I have an acer aspire m3985, and im upgrading from an intergrated Intel Graphics card. I have upgraded the powerpack to 750watt, but when i put the grapics card in and turn my computer on, there is no output, from any slot on either graphics card. What do I do?
Take the graphics card back out.
Turn on the pc and get into bios by pressing the delete button before windows loads. Look for a settimg called 'primary graphics adapter' or similar and set this to 'PCI-E'.
That may solve it.
Doing this tells the motherboard to choose a discrete video card over onboard graphics to boot with.
Hes tried that. unfortunatly there is no option in the bios to turn off the onboard graphics, even updated the bios but still no option. the card works in my computer which is an older acer .... just put in and turn on and away we go. looks like a conflict with the system but just can not find a way around it.
Go to device manager . Find the entries for the display adapter . The intel one . Uninstall it .
When the system prompts for a reboot .. DONT
Instead turn the computer off
Then add the Radeon 6450 , connect to it using either the VGA or DVI connectors
Then reboot . You should get a found new hardware warning if the process is working .
Once you have a desktop then install the AMD drivers
Thanks outlander thought that was a good idea but.... with the same out come im afraid. we tried it firstly uninstall the the display adaptor, then we tried uninstall the adaptor and driver. It would seem like a definite conflict between the the two because when the g/card is put in neither the onboard or the g/card turns the monitor on. we can only get the screen to work with the g/card out.
