hi everyone,

what would be the cause for my pc to suddenly power off randomly without notice?

600watt pwr supply asus 680i nvidia chipset core2duo 3.0ghz geforce8800gt corsair xms 2gig ram

it happens maybe once every few days but its really bugging me, it should either always run, or not start up at all. btw its not a heat issue it just did it a half hour after booting

any help is greatly appreciated

Either it is a virus or heatingproblems. If you built your comp urself make sure the cpufan is attached properly (lol at me).

im monitoring my cpu and gpu they're staying cool, + i always keep virus protection up to date. how often do brand new power supplies crap out?

Did you build your new computer by yourself? If so, check that everything is attached correctly, and that the fan is strapped on tight.

Make sure that all power connections and fan connections are properly seated. And if everything is fine, you could have a case of bad voltages on the power connections.

However, what exactly happens when the computer shuts down? Does the power just shut off or does a message come up?

Wow, thats a nice heater you got there, I bet that system produces more heat then a gas fire place! In other words, I'd put 80% of confidence into it being heating issues, mobo's are all programmed to restart or poweroff when a certain temp is reached, that temp for me is 60C, so as soon as my GPU hits 60C there goes my computer (My GPU idles at 51C, 8800GT)

What are they btw? [quote=Sgt. D. Pilla;4225952]Wow, thats a nice heater you got there, I bet that system produces more heat then a gas fire place!

He may not have that set up. None of the computers I have ever worked with have limits on temperatures unless I set them myself; however, anything can happen.

Also, to solve this, what are your idle and load temperatures?
