EPoX 9NPA Ultra Board Problem

After my last system failed, I purchased the following components:

1. Epox 9NPA-Ultra Mobo
2. AMD Athlon64 3000+ Retail (Venice core)
3. 1 GB Corsair DDR400 Dual Channel RAM
4. Asus Radeon EAX300SE Video Card
5. Seasonic S12-430 PSU

I re-used from my old system: 60GB and 200GB IDE HDDs, CD RW, DVD RW and floppy drives, as well as a Hauppauge PVR-150. When I first hooked it all together, it wouldn't post. I disconnected all the peripherals except the Hauppauge and video cards and it still wouldn't post. When I took out the Hauppauge card, it posted but stops at the following error:

CMOS checksum error - Defaults Loaded
Warning! Now system is in Safe Mode
Please re-setting CPU frequency in the CMOS setup

At that point, the machine stops and I cannot hit either F1 or Del (to get into the CMOS or proceed). The error code displayed on the mainboard is 7F.

I Cleared the CMOS several times using the jumper on the mainboard and it didn't solve the problem.

So, can anybody recommend a solution on what I need to do to get this working properly??

Thx!

What does the manual say for the code 7F?

Right now, it looks like it's heading in thre RMA direction. Thanks to everyone for their input.

oh good point!
