I am wondering if you have a hardware problem.


What is the make and model of the computer or motherboard?


What drives are connected to what ports?


Assuming motherboard graphics, I would strip the motherboard down to the 
motherboard, CPU, and memory for troubleshooting.  If you do not have 
motherboard graphics, then also leave a graphics card.


Test the power supply with a hardware power supply tester.


Has the computer been unplugged and/or the power supply turned off for 
long periods of time?  If so, perhaps you should test or replace the 
CMOS battery.  Symptoms of a weak battery include CMOS checksum errors 
and CMOS settings changing or getting lost.  Getting locked out of Setup 
is another possibility.


Get the service manual and look for a "BIOS Configuration Jumper Block", 
or some such.  Use that to get into Setup and restore factory settings. 
  Note the following warning in my "Intel® Desktop Board DQ67SW 
Technical Product Specification January 2011":

     CAUTION

     Do not move the jumper with the power on. Always turn off the power
     and unplug the power cord from the computer before changing a jumper
     setting. Otherwise, the board could be damaged.


Is the firmware up to date?


Have you tested the CPU and memory with memtest86+?  For 24 hours?
