Ok from the video it looks like that once the motherboard has finished its testing phase that you are hitting the key to enter the bios, as it dos'nt seem to be failing the test as such.
Have you tried to leave it testing, then let it re-boot, and not entering the bios at that stage, by that i mean just let it boot normally?
The psu is fine, don't worry about that its a quality make.
Ok so where it says 205 in ur vid, u know thats the FSB and needs changing so thats good. Also u know what to look at to make sure the memory is at 800, changing the memory multi so the memory shows as close to 800 as possible in the 2nd column, it will always show 800 in the first one so ignore that.
And ofcourse you know where to change the vcore if its needed.
One thing i spoted in the vid is i think the memory voltage which shows normal 1.8v, but its set to 2.0v, i would put that back to 1.8v, unless you hav'nt touched that previously, if you hav'nt touched it then leave it.
Ok so now make sure all the settings i said in the previous posts are still there, save the bios, let the motherboard do the testing phase, this time do not touch the keyboard at all, no matter how long you think its taking to test.
If after 5 mins nothing is happening, then turn the comp off with the power button. And restart and enter bios and reset to normal.
Now i do have a feeling that you are not letting it fully do the test, and that you enter the bios far to early after it reboots, so give it time, and try not to enter the bios after the testing, booting phase, and lets see if it will load windows.
Also another note, best to be paitent waiting for replies, as at times the forum can be slow, other times its like a mad house lol.
If that still fails to load windows, then re-enter the bios from a restart, and set the bios to load default settings, and then we will just have to wait for someone with more experience of your motherboard.
