Power failure

[tany]

Hi,
I have a PC with GiGABYTE GA-945GM-S2 Motherboard.
From time to to the computer suffers from power failure and i have to turn it on again. When it happened last time, i went into the CMOS and Enabled the "System Fan Fail Warning". Whe the computer restarted, i got an alarm noise so i disabled this feature. I figure that i have some problems with the System fan, though, i would like to ask, if this can cause the computer to turn off. Is this design intent ? Namley, if the motehrborad suspect some hardware failure, it shuts down, to avoid disaster ? I went to GIGABYTE web site but I wasnt able to find any clue for this issue.
Need you advice.
Regards,
Tany

Most likely is overheating.
Is your room temp high? If so you may need some extra heating.
Go to www.majorgeeks.com and download and run everest - this will give you some temps of your CPU and board; also the current from the PSU.
Let us know what you find?

Can it cause the computer to shutdown ?
I downloaded EVERTEST but it has problems recognizing my hardware.
Can you recommend on alternatives ?
By the way, i set a CPU temprature thrshold to 60 Celcious and after some time the computer started alarming. So i guess you right, yet i see that all fans are working proprely.
What can be done about that ? Should i replace the power supply ?
