Bad radeon hd 6850 or dead mobo?

I just purchased the radeon hd 6850 to replace my geforce 7300 gs. The motherboard is a ASUS M4A79XTD EVO, and the power supply is an Antec Antec EarthWatts EA650 650W.

I put the new card in, and connected it to the power supply with the cable provided with the new card. When i turned on the computer my monitor displayed "no signal input."

I than took the 6850 out and replaced it with the 7300, and the same problem occurred. I than tried to use my geforce 8800 gt which also was working on my computer last week ( I'm using the 7300 gs because the 8800 was crashing me during a game) and once again "no signal input."

Please help!

I cannot get to bios, nothing shows up on the monitor except the message "no signal input," after which the monitor just shows a black screen

No I did not remove the nvidia driver before hand, I have only upgraded nvidia products to nvidia before so i was unaware i needed to do that, im still a novice, but do i need to remove the jumper at the same time the battery is taken out, and I assume i can find the jumper by looking at my mobo manual, but what exactly is the jumper

is removing the jumper done to clear RTC RAM?

i removed the mobo battery for 10 seconds as well as reset the jumper, however the problem is still present "no signal input." i connected my other hdd and its the same thing.

it originally was, but after making it my 2nd hdd i formatted it using windows disk management so it should have been wiped clean.

No there is no display with the 2nd hdd and nvidia card. Do you know what would have caused the mobo to fry, could it be faulty video card wiring or is it just because I did not uninstall nvidia drivers.

I Tested the RAM and still have the problem. If the power supply failed would the fans still spin, the fan on the video card also is spinning.

Problem solved, i redid the steps of resetting the jumper and removing the battery, replaced the ram and checked all connections and I was able to boot using my nvidia geforce 8800 gt. Now I will try removing the drivers and installing hte new card. thank you for your help!
