I bought a new video card on Black Friday and am having major problems after installing it. I made the mistake of physically swapping it with the old video card without deleting the previous drivers(I know, that was a big mistake now). Now when I turn on the computer it won't boot up. With the new video card installed, it will sometimes boot to BIOS but no further, sometimes it will not even boot to BIOS. I've been reading other posts about similar issues and some said to put the old video card back in and go back in to delete the drivers. I put the old video card back in, but still get the same result. It will either boot to BIOS only or not boot at all. my motherboard is the type with LEDs that will stay lot if it detects an error during POST and sometimes when I try to boot up it will keep the video card LED signaling a video card error, but with no video cards installed it also lights up that LED. I do not have integrated video, so I can't test it without one of the cards installed. I have also flashed the BIOS to the newest version, but it didn't change anything. Please help! I'm worried I have ruined my motherboard..

Asus M5A99X evo mobo
AMD FX-6100 cpu
Sapphire HD6850 (old GPU)
Sapphire R9 280X (new GPU)
OCZ 650w PSU
Windows 7 64bit

What do you mean "the eSATA that the video card was on"? The video card has nothing to do with SATA... or eSATA.

If you had Win originally installed with the SATA mode set to AHCI, it is probably defaulted back to IDE mode now. Enter BIOS and make sure it is set to AHCI if that was how it was when you installed Win. Or visa-versa if you installed Win with the SATA mode set to IDE.

I don't see how you could have ruined your MB simply by changing cards. You may have ruined it if you did the BIOS update wrong, tho. Have you tried resetting the BIOS with the jumper?

How did you update the BIOS if you couldn't get a display?

Whenever you update a BIOS, it usually reverts to default settings. If you had anything changed from default, you will have to change it back. Put your old card back in and (with the PSU off) use the jumper to reset the BIOS to default. You can find the method outlined in your MB manual. See if you can get a display and boot to BIOS.

clutch- Thank you first letting me know that I didn't mess up my motherboard. About every 3rd time I would turn it on, it would boot for enough to get to BIOS. A friend recommended that I disable the eSATA that the video card was on. I did that and now I can boot to BIOS with no problem (the new updated one). I still cannot boot to windows though.

If I try to boot normally from the HDD it brings up a screen that says "windows failed to load because system registry is missing or corrupt". If I boot from the windows disc it gives me an options to run windows repair or boot normally. The repair option does nothing and the normal option brings me to the same failed to load screen as the HDD boot.

the new BIOS version seems to be working fine. It just seems to be an issue with getting windows to load now. Do you think I should still reset BIOS back with the jumper?

Everything in BIOS is set to original defaults but windows still won't load, From the HDDS or the disc. Only exception is that it is on the newest flash version, not the original; I did not do the jumper reset.

Can you boot to Windows Safe Mode (tap F8 at POST)?
Btw, video drivers aren't loaded or needed until you get into the OS (Win). No Windows drivers are required or used before that. The BIOS handles the video basics.

You better work with the old card until you get a working Win system again.
