There is an OLD P3 PC.

When it powered,

01. sometime, it shows the welcome screen of the MB and freez. no beeps.

02. sometime it shows the BIOS loading menu and stuck at "instializing mouse...". no beeps, no answer for keyboard.

03. sometime the monitor just go to sleep mode without showing anything. also it seems the system doesn't boot. fans are working, power led ok, no beeps.

04. but sometime, it boots windows and work without anyproblem.

all those problems were solved after replacing CMOS Battery. but after few days, the problem came again. new cmos battery is still fine. also pc worked without battery before, but not now.

Also I tried removing other attached hardware items one by one. But no luck, there isn't any beeps even only with MB.

I searched on internet, there were lots of topics on the error. but there was no any solution for me.


Please help me.

I think it could be one of RAM, CPU and mobo. I suggest to start with changing the RAM location, clean the motherboard, apply some new thermal grease within CPU and heat-sink.

(Please concentrate on A/Ls. We can sort out all these matters after that. I wish you all the very best!!!!)
