1. Get CDBurnerXP, which despite the name works fine with Vista and 7, as well as burning DVD's and Blu-rays. It's also free. It might want to install various toolbars and whatnot though, just deselect that stuff.

2. Run the program, choose "data disc".

3. In the "Disc" menu, choose "Boot options"

4. Check the box "make disc bootable", then click the "..." button and find your img file, click "OK".

5. Drag and drop the files you need to flash the BIOS at the area with the "drag and drop" instructions.

6. Click Burn, choose finalize disc. Insert a CD-R disc into your burner if you haven't already.

Now you should have a bootable CD ready to go.

If the BIOS update is fixing issues with memory, it might be better to do the flashing using the old working stick or at least test the new sticks with memtest86+ to be sure it is safe to flash the BIOS with them.

It seems that some of the new motherboards no longer have internal PC speakers and most cases lack the external one, so all those error beep codes are not heard unless they are passed through the integrated sound chip and your speakers are on with sufficient volume.

In the end, how did you populate your ram slots ? : I understand Blue + Blue caused trouble so did you opt for, White + white or White + blue ? In the latter case, do you get dual channel ( that would mean that the memory slots have been wrongly assembled as you're supposed to use blue/blue or white/white ) or single channel ?

When the machine was first assembled, because I wanted to stick my old Hard Drive inside it together with the new, it became a bit cluttered inside the tower. Later, when I bought a new (massive sized) video board, it became even more cluttered.

So, I have 4 slots arranged in a blue-white-space-blue-white composition. The first two are free, but the other two are under the HDs and all those tape-like information cables (forgot the name).

Anyway, the guy who assembled my machine used those first two slots (Blue-White). So when the new sticks arrived I figured blue-blue would work better somehow (I wasn't exactly aware of the dual/single channel thing, but was sure something was supposed to work better). While I had stuck it to the second blue socket, some cables were constantly touching it. I'm not sure it meant anything, but I supposed that it could affect it in some way (even if it was just pressuring the stick), since I was getting memory failures.

So I changed it back to the original configuration used by the guy who assembled it first. I'm yet to check that dual/single channel thing, if it's working one way or another. I'll post here when I find out latter today.
