i have an asus striker 680i and im tyring to build my own computer, i put everything together and i just get a blank screen i need to know if the RAM could be a problem and what ram i should be havingFirst of all, what are the rest of the specs for the system you put together?

The mobo you have supports Dual-channel DDR2 800/667/533Mhz RAM.

What to do in the meantime is take everything out except GFX, CPU & RAM (If you have more than one stick of RAM, try it with one stick at a time)also have intel 3ghz duo and 2 1tb western digital internal hard drives 1 200gb and ati all in WONDER graphics card 600w power supply i tried switching the rams still doesnt workSounds like you need to re-read your motherboard book.
With a new build, it is easy to overlook something.

Do the fans spin?
Is the power supply switch turned on?
Which type of RAM are you using?

Have you tested the PSU with a known working OSU (of greater or equal wattage) or another known working RAM stick that is compatible with your board?thanks alot everyone i got it up and running im pretty sure one of the rams were defective im so happy THANKS GUYSDownload and run Memtest86. You'll need to make a CD

Boot from the CD and TEST one RAM module at a time for at least 2 HOURS. (Longer is better up to 7 passes.) If both modules pass individually (have no errors), test the system with both modules in for at least 4 hours. ANY error means defective RAM.

Best of luck.
