Asus A7N8X Deluxe problem!!!!!!!!!!!!

I recently replaced my stock CPU cooler on my Athlon XP 2400+. I purchased a Thermaltake Silent Boost, and the installation went fine. I added Artic Silver 5 paste on the CPU. I started the computer and it went into Windows fine. Then I noticed that the FSB reverted back to 100, so I entered the BIOS and changed it to 133. Because the CPU is 133*15 = 2000 MHz. I saved the changes and restarted. Now it won't post, and the Asus reporter gives me a MEMORY ERROR. I have reset the CMOS, changed the sequence of the memory, boot with no sticks, just one stick or the other, try different slots, nothing. I have also taken out and put the CPU back in the socket hoping that would reset something. I can't understand why the computer says there is a memory error. I have been using this memory for the past 1 1/2 years. Please help?

Ummm. Hello, the computer will not POST. It gives me a MEMORY ERROR, therefore it fails the POST test, and the computer just sits there. Little update: I tried a different video card, different CPU, and a new battery and none of those things helped the situation. I guess the board is done. Somehow the BIOS must have been corrupted. I will have to RMA it back to Asus. I have run out of ideas. The only thing I could try, would be different memory, and I do not have any other DDR memory laying around.

Well, I went into the BIOS and made my changes, then I clicked Exit and Save Changes. I clicked Y for Yes, and then once you hit Y and Enter, the computer automatically restarts. Thats when the problem happened. Once it restarted, it said Memory Error, and the computer fails POST test. I believe the BIOS got corrupted, even though I didn't touch the power button. I have an RMA with Asus.

Looks like you should at least TRY some different memory. Will it run at the 100 MHz FSB?
