Hi, so today I tried to swap the gpu and power supply on my PC. The power supply swap was quick and easy but im having trouble installing my new gpu. It's a Gigabyte GTX 660 OC. I uninstalled the driver for my old ATI 6850. I put in the new card but now it won't boot past the blue hp screen that says to "Press esc for Startup Menu". I tried pressing escape to go to the bios but it seems like no keyboard functions are working. The gpu obviously has power because the fans are running and I did plug in the single 6 pin connector. Im stuck and obviously need help!

Hp Pavilion HPE
12gb RAM
i7 2600k 3.4 ghz quad core
ATI 6850 swapping to a Gigiabyte Geforce GTX660 OC
500w CoolerMaster psu
2tb HDD
Thanks

Okay i went to the gigabyte website and am downlaoding the driver now. theyre giving me an option to choose between downlaod types: Driver, BIOS, manual, and utility. do i need to worry about anything but the driver?
 
Do not install the drivers from Gigabyte they are old. Get them from Nvidia http://www.geforce.com/ will get you the latest drivers ver. 320.18. Always get your drivers from Nvidia manufactures websites very rarely have the latest drivers for download.

Tried to downoad the driver from nvidia. it started scanning the computer for hardware then told me it couldn't find any recognizable hardware that matched the 660 gpu. this is obviously correct because the i need to have the old gpu in in order to even do anything on the computer. How am i supposed to download the driver for the new gpu if its telling me i have to have it in? As soon as i put it in the computer doesn't want to boot. Isn't it odd that i can't even access the bios or anything when i put the new gpu in? The computer isn't booting whatsoever. the screen just stays black then eventually shuts off due to "no connection"
