Hey, My friend bought this card, after finding out it was on the list of approved cards for the game he runs, (world of warcraft). We installed it, and upon the restart, the computer got to the desktop screen, and rebooted over and over. Then upon total cleaning, rechecking connections, and hooking the monitor to the MB video out port temporarly to get online, we downloaded the latest NVIDIA drivers... reinstalled the card, and PRESTO! it works.... sort of. We can run every application like MS explorer, and word, outlook etc, but when he turns on the game, and it uses the high powered 3D rendering, the card works fine for about 2-5 mins, then the screen hangs up. We can hear from the sound that the game continues to run.
Any suggestions?

Thanks! I believe you are exactly right. first, NO! this card does not have a dedicated fan. It operates with a very large heat sink which is not bolted in or soldered in, but rather uses those crappy spring loaded plastic rivits. And I noticed its loose. Second, the card worked for, like I stated, about 2-5 mins, now it wont work at all. Third, I performed a rude experiment on this situation also.. I took the perfectly functional card out of my computer and installed his..(the one in question). The computer wouldnt even boot. I left the card in, and moved the monitor cable to my MB port temporarly. Still no boot. I left the cable where it now was, and removed the card in question. Computer booted. I loaded the drivers for the card manually, and reinstalled the card, and moved the cable. Nothing. At this point, we're fairly confident the heatsink was not in place well, and has not fried the card.
Thanks for your help!
Always buy a card with a fan on it for todays high powered graphics.
The card works fine whit no driver, but hangs or reboot after a few min. with latest drivers from ATI (maybe they return to theyr habit of making bad drivers :( again). PS: heat problem is out of the question (3 minutes in 12C enviroment temp with open case). DXdiag crashes on Direct3D test. Some game and all aplications works fine for hours, so I don't think is a heat problem

Sounds like an overheating problem. The increased demands on the video card create a lot of heat that is most likely not being dissipated properly. Two suggestions - does the graphics card have a dedicated fan? I am assuming it does, and it likely runs at one speed all of the time. Ensure that the fan is actually spinning when the computer is powered up. Another possibility is to add a whole case fan to push heat out of the computer case (most computers do not come with them but usually have the vent and mounting holes in the back to install one, and a connector on the Motherboard to plug it in - I added one to one of mine that was overheating and it is easy and relatively cheap). Also make sure the computer has free flow of fresh air around it. I have seen many cases where the computer case was put in a computer desk where the case is closed up behind a swinging door with one little vent hole. These do not provide sufficient air flow and computers overheat often. Good computers will shut down before damage, but not all. Good luck!

You know I have to agree Swobovike. A friend of my had that problem and add a fan to blow air over the graphics card and it worked after. He even overclocked and it still worked.

If you can run the v8420 in save mode (f8) then check the voltages. Or check the voltages in the BIOS at POST. If agp voltage is too low, then must get a better power. Some detail power on each rail of 5v 3.3v, and 12v.

Craigbest Did you resolve this problem, as I have the identical problem. I have a heatsink & fan on the card. I also have run my computer with all the covers off to increase air flow, but still the problem persists.
