I have an Intel MOBO DP55WB. All was fine until I attached my backup drive and clicked restart. The computer would not boot and I hear 2 beeps (a pause) 2 beeps and then nothing blue light remains on but no video. I changed out video card, still no boot
Hello, you may want to remove the power and the CMOS battery for 20 minutes, test the system with the most basic components and try to boot with BIOS configuration jumper in maintenance mode (pins 2-3).
