Hi, The computer exhibits this behavior on cold boot (computer was off for the night and is powered on): the boot failed, monitor is blank. Sometimes, there is a repetitive long beep. Sometimes, there is no sound, nothing on screen. Even though, hard drive and all fans run OK. I just leave the power on, and push the reset button, and the computer can boot OK. When the computer is running, a warm reboot has no problem. Config: Antec True power 480, probably 4 or 5 years old. CPU is D830, 130 W. 1 hard drive, on board video (S3 Unichrome). Thanks in advance for any advice.
