Hi guys,
i have a strange problem with PC. After power loss, PC starts with absolutely no signal on LCD and it won't even beep. Just runs CPU fan, PSU fan, spins HDD, light up LED. But it won't show POST. Only thing which help, is to take off CPU and put it back into socket. But when I shut down PC, press PWR button, it starts again with black LCD and no beeps.
I have reinserted CMOS battery, changed CMOS battery, replugged power cord, changed PSU but nothong worked, only reseating CPU.
It happend me on about 5-6 completly different (new or old) PCs, on different places (if you suspect power plugs in house). It even happened to my friend, and i advised him to reseat CPU and it worked like a charm.
Can somebody please tell me what is going on? Thanx in advance.
P.S. There was one case that PC (with Pentium 4 for socket 775) successfully started after CPU reseating, but then it never worked again (only black screen, fans blowing, no beeps, HDD spining)
