What's causing this?

[edtrip]

The stock fans on my Geforce cards, the ones that plug into the card itself, no longer work. If I plug them into a different 3 pin connector they work. I've put in both a gf3 ti200 and an original geforce DDR and the fans don't run if they're plugged into the video card.

Is my motherboard going bad?

It's a Biostar M7vip kt333a chipset. Everything seems fine otherwise.

Thanks

sounds like your card might not be getting enought voltage.... have you tried upping the agp voltage in the bios? it could be your motherboard, but i'd suspect your power supply. What kind of power supply do you have and how old is it?

It's a 300w, probably going on a couple years now, it came with this Inwin mid-tower when I bought it. I think it's a Sparkle.

I'll check the BIOS and see if i can bump the AGP voltage a notch. There's very little in the way of options with this Biostar BIOS.

Thanks

sure, i hope and i can actually be of some help to you. sparkle makes excellent power supplies, although there is always a chance that it could be slowly dieing on you. if your bios has the ability, you might want to check the voltage rails and see if any of the them are drastically off. who knows, it could be that something happened to your agp slot.

Yeah , well i've been into BIOS now, and there's nothing in the way of voltage adjustment, core or AGP - zip. As for the current outputs they are a little on the low side, like 11.76 or so instead of 12, 4.9 something instead of 5, a little off but nothing extreme.

That board shipped with a Warpspeeder overclocking program too, I don't know if it would offer any more voltage options. I never bothered to install it.
