I got a strange problem with an unbranded geforce 6600, it was given to me as a gift and, no clue on what brand,
it looks unbranded
it has DDR2 memmory 256mb
cleaned and replaced thermal compound.

The card works ok while running windowsXP in 2D. (molex is connected to the card)
Once i fire up 3dmark2003, the airplane battle first test starts shows the battle and after 10seconds goes black screen,...monitor shuts down automatically to standby, i have to reboot.
Tried other different 3dmark2003 test and again, black screen, monitor shuts down. gotta reboot.

Any ideas of whats going on? i think the drivers where nvidia 83.x
System is an Athlon XP 1.5gb of ram, MSI motherboard. windows XP
Capacitors look good, none of them are bulky

i read somewhere that the 7000 series of geforce suffered something similar with power management and needed to use modified drivers. But i have no clue of whats going on with this 6600

Try downclocking and run it on other system.

I must be some kind of standard: the anonymous gangbanger of the 21st century.

6600 doesn't use a lot of power but it could be an old PSU indeed, maybe something from back in the day +5V rails were stronger than +12V.

Nevermind, the Vantec should do the trick anyway. Do have any chance to try the card on a different mainboard?

1) Use latest DirectX (dxwebsetup or full SDK)
2) Try later drivers
3) Plug other Molex into GPU (multi rail PSU, I don't know from where Molex gets that 5V)
4) Did you checked PCI-e to AGP bridge chip (paste/pad, temps) ?

And also - does it only happen under 3dmark or also when gaming?

-fan works ok
-before thermal paste change... 60degrees
-after thermal paste: 45 degrees --temp before running 3dmark.
-i will try with another motherboard, core2duo with agp, asrock
-i did an HDD wipe, will install windows XP with sp3
-will do a ghost image after that just in case drivers mess something.

Old version, preferrably something within 1-3 years from the release of the card.

I had an 8800gt that exhibit the same behavior, stable in XP desktop and black screen soon after demanding power (even w7 aero), it was a burned transistor (I found it after removing the cooler); pretty sure some part of the VRM of your card is toasted.
