I've just bougt an Asus Ati Radeon 9800xt. It's Smart Doctor utility keeps alerting about voltage. Messages are about "Motherboard cannot supply reliable voltage", "Your voltage is out of safe bıundaries", "VGA ram voltage is not enough" and "Your AGP fan does not work properly". Some times it shows Vcc value as 0.5 V while normal setting is about 3.6. I've replaced the mainboard (MSI 845E series) and also send the graphic card to service. But they could not find any problem. When I repair the Windows, it fixes the problem for a few days (3-4 days actually). I would appreciate any help.
 
Hi;
I doubt that it is motherboard related.
Short of sufficient POWER supplied to the vidcard.
What's your power supply rated at?
That 9800xt requires a lot of amps.

I have a 9800 Pro card that required a separate plug in to the Power supply, not sure if the
XT version has that or it was just my brand (IceQ Excalibur) model? If so, did you find a
spare plug that you could use from the myriad of wires coming from the power supply? It was
a bit tricky to find one.
