LOTS of problems after installing video card
Well, I just recieved my second 7800gt to go along with my other for SLI and I've had nothing but trouble since putting it in. For one thing, after putting in the card, I couldn't turn on the computer! I didn't mess with anything BUT I do remember accidently taking a cable out when trying to fit the PCI-E 6 pin connector to my video card. It couldn't have been the power supply so I booted up the computer manually with the manual power up button on the mobo.
So I power it up and just a few moments later, I get an error saying "Disk boot failure, insert system disk and press enter". Now when I try to open both my CD drives, neither of them open! The light turns on and it makes this weird "buggy" noise and it just won't open. I have no idea what the problem is and why this is happening. Could it be the graphics card I just added in? I doubt it though as how could it cause so many different problems?
Well I'm real stuck here and could use some help. Thank you all in advance.
