I had the same problem. This solution worked for me.
I removed all my connections(usb,printer, external hdd), removed CMOS battery and pressed the ON button for 30secs. Then put it back and turned it on and then finally I pressed the RESTART button for 5secs.
The motherboard logo with all the boot menu, bios option started popping up.
