I have a manufacturer-built Gateway PC that I've never made any modifications to, but I recently decided to purchase a new graphics card from it. I'm switching from a Radeon 5770 to a GeForce 560 TI. I uninstalled my AMD drivers, rebooted, shutdown, and swapped cards. When I went to boot the PC back up, however, it just made several high pitched beeping sounds. I didn't count how many, I gave it a solid minute and it continued beeping. Any idea what the problem may be?
Note #1: I had the power supply connected using the same cable that was in there for my previous card. One difference I noticed was that my previous card had 1 six-pin connector, while the 560 has 2 six-pin connectors. I didn't try swapping to the other one, as I really didn't want to mess with anything before consulting people who know more than I.
Note #2: With my 5770, I always hear a surge on my initial startup. The fan kicks in high gear for a second or 2 and lets me know everything's on. When I tried to boot with the 560, it was decidedly silent.
My guess and concern is that maybe my power supply isn't giving the card enough juice to boot up? It looks like this is my PS. The card recommends 500 watts, which is this power supply's max, but it also requires a 12 volt current rating of 30A. I have no idea what that part means, and don't see any corresponding numbers on my PS.
Thanks for the help.
