Hi! '''++Sohaieb++''' I have read all the troubleshooting you have done but I not read that you clear the CMOS with the jumper. 1) Look for the jumper at the bottom of the mobo it should say a very tiny '''CLR CMOS''' or something similar. 2) Change the jumper to the clear position by moving the jumper to the other side of the 3 pins. 3) Remove the '''CMOS''' battery, the '''RAM''' memories and '''Disconnect the power''', wait 1 min. and put everything back again. 4) Turn on the PC. I hope this work for you PC. If not your motherboead it may have been damaged and you need to replace it with another '''''(Remenber always use a brush for clean the interior of PC the liquid and computer not mix''''' '''''and watch out for compressed air cans they can cause equal damage to PCs''''' '''''if misused)''''' ''''''''''
