Weird computer freezes on new system :(

[Chissler]

Hello guys! I am sorry to bother you guys with yet another " Please help me, my computer is imploding into itself " question, but I am hoping you will be able to help me out a bit.

I just bought myself a new gaming rig. The specifications is as follows:

2 * Asus Geforce 8800 GT 512
Q6600 CPU
ASUS P5NE-SLI
Corsair TWIN2X 6400 DDR2, 4096MB CL5
Tagan Easycon 430W ( 20 amp on the 12v rails ) http://www.tagan.com/pages/products/easyconS/e_tg430_u15.html

The rig is giving me decent performance, but it will hang/freeze at different times. It can vary, but it occurs more often if I run games or application that drains the system a bit ( Gears of War especially )

For example: I am playing Bioshock, and have been doing so for about 1 hour. All off a sudden the screen freezes, the sounds stutters but then starts playing again, but I cant do anything. CTRL-ALT-DEL wont respond and the music/sounds will stutter from time to time.

I have been checking the system for any errors and this is what I found out that might have been causing these errors:

1. The ram timing was off ( 5-5-5-31 instead of 5-5-5-18 ) * Corrected
2. The ram was running in Single Channel instead of Dual- Channel * Corrected
3. The Bios settings for SLI Broadcast Aperture was turned off * Corrected (set on auto)
4. The Spread spectrum settings for PCI-Express was set to Scale Down ( I turned this off )

Do you guys think that those things might have been causing my computer to freeze ? Or could it be my
PSU ? I have read somewhere that a PSU with to little power might cause random freezes.

It is really weird considering that I had a demo of 3dmark06 rolling on my computer for 6 hours in a row, and it didnt freeze then.

But playing Bioshock for 1 hour might freeze it, or so may Gears of War, Crysis etc might cause it to crash

I am hoping for some tips/trics/advice from you computer wizards out there. Hope you can help me.

Sincerely yours

A single 12v rail PSU with 36 to 40 amps on it most likely will fix your problem. Or you could try to balance your cables over the 2 12v rails to use both of them more effectively.

Something else that can help.

Also having the most recent drivers for your video cards and patches for your games might help too.

For myself, I opt for tier 1 single 12v rail PSU's

Apparently the guy is trying to be funny people...ignore.

I am ? I really belive it is that much. I am not sure though. I think I read on the datasheet that it delivers that much amperage. Not that I have that much of a clue when it comes to PSU's.

Btw, thanks for all the responses guys. I am gonna try and remove 1 of the 8800's and see if the system stabilises while I wait for a new PSU.

Thanks for the help
