I removed the hard disk of hp G61 and replace it with the hard disk of hp G9. The G9 worked perfectly but i removed the memory to check it and then i replace it smoothly. I put the original hard disk of G9 and i tried to turn it on but nothing diplayed on the screen knowing that the fan and hard disk is working and the capslk is blinking every 2 or 1 second. So what could be the problem please help.
THANK YOU IN ADVANCE.
