I have been having trouble with my dual mp system using the Tyan s2462 MB.
The system won't restart after it gets warm. I have to unplug the system for 5 minutes to boot again. I have had the cpu in the shop and he replaced the MB and then a new PS. It worked ok for 48hrs then started to give the same behavior.
It crashes... blue screen... after a day or two if left on.
System worked fine for the first two years.
I noticed the 12 volt system reporting starts at 6 volts and goes up to 14.3-14.5 voltsover 15 mins after starting.
It will restart normally until it reaches about 13 volts.
Any suggestions? Another bad board?
