K7S5A comp wont post 1

[Kilroy1441]

Motherboard: K7S5A
Processor: Athlon XP 2700+
Video card: Radeon 7500
RAM: Kingston pc3300
PSU: Allied 300W
Hard Drive: Maxtor 7200rpm
CDRW: ASUS 52x/24x/52x

About two months ago i had a power surge with a different psu. i determined the motherboard and processor were fried. i replaced them under warranty. i can get the fans to spool up but nothing else happens, no lights, no beeps, nothing. i have a new psu but have also tried booting from another psu with the same results. i have swapped out the video card with a working geforce two, same result. i have swapped out the ram, same result. i have re-seated the processor, same result. i have tried different monitor, i have booted on pink foam. it is my opinion that i got a bad motherboard even though it is brand new. i would like to avoid getting another one if it isnt the mother board. is there any thing else i can try. any suggestions would be greatly appreciated

As I recall, the ECS K7S5A can't handle any Athlon chip over 2400+ because of the difference in bus speeds. The 2400+ and below run on a 266MHz bus, while the 2500+ and higher run on the newer and faster 333MHz bus.

You might want to check out ECS's L7S7A2, it is another cheap ECS board, but it supports the 333MHz bus. Here is a link:

AMD did put out the athlon 2600+ with a 266fsb, but I believe the 2700+ is only available with 333fsb.

Another thing to consider with your mobo, by chance I just came across this site searching for something else, might be helpful:

thanks a lot i had never heard about this issue. when i first built the comp. it had a 2400 plus but when it got fried i went ahead and upgraded it to a 2700 plus. this would explain why it worked when i first built it. thanks very much for your input.
