First Screenshot is of me just scrolling on this site, the second shows the fact that my card isn't rendering ANYTHING in a 3D app.

I haven't been able to check a different vid card yet, hopefully I'll get my hands on a different PCI-E card sometime soon to test if its that or my mobo.

What does this look like to you though? Card temp seems normal if I check it in windows w/ Ntune but it is a bit warm to the touch.

Card is an Nvidia 7900GT, Motherboard is Asus A8NE, 1 gig Ram, I think I have enough fans, and I'm pretty sure that the card fan is spinning, though I don't know how to check what speeds they are going at.

Welcome to tsf. Another possibility is the card is being under powered which also does create artifacting. First make sure you have the latest driver for both the motherboard and the video card. And the latest bios for the motherboard.

If that doesn't do it download speed fan in my sig and post back with the temperatures and voltages it reports. Also post the make , model , and wattage of the psu.

Right I downloaded speedfan, not sure how to give a report but I'll show part of the section of it.


I'll be honest, it boggles my mind that its telling me that only 2 of my fans are spinning, when I open the case they all appear to be working, but I guess most aren't spinning at all....

Anyhow not sure how to get them spinning again, if thats been happening for a while, is the card and/or mobo permanently damaged?

As for the PSU specs, I am not positive where to find them, but I know that its worked for over 2 years without a problem until recently, it does get really loud on startup now if that hints towards anything.

Thank you for the reply as well.

Yeah I built it when the 7900 was brand new. The card is PCI-E

The box of w/e info there goes like this

115/230V~ 10/5A 60/50 HZ
+3.3V +5V + 12V -12V +5V +5VSB
30A 50A 20A 1A .8A 2.5 A

So it two or three years old? Thats psu could be failing. You need a min of 26 amps on the 12 volt rail and there appears to be only 20 , and it very well could be fading.
So I'll probably have to replace the PSU anyway....do you think any damage has been done by it to the card and/or mobo, and if I replace it and still have the issue which is more likely the issue?

It's really hard to say without having a good PSU in there to test it against. Often there's no damage involved by undervolting so let's hope there isn't any.

Right I'll try and get one ASAP.

What was weird to me is that I don't know why the speedfan program shows that only 2 of my fans are actually spinning....

FFVII ftw btw

What he is trying to convey is that not all the fan headers on the motherboard monitor fan RPMs.

There is also the possibility that 3 of the fans not registering don't have an RPM sensor built in.

You could also have those three fans plugged directly into the power supply instead of the motherboard.
