i have a frustrating problem. I ordered the Nvidia Geforce 7900GS AGP 512MB DDR3 from this exact site
after doing some research and checking out more requirements, i discovered that I will also need a new power supply unit considering I have a Dell Dimension 4500 (250W). So I purchased a new psu from dell to ensure it would be compatible with my computer. The exact psu I purchased is below...
as u can see, the psu is 500W and the recommended watts for the video card is 450W. After getting the two in the mail, i started to install them. I installed my new psu first and everything was in place tightly. Then I decided to install my video card. Everything "looked" ok. I booted up my machine and my monitor displayed nothing but my computer was running. I turned off everything and double checked inside my computer. I forgot to plug in the power cord to the psu. I only can plug in two cords. The video card came with 3 cords. One has a set of x1 four bolt pins and x2 four bolt holes. I used x1 four bolt hole to connect in the actual video card thats attached to it. The second cord I used the x1 four bolt pins to connect to a 4 bolt hole from my psu cords. So i have x1 four bolt holes not used. Is that fine? Because my psu cords don't have a x1 4 bolt pin cord with it. After plugging in the power cord, it worked!
Installed the drivers on the CD and then updated the driver from nvidia. After updated, i was prompted to restart my computer. The computer restarted and I shut it down to close my computer case. When I closed everything back up and started it up, i get no display again. I turned off my computer and opened it back up to re-check. Everything was in order and tight. I even took out the video card and re-plugged the power cable and it still was the same problem. I put my old video card back in and it worked liked a charm. Do you think it's because i didn't use both cords from my video card? If yes, do i just purchase a new power cord with x2 bolts pin? System specs below
