I have a nearly year old Biostar 6100-939 board with a AMD64 4000 cpu. Things were going fine til this weekend when it failed to startup - I don't even get to a post screen.
When plugged in, the green "power on light" on my case is lit and two of the four motherboard LEDs are lit (numbers 3 and 4 as read from left to right).
According to the 6100 manual, if LEDs one and two are out, then it is a "CPU / Chipset Error."
LED 3 being on shows that "This LED indicates the voltage of memory is activated normally."
LED 4 on shows that "This LED indicates the system is ready for Power-on."
The other thing i have noticed is that if I press the on-board reset button, the case fan and the graphics card fan both spin for about a second and then stop. The CPU fan does not spin.
Does this suggest a bad CPU over a bad motherboard?
So far, all I've done is take things apart and put them back together, but still I get the same error/situation.
While I did build this computer, I am finding that it was easier to start from scratch than to figure out what isn't working now (especially with no replacement parts on hand).
The only other thing I can mention is that between the last time the computer was working and now, I had to throw the circuit breaker for that part of the house several times to fix a broken outlet. The computer was off at the time and is downstream of a surge protector - everything else on the surge protector is working fine. Hopefully this part is just a strange coincidence.
Pardon my ignorance, but would a dead power supply still give enough power to light the LEDs and spin the fans, albeit for about one second?
I was reading newegg reviews of the power supply that came with the case (an Antec Sonata II) and lots of people have said their power supply died in the 8-12 month range. Exactly where I am right now ...
