Is the bridge properly connected?
Did you enable SLI in the control panel?

+1 for above... and if your psu is old enough, that could be the problem?
you have latest drivers? did your computer detect the second 260?

[shayne]

in anwser to your answers the system does detect the second card for some strange reason
when i put in sli mode it locks the system i will try the bridge connection again to see if any difference thanks for your replys.

Ok things i need to know... PSU info.. Lastest Drivers off nvidia website?

also try each card separatly, there could be something wrong with the second card causing instability.

check drivers. there is a guid around here somewhere on how to remove drivers, but in short, uninstall both cards via device manager, unistall software via programs and features, delete nvidia folder from c:/nvidia. restart windows into safe mode, run driver cleaner, or driver sweeper(i prefer this over the prior). restart install drivers, restart again update directx and enable physx/sli.

if that doesn't work check for a faulty pci express slot, if you're board allows boot with one card in second slot and try a game and check for crashes.

if it's the psu-i would suggest for the gtx260's in sli a 700 watt or higher to be safe. preferably from a respectable brand ocz/bfg/corsair/pcp&c/coolermaster.

if none of this works the last resort i would say is try the cards in another rig, and very last reinstall windows.

some odd issue's that don't fit these descriptions are

heat-check card/cards, chipset/ southbridge(if there is one) and cpu

voltages-if you're oc perhaps the chipset/cpu/ram can't handle the extra card and is crashing

spyware-not sure if this could be an issue or not but it's always good to make sure not errors exist.

i hope i was able to help, keep us posted, i'll keep checking back but i'm at work right now so this is all i can come up with.

^Perfect.. That should either solve your problem or point it out to ya..

Sounds like you dont have enough amps on the 12V or if CPU is overclocked it is taxing the power supply too much.

cheers lads for your replys i will try some of the options you have given me thanks again for the help

[shayne]

ive tried both cards seperatly on there own and both in sli mode even reversed the cards but still getting same results my power pack is a artic 700 psu system seems to run ok until applying sli mode can load up game but when go to play any game it just freezes the system .

[n-ster]

what OS?

[shayne]

vista 64 home premium

[n-ster]

go in add/remove programs, take the drivers out use driver cleaner if you wish then install this

[ntdouglas]

Are you overclocking the cards and/or your system? Go in quick links at the top of this page and enter in your system specs, that way we can better help you.

[n-ster]

yea, always SLI on non-manually oced cards THEN oc them... safer

[shayne]

no i never try overclocking dont really no enough about overclocking also i think it leads to more problems in the end ive posted my system spec if thats any help thanks again

[n-ster]

problem still persists?

[shayne]

yes the problem still persists im just wondering weather to upgrade the psu i dont really know at the moment ive got all drivers for system except the bios but that shouldent effect sli mode thanks again.

maybe your PSU doesn't support SLI?

artic 700 psu

After looking around its OEM is CompuCase/HEC. TBH, not a good OEM at all, I'd look into a brand name, a Corsair 600W would treat you very very well.

Even if it's not the PSU, take this anyways... It simply ROCKS!
