hmm well remove your bat for cmos, power down the socket, directly from the wall, wait up to one hour. Just for trouble shooting sake ,straight this time, to get ride of all possibilities. try it then again. most probably it wont work.
then removing your hardisk...plug into another pc...re-format it again...plug it right back in to your mother pc(might have corrupt segments from a short, which is my guess). Try reinstall again. If same thing happens. See at what stage of the installation. If at the final stage will its detecting your hardware then one of em got hit, if just at the copying stage, then change your hardisk.And try again.....If at the final stage of the installation then iam really sorry man....bad luck....get a breaker socket incase you hit some cables by mistake it wont happen. and check all your wiring for loose end or connections.
o ye and nuke has a point, if it isn’t beeping when you unplug the ram or any other device, that really isn’t a good sign. Your pc got to give you a shout when something isnt right. And if it cant do that then its dead.
So now you will probably have to test every component and see which one is hit. Hopefully only one. And you’ll be up and running fast.
O ye i might be totally wrong and you might have forgot something really stupid like a jumper in the wrong place or forgot the connection to your internal speaker. Or some other dumb thing . That happened to me a few times and by then i was ready to throw it out of the window.
hmmm and from my experience its usually the Graphic that gets it first, followed by the hardisk, then ram. And then what ever comes into your head. i would place my bets on your graphic card . Followed by the ram then the hardisk. And for fu..s sake get a breaker socket if your putting a decent amount of money on a pc.
