Blank screen after BIOs

[KoolAidMan]

I recently bought a new motherboard, and when I put it in my computer went to the post screen like normal. After setting it to 'Fail-safe defaults' it begins to restart, but the screen is blank. I can hear everything booting up, and the minitors cable disconect message doesn't come up, but I don't get any video. I have tried resetting CMOS, which has got it to work upto BIO's again, and as soon as I set anything up it does the same thing, twice now.
Would this be something setup wrong in BIOS or would this be a hardware problem do you think? Also, it is an EPoX 8RDA3+ PRO motherboard, which I just bought to replace a different EPoX board. I have tried it with nothing but the CPU Video card and ram installed and it does the same thing.

Thanks in advance for any help.

Do you hear Windows starting?

Does it go blank when the windows loading screen would come up, or when it's still posting (ie. device check, boot check).

Since the mobo is the only device that's new, it seems the likely culprit. I would try adjusting vga-related settings in the bios (disable palette snoop and vga bios cachable; play around with assign irq to vga and other settings). This might be some help, but I would put more faith in a BIOS update.

Just to be sure, you can check your monitor plug to make sure no pins got broken off or bent during the mobo install.

Is the software (operating system) on the hard drive compatible with this new motherboard ?

It doesn't even come on at all. As soon as I hit the power the screen is just blank, as well as keyboard and mouse being off. The few times I have gotten it to show up all three of these come on, so I think it's a motherboard problem in general. When I do get it to come up it the boot screen says "CMOS checksum error - Defaults Loaded", and the board's LED usually has an F2 error. I can't find anywhere that says what this error is, and the manual that came with the board says to go to Appendix D-5, which doesn't even exist. Then it lets me in BIOS, where it either freezes while I'm in it (which I think is something totally different, this is why I got the new board to begin with) or it lets me get through and it'll do the exacty same thing right after. Every time I manage to get back to BIOS it's reset. It does this exact same thing whether I have IDE connected, extra ram in or anything. Unless someone can give me an idea, should I just RMA with newegg?

BTW, its an EPoX 8RDA3+ PRO board,

Did you try some different ram in the system? It sounds like it doesn't like those modules, that's what usually causes the "checksum error". That means what's reported is different from what it's finding at POST.

You using onboard video? If so, try an AGP or a PCI video card.

I'm using Radeon 9600XT 128MB DDR AGP 4X/8X Video Card.

I tried to switch the ram but I wasnt able to get the screen to ever come up to see if it changed the error.

Can you check that the CLRCMOS jumper (near the battery) is set to 1-2, and not 2-3
