I just put together my PC last night, and when it came time to power on, it seemed like everything was working just fine, CPU fan was on, front case fan turned on, and I added my laptop harddrive and I think that was even spinning, but when I hooked up to my TV via HDMI there was no display. So I tried a traditional monitor hookup and that didn't work either. The 4 pin on the mobo is connected, I triple checked the connections from the manual, but I guess I could still have made a mistake somewhere. Any ideas?
ECS A55F2-M3 Amd A55 Socket FM Motherboard

(2) Centon 4GB DDR3 1333MHz
Thermaltake V2 Plus Mid Tower Case with 450W PSU
Is everything new ? Yes I bought everything except my Harddrive, which I just removed from my laptop.
Do you use onboard gpu ? I believe so, here's the specs from the Processor:
CPU Type Desktop
Processor Interface Socket FM2
Processor Class A6-Series
Processor Speed 3.6GHz
L2 Cache 1MB
Additional Technologies AMD Turbo Core Technology
Unlocked Multiplier Yes
Instruction Set SSE
Integrated Graphics Core Yes
Graphics Core Speed 760 MHz
Integrated Memory Controller Yes
Did you try to hook up basic vga ? Yes
Do you hear any beeps when computer power on (you should hear 1 beep if everything is fine and you have a pc speaker.) No beeps, I plugged in the PC speaker, then reversed it just to check I didn't plug it in backwards. I do hear noises when I hit the power button, but no significant beeping
Take out the memory and try to power on, if it does but your hear beeps, it means ram is the problem but it should be compatible. I will try this today after work and report back.
#1 Tested each memory stick individually, no beeps upon powering on. Cleaned the sticks still nothing.
#2 Pulled CMOS battery, and did the jumper thing, still nothing.
#3 pulled Mobo out of case and placed on cardboard, inspected Mobo could not see anything wrong.
#4 Checked for bent pins, nothing.
I just solved my own problem!! But I thought I would post to let any future Googlers know what saved my build. I notice a red switch on the back of my power supply unit and it was on 230V, so I switched it to 115V, and bingo, computer booted right up!
