8800GT help, not receiving sufficient power

[MavSkipper]

So I've recently purchased a 8800GT(upgraded from a 7950GT) and I'm having this problem since

Everytime I restart my PC, a nVidia message pops up telling me that my card is not receiving enough power
I've re-checked many times all the connectors in my PC and it still the same, although there was one time that the message didn't show up and I could play games perfectly... but that was only one time until I restarted my PC
I don't know what's happening and I seriously need help on this one

here's my specs

C2D E6420
MSI P35 Platinum
4GB Geil Ram
Enermax Galaxy 850W
WinXP 64-bit
nVidia driver 169.02(also tried the beta driver and still the same)
Zotac 8800GT

if there's anything else I missed, let me know

There's an "8800GT problems" thread right below this one.

I'd suggest that perhaps you see if any other devices are connected to the same rail as the video card. Disconnect some other devices such as extra harddisks, optical drives, and so on ... and see if that clears it up. Just start with bare minimums.

pcgeek86, that's a thread about a completely different topic, in any case .

OP, you do have the 6-pin PCI-E connector plugged in, right? Also, if so, as pcgeek86 said, try unplugging devices that aren't essential to boot such as hard drives/optical/etc. and see if it shows the message then.

I had this same problem with my 6800gt with windows xp only,do you have any kind of molex 6pin adapter connected to the 8800gt? I think that was my problem with windows XP. Now when I installed vista I wasnt getting this message at all.

yea, I did all that... I even plugged the extra 6-pin modular cable and used it but it's still the same

I also had a copy of vista(legit mind you ) and installed it because googling earlier for problem, I came across a thread about the message not popping up... well it actually didn't pop up but once I started 3dmark06, it was running @ around 7-9 fps so I don't think it was resolved

right now, I just updated the BIOS on my MoBo(now vers. 1.5) and I will change the videocard in a moment(using the 7950 right now)

will post back how it goes
thanks for the suggestions


edit:
no luck.... still the same :/
