Hello. I have trouble with MB Foxconn 865A01-PE with Pentium IV Prescott CPU. When I press power button, HDD and CPU fan spins up but screen remains blank, there is no beep from MB speaker and LED on MB is blinking. I tried to reseat every component and cable many times, but only way how to get it working is resetting CMOS by jumpers. When I do it, PC boots up normally and works without any problem. But when I shut down that PC, I have to reset CMOS every time when I want to boot. It seemed that the problem is in a battery that keeps BIOS settings alive so I replaced it. When I did it, it seemed that problem is solved and I could boot OS for about three times, but next day the problem returned. This problem has started to appear after I tried to replace that noisy P4 fan but PC didnt start up when I pressed power button so I put stock cooler back. Any suggestions?
