620w truepower ,evga 8800 gts ,antec 900 case ,so lots of cooling.
Tried so far = reset cmos ,reset ram ,video card ,all components.. reset all plugs off power supply ,tries pci-e secondary slot ,swapped videocard from other (working) machine, swapped out different monitors ,keyboard and mouse ,disconnected all HD's ,so only fans and videocard on bootup...the only mobo beep I get is if I leave off the power cable to videocard...

HI, Clear CMOS or remove CMOS battery, Press the on off switch for 30 seconds. Now go to BIOS setup,and set bios fail save default,and press F10>enter.If the problem same change the RAM if you have a spare. http://www.computerhope.com/help/phoenix.htm
If the cpu was bad- nothing would turn on--be sure the cable is good-- also be sure the VGA is enabled in the bios- since you cant see the video you have to reset the cmos setting--unplug the unit and remove the cmos battery-reinstall after one minute and check for video
Does the computer beep, to tell of booting progress?
Is the new MoBo really new? What about the video card?
Try different RAM. Bad RAM will not let a computer boot.
Try booting the MoBo out of the case: lay it out on wooden surface and plug in power supply and monitor, then turn on. Listen for beeps, HDD cranks. Also watch the screen.
Come back after doing these checks so we can isolate the problem.
Remove and reinsert the dimms reseat the video card also put everything back and try agailn If this dont work reseat the cpu and repeat steps above
If the above fails to fix
If it will boot into safe mode and use the standard vga as you did before and restart and try to reinstall the drivers You are sure you installed the rilght drivers for your OS It may be that the card is not compatible wilth your mobo.Try checking compatability list for your OD
