Bios Rom Check Sum Error

Ok, I just recently built my first system (about 3 months ago) It has been working great so far and I hadn't had any issues... until today.

Anyhow. I went out to see King Kong and when I came back I went up to my room and i see my computer sitting there in DOS with the Bios Rom Check Sum Error. I popped in my motherboard cd, and I used the Bios flash tool to fix it, it all goes normal. It tells me to reset my computer. I do so. The error comes up again, and I have to do the Bios Flash thing again.

Well basically this keeps happening. I have tried a few times to update the Bios, but I am not having any luck. I removed the battery, and changed the jumper so I could reset my CMOS, but that didn't help either.

The reason the update will not work is because after I download the update, I have to rename the .bin file to the correct name for my hardware. But its very strange, in the flash utility the file comes up with having 3 spaces before the .bin, so it looks like this:

"A8N5X .BIN"

rather than:

"A8N5X.BIN"

So it appears that the flash utility will not recognize this as the correct file, and therefore will not complete the update.

My ststem specs are as follows:

Asus A8N5X Motherboard (Socket 939)
AMD Athlon 64 3200+ CPU
1 gigabyte of Corsair Ram (2 x 512 sticks)
GeForce 6800GT 256GDDR
Western Digital 160 gig hard drive

So if I could get any assistance I would greatly appreciate it. Basically at the very least I wanna know if I should send back my mobo and get a new one, or if this problem is fixable.

Thanks in advance and if you need any more info I will gladly provide it so just ask!
 
Why do you have to rename the BIOS file? I don't see anything in the motherboard (or flash update) documentation that says you need to. Either just leave it with the 8 character name that you get when you download the file, or rename it to something like aaaA8N5X.BIN if you really want to rename it. I haven't personally worked with many Asus boards, but most motherboards I have dealt with want the BIOS .BIN file to have an 8 character name.
 
Well, my MotherBoard manual said to rename the bios update to A8N5X.BIN, so I was following the instructions. The Asus bios updates come with the name A8N5X(version number here).BIN. In my case the version number was 504. My manual says to remove that and install it that way, though I have tried it with the version number and it tells me that the file cannot be written in the Flash utility. I don't understand why.
 
A lot of times the bios will have an option in the bios for write protection, that you have to disable before it will allow you to flash, and I'm pretty sure my last Asus motherboard had that..
 
Yes, but unfortunately I cannot get into my bios. As soon as my computer turns on, displays my video card informations, the Bios Rom Checksum Error comes up. I can't seem to get past that no matter how hard I try...
