I have problem while starting my PC. After pressing start button, all runs fine, then comes one beep and that's all, no video output, no HDD sound, nothing, only fans are spinning. I've already tried to remove everything that PC doesn't need. Only thing that helps is resetting bios, removing BIOS battery and unplugging energy source, reload default setting for BIOS (i live in year 2001, after start up ). After that PC runs OK for the first time. after reset or shutdown i have to repeat whole action. I thought ROM was not working, but changing motherboard did not help. Please advise.
