Running Vista. I am attempting to upgrade my power supply (from 250wt to 600wt) cooling fan, add 2 gigs or ram and replace my integrated Intel GMA 950 with a Radeon HD5570. Everything works great except the new graphics card.
I simply plugged the new 5570 into my lone PCI slot and the computer won't boot up. I get power to the PC but it doesn't make any the normal noses (extremely quiet except for fan) and shuts down automatically in 2 minutes or so.
I then switched my graphics settings in BIOS from internal to PCI. I went into Device Manager and couldn't find my integrated Intel GMA 950 but saw a Intel 82945G Express Chipset Family under "Display Adapters"
I disabled it in Device Manager and shut down, popped in the 5570, plugged in my monitor to the cards VGA and tried again.
Same result.
What am I doing wrong?
Thanks!
