After installing everything, I booted the computer. It turned on, but it wouldn't show anything on the screen.

I reset it, then it would post, but it would freeze at the graphic screen that shows the type of motherboard it has.

I reset it again, and it would boot from CD, where I installed Windows, but it froze during loadup.

I reset again and it installed windows without freezing.

I then tried to install the motherboard drivers, but it froze during installation.

I tried again and it installed it.

After resetting, the computer would reset during boot, and it would not get to Windows.

I reset it again, and it got to Windows, but then it immediately blue screened and reset.

The RAM I am using is this one:

Yes, you change the RAM/FSB ratio in the BIOS. What speed is the RAM currently showing up as in the BIOS? You need to manually set that RAM to DDR2 1066 speed with 5-5-5-15 timings at 2.1v according to the manufacturers specs. If you have everything on auto in the BIOS, the RAM is most likely running under clocked. The motherboard owners manual should tell you how to adjust the RAM speed/timings/voltage. You may have to press "Ctrl + F1" when you get into the BIOS to unlock some of the settings.
