PC ISSUES

[dominator200]

I a custom built pc spec are as follows:

-Thermaltake case with four fans not including gpu and cpu fans
-Assus motherboard i think m4ne not sure though
-Gainward 260 gtx golden sample 856mb gpu
-Kingston 3gb ram 800mhz
-AMD 7850+ dual core cpu
-On board sound card

My issue is that the computer just shuts down not that often but in the last two weeks it has done it twice I have installed nvidia system monitor and the temps of everything isnt that high my gpu goes upto about 58 degress when playing cod mw2 mcp about 65 and cpu about 45 so I was thinking it was overheating, but when I feel my case it feels margionally warm but not hot. So I was wondering I there is a way that I can run some diagnostic on the pc to see if I can find out what is happening, there is no blue screen or anything like that it just turns off not shut down sequence just power off everything I have is less than a year old any help would be appreciated thanks.

I'm gonna say, as a last resort, you take a look at that 500watt power supply.

Personally I use CoreTemp for monitoring my CPU temp, but for a good overall temp program I would suggest HWmonitor.

Just to be sure, do a double tap with all of your drivers to make sure it's not that.

Make sure your BIOS Auto-Shutdown Temp is disabled or turned over 80c.

I'd say its either Windows or your Power Supply Unit (PSU) as PSU's and HDD's are always the first to fail.

Forget about the calculator, 500 W *should* be enough. Even if it isn't, the best way to find out what's wrong is to plug another power supply in your old one's place.
