Computer Won't Start after Installing 5450

[cacacarl]

Hello,

I've installed a ATI 5450 that I got from buying a new computer in an old 2002 Sony Vaio Desktop. Pentium 4 3.20 Ghz, Windows XP. Everytime I put in the 5450 and turn it on the lights would show up but would have no display whatsoever. Please help.

you have plugged your monitor into the gfx card output , right?

You have a PCI-Express slot, right?
Did you disable onboard video in the bios?
Tell us about your power supply.

I changed the PSU to 450 WATT so its definitely not the PSU. I only have the 5450 because it came with a computer I recently bought but changed that computer's card so I wanted to use it to upgrade my old comp. Yeah I have aPCI-Express slot it fits perfectly it won't have any display tho. When I throw in my old card it works.

Bad card and don't get cards that are 2.1 spec for machines that are 1.0 only.

Did you plug the PCI-E card into the PSU?

Most higher end cards require additional power from the PSU, thus new PSUs have at least 1 6 pin PCI-e connector. Some even more, and some even have 8-pin PCI-e connectors, where 2 can be used to moed out of the way.

As your PSU is 400W, it MAY not have a PCI-e connector.

I'm running a 5570 on a coolermaster 350 psu. Make sure you disable the onboard video in the bios and a 5450 does NOT require the pci-e connector. You just might have a bad video card. And with a 450 psu and that rig you can upgrade to a 5670 .

stillerfan15 is right!

Disable onboard video, or switch it to PCI-E, in the BIOS.

Pretty dumb of me but when I try and disable the onboard video in BIOS. Can't find the menu where to disable it .

no, not all motherboards with on board video have the option to disable it. They generally just auto detect that there is another card present and turn onboard off. I have done many upgrades like this recently on intel systems and never had to disable onboard.
