new video card, no post

Specs: Windows 7
I put another video card in my computer and it will not start the monitor. Now when I put the old one back in, it still will not start the monitor.. No beeps, no post nothing. I reseated the cpu in case i jarred it, I seated the memory again. Any clue?

Is there a graphics card on the motherboard? If there is and the correct drivers weren't installed for the newer card, for outputting visual, the computer will result back to onboard graphics.

"I reseated the cpu in case i jarred it"

You canot "unseat" a CPU, however, you can knock the heatsink loose. If you removed the heatsink to "reseat" it, you destroyed the thermal material. All the old material should have been completely removed & fresh thermal paste applied (& applied correctly) or the system will not boot.

As for the video cards, it would help to know the make/model of both the old & the new. Was anything wrong with the old one or were you just upgrading? Did you check the specs & make sure the power supply was capable of handling the load of the new card? Did you unplug the power cord before messing around inside the case? Did you take anti-static measures?

Do you switch the power on-off switch back to on position at the back of the PSU ?

Did you connect the external power connector to the gfx card if it needs one ( or two ) ?

Before begining to do any work at all on this computer did you:
1) Unplug the PSU
2) Make sure you were carrying no electrostatic charge on your body by grounding yourself to the case?

If not, perhaps you've fried your mobo and that's why you're not getting any beep codes.

If this were me, I'd put the old card back in (assuming it wasn't on the mobo) and I'd see if it boots. If you get absolutely nothing like you are now, it's time to get someone qualified to troubleshoot this for you. If it comes up, then your new video card may be bad. BUT if it is a bad video card, then you should get a BIOS beep code error.

"All the old material should have been completely removed & fresh thermal paste applied (& applied correctly) or the system will not boot."

This is not true. You can boot any system with no heat sink or thermal paste. Once the cpu exceeded its operating temp the system will shut down. But the system would boot until that temp is reached.

Make sure the speaker is connected to the mainboard and both wires going to the speaker are connected to the speaker. No beeps could be a bad speaker.

I was thinking that the video was going out because of the monitor rendomly shutting off. I had a GeForce 9800 in it and was installing a Geforce 460fx. i unplugged the unit first then took out the old card. The new card required a dual power supply so I connected the adapter that was supplied with the card. I did mean the heatsink fan sorry about that. New thermal paste and new clips to the motherboard. All the requirements surpassed before even starting and he power supply is a 750 watt. I took everything apart today and reconnected it all. Even went back to the old card. I turn it on and everything starts up but there is nothing on the monitor, no words, posting, no beeps like normal. As though there is a disconnect between mobo and video cards.

If your power supply does NOT have the correct connectors for the graphics card then it is probably junk. Post the full model of the power supply and the graphics card/s.
