Really weird 6800GT problem...

[g2tegsown]

Ok here is the deal, my chipset fan died and I borrowed some from the computer shop I work at just to measure up the size to make sure it was just the standard layout (The fan is held by spring loaded plugs that go through the motherboard), and it was. However I removed my video card at this time to ease the job, anyway I put everything back together and my computer boots up fine to a message that says my video card isn't getting enough power. Now I have a 520W OCZ Psu and it has always worked fine, and now it happens at every boot. However one thing I did notice was that the driver now has my video cards ram clocked to 2GHz, and it should be 1GHz, when I try to clock it to the normal speed and I run the "test changes", it fails. When I run Need for Speed Carbon it runs like it usually would, maybe a hair faster than normal.

I read somewhere that some had a driver problem similar to the problem I am having, so I uninstalled all my NVIDIA drivers (Chipset Driver+Display), got the latest drivers, ran driver cleaner for all NVIDIA stuff, reinstalled, everything went fine except as soon as the video was finished it popped up with the under powered message again.

Any ideas?

Also I have reseated the video card several times, as well as the PCI-E power plug to the video card.

I hate it when stuff like this happens. you change something to fix a problem and all of a sudden another problem arises that has nothing to do with what you did.

Does the video card need to be plugged directly into the power supply? (I'm not familiar with how pci-express works, I know that it gets its own plug from the psu into the motherboard) Does an alarm go off in the video card if it's not plugged into the psu(assuming that it does plug in to it) Try using a different rail on the psu.

Maybe get some airduster and make sure no dust got inside of the pci-express slot in the mobo as well.

Just to check, check your voltages in the BIOS and see if they are reading ok.

Does a molex get plugged into the motherboard?
