Software: To Blow Pc's Power Supply

[Macstorm]

It's second time it happened to me:

1. Two years ago, I installed Intel Active Monitor application http://intel.com/design/motherbd/active.htm for my Intel D850MD mainboard. Within following days after, a persistent alarm in the application warned me on an increase of temperature coming from "System Temperaure"(cooling tab), happening only when running certain programs. Once, while away from PC, I found the machine 'dead'. No electric current, simply dead. Needless to say I stayed breathless. I went to tech service and 'fortunately' technician found the PC's Power Supply Box overheated and dead. I explained him problems started after installing IAA, but he was unable to find a reason of overheating. I bought a new power supply box, uninstalled IAA and all went back to normal.

2. Last week I decided give a try and install F-Secure antivirus 2005 (full uninstalled previous one before). After reboot, performed a system scan with it. While scanning, I heard a loud 'beep' sound coming from into PC case and it powered down on it's own. Went to tech service and, again, the PC's power supply box 'dead'. Same history

This is VERY strange to me.

I know a new hardware installed may conduce to a general system electric failure but I have no idea on why a software???

PLEASE, any advice, thoughts, ideas or whatever to help me to understand this system behavior.

Thanks

As far as the software, it is probably just a freak of nature that it just so happened when you installed that software, it was probably going to happen anyway. Do you have a surge suppressor where your computer is plugged in. Maybe you are having power surges. Do you have a UPS. Maybe getting one of those may help.

Yeah my guess is power surges...buy yourself a UPS

I have a electric voltage stabilizer and surge supressor between pc and wall outlet. AFAIK, UPS only helps to keep PC powered on in case of electric failure. What I'm thinking of is, say, if CPU is runnning to the maximum, why would this conduce to blow PC's power supply box...

An UPS can also be used to stabilize voltage

It could be that you used a too small power supply but still, CPU´s are not taking up more then 85Watts . If you buy a new one now then go for an Antec. What brand did you use before?

ps. Did you ground your PC well?

Thanks Folks,

What I don't understand is why PC's Power Supply Box 'overheating' happens only when I'm running certain programs (like IAM, original post), but this supposed 'electric overload' simply vanish after uninstall these programs. It's software vs. hardware. I find no sense here
