i try reformating my system when it started to keep hanging and there is sound coming from the cpu itself.I didnt try to open up to find out where the sound comes from but couldnt figure out where.After formatting,windows,drivers were all install and everything seems ok but when i try restarting it,there ‘s a error saying “Operating system not found”.i try to reinstall windows again by using both the boot disk and startup disk but cant and was told that there’s no fixed disk found.after trying a few times, there’s nothing appear on the screen anymore.I try restarting,using the boot disk,startup disk,still the monitor doesnt get any signal from the cpu at all.
