Ok, i tried it in ubuntu, and had the same problem. Now that we have practically worked out that it is not a dodgy card (both have the same problem), im 100% sure it is not overheating and it is not opensuse causing the problems.

Perhaps there is some other hardware conflicting with it?

Weak / dodgy power supply perhaps ?

Yea, it could be a power supply. Or a bad slot on the motherboard.

I have just remembered something i read ages ago. I think it was something to do with conflicting IRQ's and nvidia cards with agp slots on some motherboards. I can't seem to find where i read it though. I'm also not too familiar with this type of subject... and i might be completely wrong

Does anyone know anything about this or if i could find out anything further?

I haven't had to configure IRQs in ages. Most hardware is now plug and play. The best thing to do would be do a google search on that and see.

When we used to have to configure IRQs with jumpers and there was a conflict, it would usually show when the hardware was accessed. Your video problems would show right away, as the hardware got used. So the fact that it works without the nvidia drivers would not indicate an IRQ problem

I was doing some searching and i found something interesting. The nvidia graphics card need their own irq otherwise can lock up while doing intensive operations (3D accel etc)

so i did a "lspci -v" :

From here i can see that other devices are using IRQ 11 as well as the nvidia card. Could this be the cause of the problem? :confused:

How would i rectify it?

How old is your system? Your bus speed is only 66Mhz. Does your BIOS have a setting for non-plug and play OS? If so change it say YES (it may ask "plug and play OS?" then say NO).
see if that helps.

EDIT nevermind about the 66Mhz...it is past my bedtime :p

cybertaz,
I've been fiddling with all the IRQ related settings in the bios and the best i've come up with is managing to change all the IRQ 11 assigned devices to another IRQ together (can't figure out how to change them individually).
So, i was wondering if there is anyway to change the IRQs in linux? (like you could in device manager in windows ...if i remember correctly)

Thanks

I don't know of anything like that. In Suse, I would look in YAST for things like that. Try the hardware section. BE CAREFUL! changing too much in there can get you in trouble.

IRQ problems have almost disappeared since the ISA bus disappeared many years ago. Unless a driver is badly written (not likely), it's very unlikely that the problem is related to IRQ sharing, as this occurs in all other systems around the world without problems. For instance, on my system my ATA controller shares the interrupt with the USB controller, the USB controller with the video card and the two NICs share one interrupt, all without the slightest problem. Have you removed the fan of the cards to check whether dust has accumulated there?

..... advice came a little late...spent the day trying to fix my X server... although i don't quite know what i did, i've managed to get it up again.

Anyway, i have found something interesting (I'm not sure if this is related to IRQs) but when I take out a PCI USB card i have installed, everything works! I have managed for the first time to play games that require 3D support! If need be, i can live with out the USB PCI card but I'd prefer if i could keep it.

Any way around this?

Well, I've managed to get it all working now, i just changed the slot the USB PCI card was in, and it seems to be OK now . I'm guessing it must of been some sort of conflicting hardware problem?
