I have an msi motherboard (which I think uses AMI BIOS code) and I accidently changed a setting on the BIOS menu and then it restarted and gave me 4 short beeps along with a message that flashed kinda fast saying something along the lines of, "please insert usb flash disk with bios file. "CHECKING FOR USB DEVICE" DEVICE NOT Found." Afterwards I removed anything in the USB slots and tried but still got the same message. I then read that some people solved the issue by removing the power cord and waiting 5 before removing the CMOS . I waited 15 minutes to insure that the extra charge dissipated then removed it. I waiting for about 5 minutes before reinstalling it and now I got 4 short beeps, a pause, and then 2 long beeps. I also have no image on the monitor. I tried looking into the beeps but I couldn't find a description of this code. I could find info for 4 short and info for 2 long but I'm not sure what this means either. I am not over clocking either. It WAS running windows 8.1 Motherboard: 760gm E51- fx GPU: MSI Radeon HD7870 CPU: AMD FX6100 A single 1TB Western Digital black HDD Any help would be much appreciated to solving this.
