I have a computer problem, can someone help?

[vladittude0583]

I recently had a custom-built PC made at CompUSA about 1.5 weeks ago with these features:

Antec 1,000 Watt Power Supply Unit
nVidia nForce 680i SLi Motherboard
(x2) BFG 8800GT OC 512MB Graphics Cards in SLi Mode
4GB Corsair PC-6400 DDR2 800MHz System Memory

When I brought home the PC, everything worked fine except when I started to install all of my Norton Internet Security 2008 and some other software. Therefore, I proceeded on reinstalling my OS. After reinstalling my OS and installing all of the software again, everything was back to normal except for one thing. An screen pops-up saying that I do not have adequate power for my video cards, therefore, it forces my video cards to go to a lower performance to match the "inadequate" power supply I have installed so that the graphics cards won't crash/freeze the OS, etc.

My question is, how is this possible when everything is the same before I reinstalled the OS? I did not install any new DVD drives, HDDs, etc? Do computer "builders" manipulate the power supply or something? I did not remove any cables whatsoever because I do not even know where to begin. How could the power supply be insufficient after when it was perfectly fine before?

Can someone shed light on this?

Thanks.

make sure all ur drivers are up to date. and open the case to make sure they did connect all the wiring properly. I dont know if those cars need a power plugged into them, but maybe the dudes at compusa didnt do it right and got the message to go away before you got it home.

Is it possible that it still is connected properly because I mean, I would not be able to configure it in SLi mode if it wasn't right? Do you think that the 1,000 Watt Power Supply is not enough? I find this conclusion hard to believe.

check and make sure the power cables are plugged into the video cards inside of the computer.

if you want, u can take a picture of the inside of the computer if u arent sure what to look for and we can help you further from there.

i have a very similar setup with 750 watt and its plenty.

in fact i belive my setup takes more than urs as i run 4 raptor drives in raid along with 11 fans *cus im stupid like that* with oc'd cpu and 8800 gtx, i got the stupid platinum edition sound cards etc.

u should def be fine on the p/s
