Comp shuts down after 5 sec...PSU or MB problem???
Posted on 2003-03-11
I'm running a 950MHz AMD Duron that I put together about 2 yrs ago. This past week however, my home was struck by two power outages while the comp was on. Even though I use a powerbar, I think this may have caused my current problem.
It happened a couple of days after the last power outage. I was on my comp playing NHL 2003 when it frooze for about 3 seconds before automatically turning off. I was unable to turn it on after that. A smell of burnt electronics followed which I determined to be my power supply blowing out. So I replaced my PSU from a 300W ATX to a 350W ATX.
Now, I can turn on the comp for about 5 seconds(or until it reaches the point where the BIOS starts up) before it automatically turns off. I have to reset the switch on the power supply before I can go through this 5 second trial again.
What is the problem here?...is it a faulty PSU or do I have to replace my MB?
Thanks for all your help!
