I took our all my parts to use test a mother biard and it didn't work so I put every thing back in and this time I switched the cpu my pc had problems turning on but after a few try it worked so I took the cpu out and looked at my other cpu and it somehow got the pins dammage when I was swapping it I took about an hour getting the pins near perfect were with a little wiggling would fit and I took it back out to make sure any pins didn't get dammage do after I did this and placed it back into the mother board and it didn't boot so I took the country out and used the other cpu... Still didn't boot. I've tried to swap the cpu I switched the ram slots with one etc, I made sure the cables were connected firmly every thing starts up the LEDs light up on my pc and my keyboard and mouse I've also tried without USB items all the fans seem to work the disc in my harddrive spins cpu fan and PSU spins but no beep and no signal also it's started before with out a beep on some Acasions I don't have spare parts for it and no money as of now so maybe you guys can help me out
