|Sorry will try and explain better.|
My laptop has shut itself down and now freezes on start-up. If I leave it to get very cold gets as far as desktop wallpaper and loads start-up programmes but then freezes. When i try to start again it gets to the Acer screen then freezes, but I am unable to start bios. The next time i try nothing happens but I can hear the fan for a few seconds then it stops but if i wait an hour or longer it may start as far as the windows xp screen but then stops. I have tried changing the memory card with a known working one but it is the same, I have also tried changing cpu but forgot to use thermal paste but it loaded to desktop and froze again. I cant guarantee the cpu as got it off ebay. I tried again using artic silver 5 to connect the cpu to the heatsink but the same thing happens as with the previous cpu. The heatsink does not even feel hot to the touch now, so I am thinking it could be the motherboard or should I try another cpu first..
