p5n-e sli normal beep freeze at initial screen

[kbouter]

All of a sudden, the computer will give the normal beep then freeze at the initial BIOS screen.
I cannot get into the BIOS.

I have removed all RAM, powered on with the appropriate beeps.
Put each memory stick in separately into each slot. Problem the same.
Used eraser on memory, no luck

Took it apart & put it back together, still the same.
Temps are normal

I first noticed that the programs were getting non-responsive.
Went to restart & not able to even get into BIOS.

Removed all externals, same issue.

I had replacement memory sent by Crucial about 3 months ago, 1 was bad.
They replaced all four with this newer type that used lower voltage.

Has been working perfectly until today
Will try a PCI video card to see if that helps.
Any suggestions are welcomed.

Thanx

First thing to try is clearing the CMOS.

I cleared the CMOS and now I do not even see the BIOS post screen & the delete key does not take me into the BIOS.
I still get the initial correct beep.
I removed the fan & redid all the thermal paste as per instructions as well.
I tried another stick of memory.
Still no luck with it.

Ok, Here we go

Previously, I tried a USB keyboard to replace the remote battery operated keyboard.
That did not work either.
I noticed that the battery op kybrd did not light up on boot.
I got a hardwire ps2 kybrd & bingo, it worked.
Replaced the batteries in the kybrd & running fine.

It' always the stupid stuff that gets U.

I have set the BIOS back up & it runs puuuurfectly.

I always appreciate the help here and hope that somebody else can learn from such a silly mistake.

no matter how many years of practice on puters, there is always something to be learned.

Thanx again

I turns out that this was not the problem.

After letting everything sit over night & restarting, same issue.

I get the normal beep but nothing else happens.

I used the computer all day yesterday, restarting, shutting down with zero problems.

This am, first thing, will not boot past the screen saying main processor:
Intel(R) Core (TM)2 Quad CPU 2.40GHZ
