Hi, guys, I am having an issue with my system and could use some help. Here is my issue when I have all 4 sticks of ram in the system will not boot, no beeps just power up fans but no monitor signal. So then I took all 4 sticks of ram off theMB I get beeps then I put 1 stick in slot number 1 I get beep boots to bios mind you I have not installed an HD CD drives I try all 4 sticks of ram in slot 1 and all 4 boots up. when I put 2 sticks of ram in slots 1 and 2 the system boots up. I then put 3 sticks of ram and I get no boots I try each stick in slot 3 I try each stick slots 4 no boot. I also try slots 1 and 3 for dual boot and no boot. I switch PSU that I know is working and had all 4 slots filled with ram and no boots. I also notice that when I do boot having ram in slot 1 and 2 and I power the system up the PSU starts then turn off for a sec then starts and I get to boot up. I think the MB is bad anyone thinks I am right or what else should I do?

It sounds like bad ram slots and it does happen. I've seen many boards over my time working on them exhibit those same symptoms.
