Re: Graphic card not working
Probably obvious, but if it has a power connector have you plugged that in?
Re: Graphic card not working
I don't believe the 5450's are power hungry enough to require a six-pin connector.
Re: Graphic card not working
Make sure you have disabled the onboard VGA if you haven't already. Does the system attempt to boot up, or is there no sign of life?
Re: Graphic card not working
his old ATI card worked so prob not the VGA setting in bios. But checking the power requirements is a good place to start. Can the mobo supply enough power without a separate cable? Can the PSU supply enough current on that output via the MOBO or does it exceed the rail limit? If so you may need a separate cable. One of the reasons I try and go for single rail PSUs where possible.
Re: Graphic card not working
Does windows have the right drivers? The ATI card is a lot older so might have sufficient drivers prepackaged with windows to run it. That said I've never had a new graphics card not do anything at all. Does it display BIOS and the windows start logo on start-up? If so, the likelihood is it's a software/driver problem with windows somewhere.
(I had this with a PCI card once. Windows couldn't handle the fact it didn't need to use onboard gpu anymore and kept wanting to revert back from the discreet card to the onboard gpu. Only solution I found was to wipe it and reinstall windows with the card in place. Et voila, it's worked fine ever since.)
However if it displays nothing at all then there may be something up with the card.
Presume it posts ok with the 5450 installed?

This - try booting the machine with the 5450 in but the monitor attached to the onboard. That'll tell you whether it's a display problem, a set-up problem or an out-and-out card problem. If you can, try the 5450 in another motherboard as well. It doesn't happen often, but sometimes you hit a graphics card and motherboard that just plain won't play nice together (I had it years back with a Radeon 7000 and a SIS-chipset mobo: card worked beatifully in every other motherboard I put it in, but not in that one :rolleyes:).
The only other thing I can think of is to check the 5450 was seating properly in the PCIe slot - again something I've been caught out by before (easily resolved by just pushing a bit harder in my case ;)). It could just be that it needs pushing harder or it could be the heatsink or a component fouling on something...
Re: Graphic card not working
It may be incompatable. I know older nforce chipsets from the 939 days do not support ATI 5 series.
Another guy on OC.AU; he couldn't fix it.
