I have p7p55d e pro , I5 750 . 2X2 1333 KINGSTONE , GTX 470 .
I had to travel with my pc so I took it apart and I carried it in my hand bag to make sure it is safe . when I arrived , I re-installed it again .
Surprisingly , the mother board keeps rebooting for ever and no boot at all , no monitor data , nothing at all , just a short beep .
but the cpu led turns on (red ) just before it restarts , so I thought it's PSU problem (OCZ 600 ) so I bought GIGABYTE 720 , but still the same problem .
I have deleted the cmos using the deleting jumper to reset the bios and still the same problem .
I tried to reinstall my computer out side the case to make sure there is no short and still the same problem .
I have unplugged all cables from the mother board except for cpu able and mother board cable and cpu fan and turned the computer by activating power jumper , but the still the same problem .
I tried to run the system with only one ram , but still the same problem .
THE MOTHER BOARD DOESN'T RESTART ONLY WHEN I UNPLUG THE CPU CABLE , BUT OF COURSE NO BOOT OCCURS .
ANY HELP PLEASE !! MY HEAD IS GONNA EXPLOOOODE
This is exactly my problem .
Also , I have been overclocking to 3 (not much ) , is this a problem ?...I believe clearing CMOS should reset the default frequency .
GUYS , I noticed that the short beep doesn't occur when I disconnect the SATA POWER CABLE . When I connect it one single beep occurs .
I tried to run the computer with no rams at all , it gave me the same short beep .
I expected it to give the no ram beep code but it did not .
Help please , I am loosing my mind !!
