This is most likely caused by a conflict between your new EVGA card and either your previous card, or your integrated controller. Below are the steps to resolve the issue. Please make sure the card is physically installed in the system and the monitor plugged into the video card itself and not the on board video.
1. If you have an integrated graphics card, please reboot, and at the bottom of the initial screen there will be something stating press Del or F1-F12 to enter either Setup, CMOS or BIOS. Please follow on screen directions to enter BIOS.
2. Once in BIOS you are looking for somehting that says "Onboard or Integrated Video or Display" or somehting like Init/Initialize/Start Display first. If you have the first option, please set it as disabled, if you ahve the second option, et it to the bus type of your card (PCIE(16), PEG, PCI, AGP). If you have any issues locating this, please consult your motherboard manual or the manufacturer directly the the exact labelling and location of these settings, as BIOS is not standardized. From here save and exit.
3. Prior to the Windows loading screen appearing, start pressing F8 repeatidly, this will bring up the Windows boot options. If you get a hardware boot option (CD ROM, Hard Disk etc.) select Hard Disk/Hard Drive and continue pressing F8. Once the windows boot menu appears, please select Safemode with Networking and press enter.
3A. Loading into safemode may take longer than usual, also, you will see ALOT of text and files/paths across the screen, this is all normal.
4. Log in as administrator. Once in, Windows will look blocky and the icons very large, this is also normal. Please procede to your device manager (Right click on (My)Computer and select properties, in Windows 7 it is an option on the left margin, in XP you will need to go to the hardware tab and select Device manager form that window).
5. In Device manager, you are looking for Display adapters. If you find either an older adapter (one you removed) or possibly an Intel graphics, ATI, SYS, something that is not your current card, please right click on it and select disable. It will ask you if you are sure, select YES.
6. Close device manager and go to Add/Remove Programs or Programs and features (XP or Vista/7 respectfully). From there look for anythign that matches the item you just disabled, like Intel extreme graphics adapter, SYS integrated graphics, or anything that says Catalyst (which is ATI). Once it is located, please uninstall it.
7. Reboot back into Safemode with networking, please see Step 3 and 3A.
8. OPTIONAL (steps 8-10) Now we must downlaod the current driver and a driver cleaning utility. I recommend the appropriate drive for your card and operating system found at www.evga.com/support/drivers save the driver where you can find it, do NOT run it from the website. Also download a copy of Display Driver Uninstaller, or DDU for short, (a free utility) from www.guru3d.com/files_details/display_driver_uninstaller_download.html. Click the DOWNLOAD button with a manilla folder icon, this will bring you to download location, select Download America, this brings you to the End User Liscence Agreement, select I Agree and save it someplace you can find it.
9. Install DDU, just let it install with default values. Once into the program, chose your old graphics driver from the drop down menu in the upper left corner, click on the button on the left that says "Uninstall the current adn previous drivers and Shutdown the computer with no rescan" and let it run. Once it cleans out your drivers, your system will shut down.
10. Reboot back into Safemode with networking, please see Step 3 and 3A
11. Please install the drivers from the CD, OR if you have the downloaded drivers from our website, disregard the CD and run the driver EXE. Simply click next on it as it asks and leave all settings as defualt. After it is done you will be prompted to reboot, please do so. Allow it to go into regular mode. Once in you can adjust resolution to preference.
11A. If the issue persists, reboot and follow steps 3-11 including all steps involving driver sweeper.
This should clear the issue. If it does not, the video card may be faulty. The only way to test whether it is the card or not at this point is to try it in another known-working computer and see if the issue persists.
