My guess is the same as yours Paul, and i wonder what error number it comes up with eg (22) or something like that.
On older machines i remember having too specifically to assign IRQ`S for specific device`s and the IRQ`S were listed 0 through to 13, and on these older MOBO`S we assigned the graphics cards between IRQ10 through to IRQ12 because they were genrally unused.
I also suspect the reason this is cropping up is due to the GRAPHICS CARD using the same resources as some other device in his computer, and i hazard a guess its something like a SOUNDCARD/PRINTER/NETWORK CARD or MODEM.
Basically when a computer part wants to get the CPU`S attention, it uses an interrupt, or IRQ. If two devices are assigned the same interrupt,the CPU doesn`t know what device actually needs its attention, so either of two things can happen:
(1)The CPU ignores any message it
gets,and in the case of two
PCI device`s which share the
same interrupt,the CPU will
schedule them for processing
one behind the other.
(2)The CPU processes one device`s
message as though it came from
the other devices.
I would suggest to Paulo to go to the DEVICE MANAGER, double click his DISPLAY ADAPTOR and check his RESOURCES TAB and try to find what it is conflicting with, which genrally shows up as a particular memory range.A lot of times you can get away with this sharing arrangment but if not:
(1)Remove the device it is
conflicting with and replace
in another PCI slot and reboot
to see if it clears the
conflict as it will re assign
the IRQ. Sometimes even
replacing it in the same slot
will assign a different area
of the memory address range.
(2)Try and manually reconfiq the
IRQ and/or memory address range
which is not that simple because
most of the interrupt`s are
already taken by the PC`s other
bits and pieces, which means you
will have to find an unused IRQ.
You need to know what you are doing otherwise you will wind up with more conflicts.
By the way, the 400watt PSU is a bit under powered for the nVidia 9600 and whatever else your system has in it, so i myself definatly would look for something above 550+ watts and dual 12Vlt rails to ease the stress and heat factor as the 400 watt one would be maxed out to breaking point, but i believe it is not causing your mentioned problem. If anything your computer would shut down due to PSU thermal overload because it cant produce the load requirements.
(Sorry for the long winded affair Paul).
