Its a possibility, but doubt it. If that was the case, you would be prompted to enter the bios every reboot. More than likely, there is either trouble with one of the periphs OR a bad bios setting. Best thing to do is either try booting with bare components (no cdrom drive, floppy drive, basically just the vid card, hdd, memory, processor and kbd (prefer the kbd and mouse to be ps2 type). If it boots add back in one by one, until the problem happens again. This will find the problem hardware. I've seen this happen often with floppy drives and cdrom/dvd. However, DO THIS FIRST. Clear the NVRAM (best to do by jumper) and also disable any sort of bios virus scanning if the mbd supports it. see if this does it. Now this is assuming that it takes forever for the bios beep, and that it doesn't lock up like this AFTER the beep.
