I have an HP P7-1297c desktop. I've upgraded it, putting in a 450w power supply and a Radeon HD 6670 video card. I have the UEFI shut off in BIOS, and I have Windows 7 64 and Arch Linux installed on the same drive. I boot using GRUB.

Everything has been working fine.


I bought a new video card - an EVGA NVidia GTX 750 ti. I removed the ATI drivers, installed the card, then booted up. When I boot, I get the standard POST screen, but it's frozen - pressing ESC does nothing. After about twenty seconds, there is a short beep, followed by twenty seconds, then a beep, then another twenty seconds, then a third beep. At this third beep, it then goes to my GRUB bootloader, where I can start Windows or Linux. I went into Windows, installed the NVidia drivers, then rebooted. Same thing happened. 

I opened my box back up, reseated the card, and reseated the RAM for good measure.

Same thing.

When in Windows, I can run games just fine. Once I'm in, everything works perfectly - it's just those three beeps, and I can't get into BIOS or get to the boot selection.


I called EVGA, and according to them, it's not a problem with their card. I'm inclined to agree. 

Any idea what is wrong with my poor computer?


Here are my system specs, the power supply replaced with a 450w and with an added EVGA NVidia GTX 750 ti Superclocked:
