Gaming Computer shuts off at 38c? Help!

[x BattleHeart x]

I have lots of mods that very rarely crash to the desktop, but when i play Fallout 3 and my computer heats up to 38 celsius on the CPU and SYS categories it reboots. I have a custom setup I bought off iBuyPower. Specs are Core i7 920 2.67Ghz not overclocked, running on Turbo mode. 3GB of Memory, and the heatsink and fans that came with the case. I heard that a decent temp of a computer while playing games is low 40's yet mine can't even get there before it shuts down and reboots. While I'm not playing games it runs at about 30 CPU 28 HDD 30 SYS. I have no idea if i'm doing anything wrong or I need a better fan or what. Someone help please.

does this happen on all games?

Is there some safety shut down type thing in the bios that is set incorrectly? Might be worth having a nose around in there.

Fallout is the only game i've played on here but i'am about to try Oblivion right now. jim_uk, that's what I figured but I cant find anything in the BIOS or on my Control Panel to prove that. I checked out the fan and it runs fine, but shouldn't it run to something like 80 celsius to begin overheating? It's starting to get really annoying and it always shuts off 37 to 38 degrees celsius.

Definately sounds like there is a safety kill thats set incorrectly, too low. My CPU at 120 degrees F, thats just with me playing music and surfing the web lol. But Im also running am AMD 6400 BALCK edition dual core, each at 3.22 ghz with 4 gig DDR2 and two 9600 in SLI, a big 750 watt power supply on top of that.

What monitering programs are you using to observe youre temps? Im using PC Probe from ASUS.

Just a hunch here, but have you recently checked your power supply unit?

I'm just going into the BIOS and reading the temps it says in there...I have a 700w PSU and I turn all other programs off when I play. It heats up slowly unless I'am in a heated battle like at the Capitol Building then it starts raising pretty quick. I dont really know where the "safety kill" thing is, if there is such a thing...where would I look? Nexus Set, how do I go about checking my PSU? And Harabec Weathers, I noticed Semper Fi on your sig, I'am a Marine stationed in NC right now...SEMPER FI! Haha,Thanks in advance for the help guys.

You should see something like this in your BIOS settings:

just to put your mind at ease, from what i read while researching my i7, the bracket 30-70* is more then ok, 32*c is a more then safe so i think the others are right it must be a saftey mech.

 

No disrepect to members of Nexus, but these guys over at tech-forums.net live and breathe this kinda stuff, your prob best off asking there, i use it for al my comping probs and i normally get the correct answer within an hour.

Well, guys I've came up with something interesting...I don't know if any of you already knew this or it may be that I just neglected to mention it, because I thought it was irrelevant, but I launch Fallout 3 with the fmod. By doing that, I don't have to have my Fallout disc in the drive. I just was thinking that just maybe since the disc wasnt in there my computer was taking the full load or something and I figured I'd put the disc in and launch it the proper way without fmod. Well guess what, My computer still heats up like normal comps do but doesnt shut down anymore, so I'm thinking that must be the reason. If anything else comes up I'll comment but its seems to be working fine now. Anyways, thanx guys for your time on this as I just bought this high end gaming pc and thought something was messed up, I appreciate your help.
