(SOLVED) Huge problem, help needed.

[DivineRage002]

First, here are my computer specifications.


Motherboard: ASUS P5N32-E SLI Nforce 680I SLI LGA775 Conroe ATX DDR2 2PCI-E16 PCI-E1 2PCI SATA2 RAID Motherboard

CPU: Intel Core 2 Quad Q6600 Quad Core Processor LGA775 Kentsfield 2.40GHZ 1066FSB 8MB Retail Box

Graphics card: EVGA 8800 GTX

Hard drive: Seagate Barracuda 7200.10 500GB SATA2 3GB/S 7200RPM 16MB Cache NCQ Hard Drive

Power Supply: OCZ GameXStream 700W ATX12V 24PIN SLI Ready Active PFC ATX Power Supply 120MM Fan Black

Memory: Corsair XMS2 TWIN2X2048-6400C4 2GB 2X1GB PC6400 DDR2-800 CL 4-4-4-12 240PIN Dual Channel Memory Kit

OS: Windows Vista Home Premium



The problem I'm having, is that whenever I try to run something that needs a bit of power, the computer just shuts down, without any warning.

This happened in the following situations:

Playing a videogame
Doing a scan with SpyBot
Running 3DMark05
Trying to get a rating for my computer with Vista's rate-your-computer-thing


Another interesting thing I noticed, is that when it does shut down, and I start it up again right away, it will shut down again when loading Windows, while if I wait a bit (one minutes or so), it will be fine.



Edit: I just tried to run Starcraft, and it works, however the colors are messed up.

Edit2: In-game is fine, its only the menus.

Welcome to hope.com !!
(first off)  most impressive !!  Nice ~

1.  Vista  <  probably/ might be  having some hardware issues.
2. driver issue ?  ( look for further comments here on this, I am not too knowledgeable on particulars.... 
3.  Are you over clocking this board ? there are some major problems occurring with the 680i  .... the 680i board with the quad core chips are failing..mfg -problem.....
I know EVG is giving free replacements not sure on Asus 
4. Heat ?  do you have more than the 1#   120 mm  fan on the psu, ok >how many other fans are in the case & do you have the stock heatsink/fan on the cpu  or an upgrade  ?  that card's heat is intense , are you getting good air flow in your case, monitored the temps?

Sounds like a heat problem.
Check your temperatures, as honvetops said.
P.S. Nice computer.

Alright, I unplugged the Zalman 9700 heatsink and re-plugged it in, seems to work fine now.

Sometimes we are just that good.

Sounds like it was just a loose connection, leading to a heat problem.
Glad you got it sorted and thanks for posting back.
