I'm having trouble with my first build. All the hardware is installed inside my case. (http://www.newegg.com/Product/Produc...82E16811146029) Thing is, when I boot up, it runs for a minute, and then shuts off. I checked all the cables, wires, balhalhbabla.. everything seems to be okay. I tried putting in the Vista disc [64 bit] in my drive, in order to boot off of it, and it seemed fine at first. 'said the files were being downloaded. Shortly after, the computer shut off again.

I'm using an EVGA nForce 780i mobo, and a 1000w Cooler Master PSU (http://www.newegg.com/Product/Produc...ler+mas ter)

If you have any idea what MIGHT be going on, please let me know. Sucks to be in BS already during my first build. Although I expected it. If you need to know about any more hardware, let me know.
 
The first thing to note there is that the system did start ruling out miswiring anything or simply forgetting to plug something in. The possibility of a bad component like defective capacitor on the board itself is there. On a new build here the board simply quit after only 3 days of use and was exchanged for a working replacement.
 
The 12v cpu being left unplugged would like having a loose contact inside the plug itself and prevent even seeing a system go through the post tests. The description there sounds more like a board or perhaps supply problem since the largest pull for power is gnerally seen at post.
 
Most boards if you leave it unpluged it will boot just fine, but with alittle draw on the CPU will make it restart, seen it many times.
 
Sounds to me like a heat problem. Did you put the thermal paste between your CPU and the heatsink fan? And are you certain the CPU heatsink is mounted correctly?
 
Does it take that little time to let heat become an issue.. enough to turn off the entire system?

and.. I don't have any thermal paste.
 
Oh yeah, it will only take seconds for your cpu to overheat and shut down your system.

When you first turn on your system, can you get into your bios? If so see what your cpu temps are.

If you installed a brand new heatsink fan then chances are there was some thermal paste already on the bottom of the heatsink.

Did you see any silver/gray paste on the bottom of the heatsink?

If not, then that's your problem. You need to stop booting this system immediately and remove the heatsink and buy some thermal paste. The best paste around is the Artic Silver.

If you did see the paste, then are you sure you seated the fan/heatsink correctly?

Continuing to run this system without some thermal paste between your CPU and the Heatsink will cause serious damage.
 
Are you sure the heatsink was seated properly?

Usually when you take off your cpu fan, you need to reapply some new paste, but since have not really had this system running, you might be ok. What happens is that the old paste over time will "burn in" and if you remove the fan, you need to completely clean off the old paste and apply some new. But since you don't have any, you should be ok for now.

Were you able to get into your bios and check your temps?

Did you see the cpu fan spinning when you turned on your system?
 
The first thing that would kick in when a cpu gets hot too fast would be the overheat protection circuits very much standard on boards at this time. The initial breakin time for the newly applied thermal paste will see warm temps along with not having enough good air flow in a case.

When the board temps are up so are those for the cpu. I saw that when upgrading an old Socket A case where the two 80mm fans simply weren't enough then seeing the board at 48C idle. Once moved into a new case with a large front intake and 120 rear fan the board temp dropped sharply down to 31C with the cpu dropping from 46C down to 33C almost immediately.
 
Go back into your bios and watch the temps, see what they are when your system shuts down by it's self..

49c is a bit high for a non loaded system, especially right after booting. This looks like it is an over heating problem, but we need to know what your temp is getting up to.
 
Another thing that come into play is the type of thermal paste or compound used. While Artic Silver 5 takes a few days at first to see thermal conduction take hold other pastes leave quite a bit to be desired as the expression would go. During the initial breakin period the temps will run a little high due to the type of paste.

While 49C seen right after the first startup of the day would be a scary situation you have been running the system seeing it warm up much faster due to this. The board, cpu, and everything else would still be warm even after sitting for a period of time. For seeing that at the first startup you may be seeing a cpu problem if not simply not seeing the hsf go on correctly.
