No POST screen on startup

[Buzby]

Hi,

 

I'm having a similar problem to lots of other people it seems! The 4 diagnostic LEDs stay lit constantly upon startup and nothing appears on the screen.

 

I've been testing things all day from information found on this and other forums to no avail. I've tried moving the DIMMs all around, using just one in all the different slots. I've disconnected everything so its just the GPU, CPU and RAM connected. I've tried the CMOS reset that was suggested (including a long 10hour one!) but to no avail.

 

I think the problem is that my board does not support E4 Stepping (found in my 4000+) without updating the bios to the 3/10 version. So, the motherboard cannot detect the CPU on startup since it isnt supported using the bios that the board shipped with.

 

The problem is how do I update the bios on the board when I cant even get it to boot to the BIOS? I dont have any other CPUs I could use to flash the bios to a later version.

I had a similar problem, but even with an old 3000+ Venice the board did not do anything new, so I figured that it was not a BIOS issue. The board is being RMA'ed

Does anybody know whether I should be able to get to the BIOS with my Athlon64 4000+ using the factory shipped BIOS?

 

My board is revision R.AD0 if that helps.

If that is the case I may not need to RMA the one I just recieved. I opened the box and it powers up just fine but the 4 led's never go out. I've tried 3 different power supplies and 2 processors, but they were both Venice CPU's so its hard to say if that made a difference.
