OK seems like you're having problems with Nvidia brand PCI-E cards and it has to be a problem related to your BIOS because that is what starts the computer up first, Windows and drivers have nothing to do with what is happening at this point.
Ok so from here, we have to come up with the theory of "what could be the error for the card to stop the BIOS's ROM from booting?
Several cards create the same error, so its not the card.
Same PCI-E slot being used each time------POSSIBLE SUSPECT
Used a PCI slot---caused same error----POSSIBLE PCI SLOT OR PCI BUSS ERROR
Lets try this as a possible fix.
Warning: Before proceding with any attempts to repair or modify the inside of any computer, be sure to ground yourself to the computer's case before and at all times while you are performing this task.
The human body is capable of storing lethal amounts of static electricity, which is capable of destroying the sensitive electronic components located inside a computer.
Locate your motherboard's CMOS battery and observe how it is installed, make note of this and remove the battery from the motherboard.
Locate on the motherboard a jumper with the words CLR CMOS. On some computers it is labled CLRTC next to them, there should be 3 pins in a row with a plastic looking jumper on two of them, move this jumper over to the first and second pins opposite of where it was, let stand for 5 minutes.
Return this jumper back to its original pin setting, replace your CMOS battery just as it was before you removed it.
Start the computer and hold down the proper key for entering the BIOS SETUP UTILITY, it is either the F2 or the Delete key.
Your time and date need to be fixed as it was reset and will be wrong.
Hit your F5 key this will load Setup defaults. If there is another option located at the bottom of your BIOS menu called load system defaults choose that option also.
Now hit the F10 key this will pop a box up saying the following SAVE CHANGES TO CMOS AND EXIT? Type Y for yes.
Your computer should now reboot.
