Flashing power LED

RDSmith0 · November 20th, 2008, 11:19 PM

I am building a computer. I installed an ECS GeForce 7050M-M motherboard, an AMD Athlon 1620 CPU, 4 Gb of PC3200 ram and a 550 watt power supply.
(I have assembled several recently with this -- or a similar -- configuration.
When I turned on the power, CPU fan came on but the power led flashed rather than stayed on. HD power light did not come on. System did not boot.
I have not seen this one before. What do I check now?

This is a pretty standard "PC will not boot" issue. There are tons of similar posts about it.

You need to bench test the motherboard outside of the case. Remove the board from the case, place it on a soft, non-conductive surface near the case and plug in the ATX power. Leave in the CPU and RAM. Place the vid card in and connect the monitor. Connect the power. Nothing else needs to be connected. Press down hard on the vid card and use your screwdriver to short the POWER BUTTON pins. See if it POSTs.
