I have been trying to get my new system up and running all weekend to no avail The specs are as follows:
AMD Athlon 1200 AXIA
Asus A7A266 mobo
256 mb Crucial PC2400 DDR
ASUS Geforce 3 Deluxe
IBM Deskstar 75GXP
Enermax 350 watt power source
Ok, once I got the components installed and hit the power button, the system fans spun for like 1 second then died. Originally, I thought it may be a power source issue so I went out and bought an AMD approved Enermax 350 watt ps. Same problem... Now after reviewing many threads relating to the A7A266, I believe I have one hope left. An earlier post states that a motherboard may short out if there are spacers located under the motherboard in which no screwholes exist. Since I am using my original case, I believe I may have some spacers from my previous mobo which do not conform to the A7A266 installation holes. Does this sound like it may be the problem? Other than this I have no explanation as I believe I have tried everything:
Removed all components except for mobo, cpu & ram
Reset the bios
Reseated cpu, ram and heatsink/fan
Any input is greatly appreciated! By the way, would the extra spacers damage the mobo, cpu or ram or do they short out the mobo with no damage - if this is possible?
check the m/b book and CPU fan. My Asus K7V 133 says 350 mA (~4.2 watts)is the max for using on board power connections. My Delta fan said 0.48 amps (~5.75 watts0 so I bought an adapter to connect the CPU fan directly to the P/S.
IT is very common for novices, and occasionally even experienced asemblers, to replace a board and miss one of those misplaced spacers. But the shorted circuite most often is low voltage and does not usually damage the board, instead simply preventing startup.
