Please Help. No Video

[TheKeVo]

Ok so recently i purchased a new video card, mobo, and processor.
i installed all of them and no video came up on my monitor.
i'm not sure what to do because no one replied when i asked what
i should do, when upgrading all these components, before i shut the
computer down. Should i have unistalled my old video card before
getting ready to install everything. Anything else i should do?

edit: the cpu and mobo is socket 939 (old setup is 754)
the video card is pci express (old one was agp.)
on this new mobo there are no agp slots that the video
card would fit into so i cant put the old one in with the
new one.

the card could be stressing you psu to much on start-up, how big is your psu?

did you by any chance use the same hard drive? you'll either need a reformat, or the motherboard or video card is defective.

my psu: http://www.newegg.com/product/product.asp?item=N82E16817148008

used same hard drive.

would putting all the old parts back together than unistalling the old video card than
putting the new parts back in change the outcome at all?

No, you will need to reformat the pc. There are too many changes done to the setting at the core of the system. If you need to save some files (reformat deletes everything) then put all old junk back together, and save the stuff. OR plug it into another pc as a Slave drive.

Put the RAM into a different slot on the motherborad and try it.

 

[TheKeVo]

both ram sticks into different ones or what
what would that do if i did it

Try them on their own first.
