So you are back to the original configuration other than the power supply. I think the power supply has a voltage selector switch. If you are in the USA which uses 115VAC and you have the slider switch set for 230VAC the voltages will be too low for the computer to start.

Also re-seat all cards, cables, RAM.

BTW, that power supply is not a very good one. 2 - +12V rails @19A each is not very good. Also only 72% efficient.

One other thought. Do you have the full 24 pin power connector on the motherboard full? Your power supply main connector come as a 20 pin + a 4 pin. You need to use both. They lock together to form a 24 pin main power connector.

You didn't need to upgrade the PSU for that weak video card. The GT 620 has a max power draw of just 30W.

We have no idea if you've connected everything properly but the onboard graphics port generally becomes disabled when a card is installed. The 1st thing you should do is remove the card & connect the monitor cable to the onboard video. Make sure that is working correctly before trying the card again.

Do you get any graphics when first starting the computer?

Does the 620 require an auxiliary power connector?

Try removing the geforce card and connecting to the integrated graphics. This will help determine if the issue is the new graphics card/ drivers or if when you were inside the case you connected something wrong or jarred something loose.

Check that you supplied power to all hardware requiring it. Don't forget the auxiliary CPU power connector.

Couldn't determine the version of the PCIe 16 slot on your motherboard. That could be a compatibility issue with an older version not supporting the new card.

The integrated graphics is AMD and the new card is nvidia. This means drivers will need to be installed.

I upgraded the PSU for more then the graphics card. I pulled the card out and tried the onboard ports and nothing still. The card came with a cd for the drivers and instalation, and no no extra power to the card is required. By aux cpu power cable do u mean the four pin right next to the cpu if so that is hooked up

yes all but power supply is back to stock i have 12G of ram and the only cabeling diffrence is with the old PSU the drives were connected by sata to molex conversions with the new its just sata but i have molex connectors just not attached but the drives still spin up and the whole tower comes on and stays on like their is no problem? idk what it could be unless the ports did get turned off once i put in the new card, but if that is the case shouldnt they turn on when i take it back out?

You do NOT need any drives connected in order to POST. So, the drive controllers are not the reason your not seeing anything.

My guess is that you may have disturbed something. Have you tried to start up while observing inside the case? When doing this is there any indication the computer is attempting to start?

Try clearing the CMOS by using the jumper on the motherboard or by removing the coin battery for 20 seconds. Be sure to unplug the computer or if your power supply has an On/Off switch use it to cut power. Don't forget to restore to the jumper to the run position.

When you restart the computer you must immediately enter the BIOS (setup) screens and reset the date, time, boot order, etc.

When you went back to the integrated graphics did you connect to the same port on the motherboard?

re-seated all ram and card 1 by 1 after a quick wipe on the connectors and works great now thanks to all for the help.
