|I put together an Abit KV7 with an AMD 2900+ for my wife and we have siilar issues with her PC. There is a Abit Windows monitoring tool you can install to let you view current fan speeds and temp and set the alarm thresholds. I have the alarm there set to about 50C myself, maybe you are seeing a default at 42C.|
We have had a major problem with the system just powering off completely with the High-Low alarm you mentioned. I enabled the temp alarm and it sounds about the same as this but it goes off before the system will power down giving me a heads up.
Now on this PC we get this power off about any time we open more than two applications. Sometimes this happens at night or when the computer is idle and no one is using it but a couple of programs are open (mail, browser)
Since you mentioned playing games with would really drive up the CPU utilization on a system I suspect this is why you get the alarm. This would also be expected during a system boot since lots of processing and disk activity is going on.
Anyway I wanted to share this with you, seems like a problem with Abit possibly. This gets on my nerves though. I have a $20 cpu fan on there and I was thinking of replacing it to see what happens or adding another case fan. I have an AMD 3200+ on my PC using a Shuttle board and I never have problems like this.
I got this Abit as a package deal as I usually dont spring for that high end stuff but I can not say I will ever go that route again since I never see problems like this with other boards.
