I have this boxed, yet dead, MSI NX6800GT graphics card. The box had definitely been opened previously, however the graphics card itself had no dust on it. The fan blade assembly was partially off the stater such that the blade was stuck on the plastic housing (ceased). I pressed the fan back in and tested just the fan with an external power supply. The fan spins fine and isn't noisy at all.
When I put the graphics card into the computer, the screen stays blank at power-up. The fan starts to spin then stops. I tried unplugging the two molex cables from the card and booting, but the card's internal speaker beeps at me, which I suspect is to alert me that the molex isn't plugged in. I tried both DVI ports, still nothing.
Does anyone know common points of failure in these cards, especially ones which don't appear to have seen service? Any idea what I should be troubleshooting? I suspect that the ceased position of the fan may have caused whatever is responsible for the fan controller to fry when the original owner tried to power it up. On the other hand, the ceased fan position may be unrelated. Considering that the fan begins to turn at power-up, perhaps the issue is unrelated to the fan controller?
The card contains a huge solid copper heatsink. Would removing it offer any insight?
I tried the graphics card in 3 different computers.
1) MSI MS-9105, which is a dual Tualatin 1.5 GHz board with 4x AGP.
2) Intel S875WP1-E, which is an entry server desktop board containing a P4 Prescott 3.4 GHz with 8x AGP.
3) Asrock 939Dual-SATA2, which contains an Opteron 185 with 8x AGP.
I don't feel like opening up the cases to check the power supplies, but I recall that they are all at least 400 or 450 W.
All the boards have at least 3 GB of RAM. Could being maxed out on resources cause the MB not to assign resources to the card, causing the issues? Seems unlikely and I've never heard of this happening.
Plan your life wisely, you'll be dead before you know it.
