My E-machine T6542 (64 bit AMD processor) is basically dead in the water. Machine is about 2 yrs old. It has never had any problems. Signed up for "auto-update" from microsoft. Installed SP1 & SP2 everything was OK. After downloading and installing SP3 it has been awful. It would disconnect from the internet and basically reboot on its own. Then it would shut off but I could reboot it. Now it simply beeps when I turn it on. Called E-Machines the tech on the other end said I need a new mother board. That sounds drastic. I believe it is a softwear problem. I downloaded a "torrent" and burned it to a CD. Inserted in the machine, nothing. Just beeps. I am not a computer person, I am a computer user and modest trouble shooter. Can fix some things but softwear has me buffaloed. Can you help?
