I have a Palit GTX460 1GB which is out of warranty. it has the latest drivers and bios and what i write below is consistent in three totally different computers .
It has this weird problem :
1. When i install the card as an only card on the system then , when windows try to load the drivers in the "Welcome" splash screen, then the screen gets black even though the windows behind continue to load successfully. When i switch the cable to onboard igpu then i see in the device manager that it returns "Error code 43 , device reported problems and cannot load"
BUT and here is the weird part:
2.When i install it as a second card (the first being a 7600GS or a 7300GS or a GTX 560ti) then the card works perfectly even sending signal to a monitor . I checked it with Msi Kombustor , with phys-x games and with extensive cuda processing.
It seems that only in the first configuration it cannot provide signal for a monitor.
What i can do ???
I mean is there any simple or experimental (i include bios alteration, firmware-driver hacking or anything at all...) way to make it fully usable again ??because there are not any more money ...
