Installed new video card, no signal to monitor, put orignal back now doesnt work

[Brennan]

I ordered a 9400 GT from NCIX to replace my 7900 GTX; I wasn't able to play games because my screen would start showing random textures in the game enviroments and other weird effects before the computer would lock up. I assumed it was the video card because my ram was replaced and still the problems persisted I removed all my nvidia drivers via add/remove programs and shut off the computer unplugged it, took the old card out put the new one in (following the directions from the manual to make sure i dint miss anything) started the system back up (sounded normal new video card fan started running) yet the monitor wasn't getting a signal, i went to shut my computer off by holding the button for 5 or so seconds and it wouldnt shut off, i had to switch the PSU off to shut it down, i put the old card back in and now it doesn't work at all either. Did I cook something? Please helps.

My specs are in my signature, (the ram isnt up to date)

try to use reset the CMOS.... or use the built in video and set the BIOS->initial video to PCIE

Did you check to be sure you plugged in the power cables for the new card?

Post your full specs and explain the issue further so someone can help.
