I have a 2012 M18x R1 that I just got home from having the dual nvidia 560m cards replaced with dual 780m. Here’s where it gets weird. My system sees both cards, but only as standard vga. It does not see my integrated graphics card (not even in bios), but it’s using it to display everything because the new cards aren’t installed. Believe me, I’m ticked at the so called professionals who won’t stand behind their own work. I digress. I pulled the cmos battery in an effort to clear everything, but after I reinstalled it, I got the 5 beep error. No matter what I did to reseat it, I still kept getting the beeps, so I replaced the cmos battery. You guessed it, it’s still beeping. Is there a trick I’m missing? I’ve tried pulling the battery and cmos, pressing fn and power and instead of booting, it just keeps beeping.

help!
