I recently bought a new HP Pavilion in a box at staples to replace my other aging computer. All was fine and dandy until I realized it only had an integrated video card...
So I opened it up and looked at what available slots it had, and I noticed a two PCI-E x1 and one PCI-E x16. So I went back up to Staples and looked at video cards for the PCI-E x16 slot, and ended up picking up a PNY GeForce 9400 GT 1024MB card. I came home, plugged it in and it didn't work... I did a little troubleshooting and determined my power supply wasn't adequate (I had a 250Watt). No problem, I figured I just needed to upgrade the power supply and I would be good to go. The VC required a minimum 300 watt supply.
I ordered a new supply online and I got it today (400 Watt). I carefully matched the new wires with the old wires to make sure everything matched. I even made sure it turned on before I screwed the PSU into the case. It worked perfectly.
I powered it down happy that it worked, took the old supply out and put the new one in. I powered it up again... it was fine. Then I powered down and unplugged everything to put my video card in. After making sure everything was plugged in nice and tight, I powered it back up with the new video card. It started up but no signal... I realized I forgot to plug the power cord from the VC to the mobo. I plugged it in and the restarted.
I got nothing. The computer turned on, then turned off and kept repeating this until I unplugged it.
So I removed the video card and tried powering up again. Nothing. All it did was start up for a second then switch off... it kept doing this until I unplugged it again.
So then I plugged in my old power supply, and it doesn't work either... it does the same thing.
I know my way around my computer pretty good, but I'm by no means an expert. Does anyone know what the problem may be here?
